Product Spotlight: Rockford Fosgate T1650 Euro-Fit Coaxial Speakers

BestCarAudio.com - April 27, 2021

Rockford T1650

If you want a fantastic bang-for-your-buck speaker upgrade for your car or truck, check out the Rockford Fosgate T1650 Euro-Fit speaker set. Using many of the same technologies found in the popular Power Series T1 components, these speakers optimize every dimension to deliver impressive efficiency and great bass output while delivering crystal-clear sound.

What Size Are My 6.5-inch Speakers?

You’d think that cars and trucks that use “6.5-inch” speakers would all be the same, right? The reality is, some OE speakers in this class are closer to 6 inches in diameter, while others are closer to 7. Rockford’s Power Series coaxial speaker offerings include three size solutions to optimize the upgrade in your vehicle. The T16 models are 6-inch speakers and fit in cut-outs with a 5.04-inch diameter. At the other end of the scale are the T1675 speakers, which are a 6.75-inch set and require a 5.68-inch cut-out. In the middle, we have the T1650 speakers that we’ll focus on for this spotlight. These two-way drivers mount in a 5.51-inch cut-out, have an outer diameter of exactly 6.5-inches and require 2.5 inches of mounting depth.

The Euro-Fit T1650 is a true 6.5-inch speaker set with an optimized cone area to deliver excellent efficiency and bass extension when you upgrade your stereo system.

Rockford T1650 Features

The T1650 speakers are based around a custom-tooled, stamp-cast aluminum frame. Rockford Fosgate optimizes the rigidity of the design by including curved elements in both the vertical and lateral axis. Of note, there are four cooling vents near the magnet to let hot air escape from the outside of the voice coil and prevent air from pressurizing under the spider as the cone travels forward and rearward from rest. Also worthy of mentioning is the die-cut foam gasket on the rear of the mounting flange that helps to seal the speakers against the mounting surface. Not many companies include these gaskets, especially at a price point under $150 USD.

The stamp-cast basket features four cooling vents to increase power handling and improve the longevity of the T1650 speakers.

In terms of moving parts, the speakers use a carbon fiber-filled polypropylene woofer cone that’s suspended by a Santoprene rubber surround at the top and a long-lasting poly-cotton spider at the base. Rockford’s Vertical Attach Surround Technique (VAST) optimizes cone area by minimizing the width of the surround. Of course, the design team used its Klippel test equipment during the development process to ensure that these speakers operate linearly to minimize distortion.

At the base of the cone is a 1.1-inch diameter, high-temperature aluminum voice coil former with a winding that presents a 4-ohm load for the amplifier. Spade terminals in 0.25- and 0.205-inch sizes are provided for electrical connections.

One of the features that separate this speaker’s design from most competing products is how the tweeter is mounted. In most 6.5-inch speakers, the tweeter is mounted on a post that extends forward from the T-yoke through the center of the woofer cone. While this works fine, it sacrifices some cone area and reduces the efficiency of the driver. Rockford chose to mount the tweeter on a bridge that extends from the lower edge of the basket. The tweeter is angled upward to allow the installer to optimize the delivery of the highest-frequency information to the listener.

The tweeter itself is a 1-inch aluminum-dome design that has been treated to prevent unwanted diaphragm resonance. Importantly, Rockford Fosgate has integrated a 12 dB/octave tweeter filter network into the speaker to ensure a smooth transition with the woofer.

The bridge-mounted tweeter on the T1650 speakers is angled to help direct the highest of audio frequencies toward the listener.

Going back to the basket design, these speakers feature Rockford’s FlexFit 2 mounting solution. Rather than being riddled with holes, the driver mounting lip includes eight holes and eight slots that make them compatible with a variety of vehicles to save your installer time and hassle. Last and certainly not least, Rockford includes a set of perforated steel mesh grilles with the speakers for custom installations.

Let’s Look at the T1650’s Specifications

While design features are cool, how all those components come together is crucial to recreating your music with accuracy and exuberance. Rockford Fosgate rates the T1650 to handle 75 watts of power continuously and 150 watts maximum. The drivers have a Qts spec of 0.74, indicating that they are designed for installations in an infinite baffle application like the door or rear parcel shelf of a vehicle. This Q factor also indicates that the speakers will reproduce bass without the unwanted distortion that would be found from drivers with Qts values above 0.8. With that said, the compliance (Vas) specification is low enough that an enclosure with an internal volume of 0.5 cubic foot or larger won’t result in unwanted resonance in the midbass region (100-200 Hz).

Finally, the Xmax specification, which describes how far the woofer cone can move forward or rearward from rest, is an impressive 5 mm. This spec is more excursion than on some high-end component woofers in this size range. The transducer design team at Rockford Fosgate knows what they’re doing.

Product Spotlight: Rockford Fosgate Prime Series Subwoofer Enclosures

BestCarAudio.com - April 13, 2021

Product Spotlight: Rockford Fosgate Prime Series Subwoofer Enclosures

Since the ’80s, Rockford Fosgate has had a reputation for delivering big bass for car audio fanatics. Its most recent subwoofer solutions are the Prime Series R2-2X10 and R2-2X12 loaded enclosures. Equipped with a pair of 10- or 12-inch subwoofers, these ready-to-rock subwoofers solutions are a great way to improve the extension and impact of your car stereo system.

Prime Series Subwoofer Enclosures

The R2-2X10 and R2-2X12 are wedge-type enclosures that include two subwoofers in an acoustic suspension (sealed) design. Each enclosure is constructed from 5/8-inch thick MDF to deliver solid bass without adding a huge amount of weight to your vehicle.

The R2-2X10 measures 30.12 inches in width, 12.2 inches in height and is 12.11 inches deep at the bottom. It features a pair of Prime Series R2D2-10 10-inch subwoofers that are wired to produce a 2-ohm load for the amplifier of your choice. The total weight for the R2-2X10 is about 36 pounds. The R2-2X12 is a little larger at 34.06 inches wide, 14.37 inches tall and has a depth of 12.51 inches at the bottom. This enclosure is home to a pair of R2D2-12 subs, which are also wired to a 2-ohm load. The dual-12 enclosure weighs about 43 pounds.

Prime R2 Subwoofers

The R2 Series subwoofers used in the R2-2X10 and R2-2X12 enclosures are based on four-spoke stamped steel frames. The spokes are curved to increase rigidity in what Rockford refers to as its StampCast design. Eight ridges are pressed into the bottom of the stamping to form vents between the motor assembly top plate and the basket. These vents allow hot air to escape from the outside of the black-anodized, 2-inch aluminum voice coil former and eliminate the chance of air under the linear spider from being compressed or rarefied as the cone moves rearward or forward. The extended T-yoke at the bottom of the subwoofer has a large vent to let hot air escape from inside the voice coil and prevent pressure under the inverted polypropylene dust cap. The four 16-AWG tinsel leads of these dual-voice-coil subwoofers are embedded into the spider to eliminate the chance of noise at high excursion levels.

Prime Subwoofer Enclosure
The Prime Series 10- and 12-inch subwoofers feature Rockford’s rigid StampCast basket design that includes cooling vents for the voice coil.

The woofer cones are made from mica-injected polypropylene for an excellent balance of rigidity, damping and thermal stability. An adhesive-bonded foam surround locates the outer edge of the cone in the center of the basket. The basket mounting surface and magnet are adorned with custom-molded PVC trim rings for a clean, classy look.

The Prime R2 subwoofers are rated to handle 250 watts of continuous power with a 500-watt maximum power rating. All models have a specified Xmax of 6.5 mm (0.256 inch) in each direction calculated at the point where the sub reaches 10% total harmonic distortion. All the dimensions and specifications provided by Rockford are compliant with the ANSI/CEA-2031 Mobile Loudspeaker Standard. Likewise, Rockford uses Klippel transducer measurement equipment to optimize its designs for low-distortion, high-output operation.

Prime Subwoofer Enclosure
Large-gauge spring-loaded terminals and tinsel leads integrated into the spider ensure reliable performance.

Amazing Bass Brings Your Music to Life

Based on some quick calculations, the R2-2X10 appears to have a net internal volume of just under 1.7 cubic feet and, as such, delivers an F3 frequency around 58 Hz with a total system Q of 0.68. The larger R2-2X12 has an internal volume of approximately 2.3 cubic feet and an F3 of about 53.5 Hz, and a reasonable system Q of 0.875. As such, when combined with the typical cabin gain found in most vehicles, either of these subwoofer solutions will deliver excellent output well into the infrasonic region while cranking out amazing impact in the upper bass frequencies. The low-Q designs will ensure that your bass is solid and musical without significant resonance and distortion so that every genre of music sounds realistic and enjoyable.

If you’re shopping for an amplifier to work with either of these enclosures, the 500-watt Prime R2-500X1 is the answer. For a little more clarity and definition, the P500X2 from the Punch series is a good option.

Prime Subwoofer Enclosure
The Punch P500X2 or Prime R2-500X1 is a perfect match for either the R2-2X10 or R2-2X12 subwoofer enclosures.

Choosing Speakers For Your Car: Components Or Coaxials?

BestCarAudio.com - April 4, 2021

Choosing SpeakersDeveloping a speaker requires that the designer and engineer balance many different aspects, such as the application, cost and desired performance level of the end product. For the consumer, navigating the thousands of different speaker offerings on the market can be difficult. Two speakers can measure similarly regarding efficiency, power handling and frequency response, but still perform completely differently because of different distortion characteristics. Cone, dust cap and suspension resonance, motor non-linearity, and enclosure/application requirements play a crucial role in determining how the end-product will sound once installed in the listening environment. This article scratches the surface of looking at the benefits and drawbacks of choosing speakers by comparing coaxial and component speaker designs.

When Choosing Speakers, Define the Design

Choosing SpeakersComponent (or separate) speakers are a set of speakers that includes a set of dedicated midrange drivers and dedicated tweeters. Each of those four speakers requires a dedicated mounting location. By contrast, a coaxial speaker features a midrange driver with a tweeter mounted in the center of it. In most cases, the tweeter is on top of an extension post connected to the pole piece. Other coaxial designs use a bridge or mesh grille to suspend the tweeter over the midrange. These are sometimes called coaxially mounted components by marketing departments.

Benefits of Coaxial Speakers

In most cases, coaxial speakers are the less-expensive options in a product lineup. This pricing is due to the chosen target customer and not because you can’t make a high-quality coaxial speaker. Less-expensive magnets, baskets, cone materials and suspension components, and wider tolerances that allow for faster production with fewer rejected assemblies, all help reduce cost. The benefit is, if you need an inexpensive speaker, coaxials are a good solution.

Coaxial speakers can be installed faster, so they are less expensive to install. The integrated tweeter saves a lot of time during the installation process. Most coaxial speakers have integrated crossovers of some sort that don’t require special wiring or mounting. The net result is that your installer can get them up and running in your vehicle in about half the time it takes to install a component set, which means your labor charges will be reduced.

Benefits of Component Speakers

Most component speakers are made from better materials and have higher performance goals. High-end components can cost more than $5,000 for a set and often include premium passive crossover networks, elaborate installation accessories and – of course – amazing speakers. The sound that component speakers produce, when installed and tuned properly, can be amazing!

When a good set of components is tuned properly, most of the sound can appear to come from the tweeters. Having a separate tweeter allows your installer to mount it high in the vehicle – at the top of the door, on the dash or in the A-pillar. The combination of proper tuning and placement puts the music out in front of you, essentially at eye level. This higher soundstage is similar to what you would experience at a concert, listening to the band performing in front of you.

Choosing SpeakersMany factors contribute to where and how your installer mounts the tweeters – your budget, your performance goals, and how much modification you want or will allow to your vehicle. All locations have their benefits and drawbacks. For example, a tweeter mounted on the dash or A-pillar is very near the windshield. The hard surface of the windshield can cause significant reflections. Alternatively, a mounting location in the upper section of the door may reduce these reflections, but may not raise the soundstage as high, or could make it appear to come from somewhere closer to you than the dash or pillar location.

A component speaker doesn’t have any of its output blocked by the tweeter, which eliminates some minor reflections . Likewise, with a coaxial speaker that uses a tweeter post, a component speaker can have a full dust cap. The dust cap moves with the cone and increases the driver cone area. Additional cone area increases the driver’s efficiency.

The Huge Role of Crossovers

Choosing SpeakersWhether you choose a coaxial or component speaker set, you are going to need a crossover to handle splitting up the frequencies. In the most basic of speakers, a capacitor is used on the wire going to the tweeter to block low and midrange information. The midrange driver is allowed to roll off naturally – ideally, there are no significant high frequencies resonances that will affect the sound.

As you progress up through the quality of a speaker set, you will see steeper filter networks on tweeters. These steeper networks allow the tweeter to play to a lower frequency and then be stopped to protect it from excursion damage. At the same time, filtering the high-frequency output of the midrange is common in mid- to high-end crossover networks. Speaker manufacturers construct the most elaborate of crossover networks with premium components for both the high- and low-pass portions of the network. Adjustability is often built into the crossover for tweeter level. Small components can be overdriven and saturated, reducing their effectiveness. Large amounts of distortion can cause the tweeter cap to overload and explode.

The Option of Coincident-mounted Coaxial Speakers

Choosing SpeakersThe radiation pattern of a speaker is a sphere in its standard operating range. As frequency increases, this output pattern becomes more directional. When a tweeter is mounted at the base of a midrange, a phenomenon occurs called Intermodulation Distortion. As the cone of the midrange moves up and down to reproduce music, this moving surface modulates the reflections of the tweeter.

It is worth noting that the same thing happens when a single speaker cone is asked to reproduce high frequencies: The source of the high-frequency sounds moves forward and rearward as the speaker cone attempts to reproduce lower frequencies. This modulating effect is known as Doppler Distortion. These distortions, combined with the narrowing of the radiation pattern as frequency increases, are some of the many reasons why we have to use different-sized speakers to reproduce music accurately.

When shopping for a coaxial speaker, you will want to choose one that has the tweeter mounted low enough not to interfere with the installation of a grille or trim panel over top of the speaker. You should also look for a tweeter that has a small waveguide that prevents the output from bouncing off the midrange cone.

Shopping for Speakers

We could spend years discussing the different aspects of speaker design and performance. Suffice it to say that you should seek out the assistance of a seasoned and reputable professional for purchase and installation. Be sure to quantify as much of the purchase process as possible – your financial limits, cosmetic preferences regarding installation and performance goals for the system. You will want to use music you have listened to many times when auditioning speakers.

You may want to listen to both a set of more- and less-expensive speakers to help quantify the price point you have chosen. Finally, talk with the salesperson and, if possible, the installer about how and where the speakers will be installed. Be sure to ask about sound deadening, spacers, wiring and anything else that can affect the performance of the installed speaker.

Speaker shopping is a lot of fun, and getting new speakers for your car, truck, boat or motorcycle can be very exciting. Be patient – take your time and be thorough. You will enjoy your new purchase all that much more when you choose a great-sounding speaker and a skilled installer.

The Importance Of Proper Car Audio Speaker Installation

BestCarAudio.com - March 7, 2021

Speaker InstallationThe speakers in your mobile entertainment system are one of the most critical components in determining how your system sounds. If you choose poorly designed speakers that have distortion issues from poor cone, suspension or motor design, no amount of signal processing can make your system sound great. The methods used to install your speakers are as important as the design of the speakers themselves. In this article, we are going to look into some of the common mistakes that occur during speaker installation and how to maximize the performance of your speakers.

Speakers Need A Stable Foundation

Speaker InstallationIf you want to listen to a record player, you want the unit to be on a solid table or stand. You’d never try to hold the turntable on your lap – the needle would jump and bound all over the place. When it comes to speakers, you want all the energy from the motor to move the speaker cone and not the basket. Why would the basket move? Newton’s Third Law of Motion states: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.

When the voice coil pushes the speaker cone out, the inertia of the cone is also pushing back on the fixed magnet. If the speaker isn’t mounted securely, it will buzz, vibrate and otherwise move around. These vibrations cause all manner of distortion.

Look at a set of high-end home audio speakers. Years ago, Linn had a set of narrow floor-standing speakers that used a pair of small midrange drivers, roughly 4.5 inches in diameter. The front baffle of the speaker enclosure was 1.5-inch thick MDF. If you knocked on it with your knuckles, it sounded like concrete. And yes, those speakers sounded excellent!

Speaker Installation – Consider Mass

To combat the forces generated by the moving speaker cone, you will want to consider beefing up the mounting surface. In the case of a subwoofer enclosure, an extra-thick front panel can help. Vertical braces on either side of the speaker mounting surface help even more. The best solution is to run full-size braces from the front of the enclosure to the rear. Full depth braces lock the front and rear panels together and add dramatic strength to the speaker mounting surface. These braces also control vibrations in the rear panel to improve performance further.

For a smaller speaker such as midrange or midbass driver in a door, adding strength is a little more difficult. The most common practice is to add a layer or two of butyl damping material (sound deadening) to the metal around the speaker. You can even add a layer or two on the inside of the door skin if you are concerned about thickness. Damping materials with an aluminum layer add a little extra mass.

Speaker Installation
These plastic speaker adapters by the crew at Mobile Edge will last the life of the vehicle.

If your installer is constructing a set of speaker mounting adapters, then ask if they are using a material that has some mass to it. HDPE and ABS are good; acrylic is even better. A material like Corian – the DuPont countertop material – is fantastic. You can easily cut and shape Corian and glue parts together with Cyanoacrylate (Crazy Glue). You may want to use thread inserts or t-nuts with all of these materials. While it is readily available and easy to work with, don’t use wood for speaker adapters inside doors – it will get wet, swell up and deform. It can also hold water and get moldy.

Speaker Installation – Location Matters

Speaker Installation
This enclosure, by Handcrafted Car Audio is perfect for maximizing the bass output without taking up any usable hatch space.

If your audio system is going to use factory speaker locations, most of the time these are acceptable to provide an unobstructed output path to the listening area. The last thing you want to do is block the output of the speaker by putting something in front of it. Keep magazines, books, paper and other objects from piling up in front of, or on top of, your speakers.

For subwoofers, the location of the sub has a dramatic effect on how it sounds. You want the energy from the subwoofer to be able to mix with the sound from your midbass speakers as easily as possible. For this reason, hatchbacks and SUVs are great for bass. If you have a sedan, then firing the output of your subwoofer through a ski pass-through works well. You can get away with firing subs into the trunk of a sedan, but you will want to ensure that your midbass drivers can play fairly low – say 75 Hertz or so – to ensure that you don’t lose impact and dynamics.

Back-Wave Cancellation Problems

We use speaker enclosures for two primary reasons – to limit the movement of the speaker cone and to prevent the sound coming from the rear of the speaker cone from canceling out the sound coming from the front. You need to prevent the rearward sound from mixing with the front. For midrange speakers, this means building good quality mounting adapters. Your installer can also use sound-deadening materials to seal up openings in the interior skin of your door panels. You will get better speaker performance with proper back-wave management than you will just buying better speakers.

Weather Protection Ensures Longevity

Speaker Installation
In another Handcrafted Car Audio installation, they were fortunate enough to have room to build a sealed enclosure for these midrange speakers.

When mounting speakers in a door panel, it is inevitable that the back of the speaker will get wet. The interior of doors are not completely watertight, and this poses a challenge for installers. Creating an enclosure out of a water-resistant material would be the perfect option, but there is rarely enough mounting depth and it is difficult to create an enclosure that is large enough not to affect the performance of the speaker. For many years, installers have used foam ‘hats,’ cut in half to protect the top of the speaker from direct exposure to drops from the window seal. These are a good option. A thick foam gasket mounted behind the speaker mounting surface can also help. Companies like SoundSkins and F.A.S.T. Rings have ready to apply pre-cut solutions.

There are dozens of other considerations when it comes to having your speakers installed. The most important task for you is to partner with a retailer that does high-quality work and has an excellent reputation. Choosing great speakers for your car audio system is a lot of fun. Hearing them perform up to their potential is even better.

Product Spotlight: Rockford Fosgate R2-750X5

BestCarAudio.com - March 4, 2021

Rockford R2-750X5

In the spring of 2020, Rockford Fosgate launched the latest generation of its Prime Series amplifiers. While the focus of this spotlight is on the full-range Class-D five-channel R2-750X5, it’s worth noting the R2 series also includes a two-channel, two four-channel and four monoblock models. Equipped with features and technologies that have trickled down from the Punch and Power series, these compact yet powerful amplifiers are ready to bring your music to life.

The Basics – Features and Ratings

Rockford leads the car audio industry with power specifications you can trust. The four main channels are rated to produce 50 watts of power into 4-ohm loads and 100 watts into 2 ohms. The front channels can be bridged to provide 200 watts into a pair of 4-ohm speakers. The subwoofer channel is rated for 200 watts at 4 ohms and 350 watts at 2 ohms. In total, that’s 750 watts – just like it says in the model number. Signal-to-noise specifications are -80 dB for the main channels and -75 dB for rear, and just like the power ratings, these numbers are fully compliant with the CTA-2006 testing standard.

If you look at Rockford’s website, you’ll see another set of power ratings. Tested using their internal RATS (Rockford Automated Testing System) and verified by the Audio Graph PowerCube, these elevated numbers represent the real-world power production capabilities of the amp when playing music that’s dynamic instead of single-frequency test tones. The Dynamic Power numbers are 70 watts by four and 241 watts for the subwoofer at 4 ohms, and 114 watts by four and 426 watts by one at 2 ohms.

Rockford R2-750X5
The Rockford Automated Testing System (RATS) is used to verify the continuous and dynamic power capabilities of amplifiers like the R2-750X5.

Rockford R2-750X5All of the electrical and signal connections are found on the front edge of the amp. Angled terminal blocks for four-AWG power and ground cables are next to the five eight-AWG speaker output connection blocks. The amp includes six RCA input jacks that will accept up to 4 volts of signal. Beside them are three jacks for the included speaker-level input pigtails. All of the inputs use balanced differential circuitry to help prevent noise from getting into the audio system. The high-level inputs will accept up to 12 volts, and an accompanying switch labeled Auto Remote Turn On will bring the amp to life when it detects that your factory radio has powered on. A three-position input selection switch allows the amp to feed all five channels from four or just two of the inputs to eliminate the need for Y-cables.

Rockford R2-750X5The controls have been placed along the top to make it easy for your installation technician to configure the amplifier. The front and rear channel pairs have dedicated sensitivity adjustments and crossover function and frequency controls. The filtering can be set to high- or low-pass modes, or bypassed. The crossovers are adjustable from 50 to 250 Hz and have a -12 dB/octave Butterworth response curve. The subwoofer channel shares the same low-pass filter frequency adjustment range as the main channels and adds an infrasonic filter that’s adjustable from 15 to 40 Hz. The last control is the Punch EQ adjustment that your installer can use to add up to 18 dB of boost at 45 Hz to the subwoofer channel. Rockford includes a remote level control so that you can adjust the subwoofer level from the front seat.

Rockford Technology Improves Performance

Rockford R2-750X5If you’ve been a fan of Rockford products for a while, then acronyms like MEHSA, P.O.W.E.R., C.L.E.A.N. and NOMAD should be nothing new to you. What is new is finding all of these features on a Prime Series amp.

The amp is based on a 1.9- by 6.8- by 11.2-inch cast aluminum heatsink that wicks heat away from the switching devices quickly and efficiently. Rockford calls this design MEHSA 4, which stands for Maximum Efficiency Heat Sink Application version 4. What this means to users is that the amp will keep making its rated power hour after hour, even with the volume cranked. Sure, the heatsink will get hot – but that’s its job. MOSFETS don’t like being hot. In fact, their maximum current capacity drops quickly as they heat up. A thermal design like MEHSA 4 extracts heat from the output devices to reduce distortion, improve efficiency and extend the life of the amplifier.

Rockford R2-750X5The R2-750X5 includes a power supply design called P.O.W.E.R. This lightly regulated configuration increases maximum power output capability as the charging system supply voltage increases. Speaking of which, this amp is designed to work with supply voltages from 9 to 16 volts.

In terms of protection, Rockford’s NOMAD (NOn-Multiplying Advanced Decision) circuitry monitors the amp and will mute the outputs if it detects a short circuit on a speaker connection or an over-temperature condition on the chassis.

Perhaps the coolest technical feature in the R2-750X5 is the C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) circuit. C.L.E.A.N. monitors the input and output connections for distortion. On the input side, the circuit monitors the signal from your radio for distortion so your installer can identify the maximum usable volume setting. On the output side, the monitoring LEDs turn red when the amp starts to clip the output signal.

Upgrade Your Car Audio System with Rockford Fosgate

If you are shopping for a high-performance multichannel amplifier to upgrade your car audio system, visit your local authorized Rockford Fosgate dealer and ask about the Prime Series R2-750X5. You can find a shop near you using the Dealer Locator on the Rockford website.
