Rockford Fosgate Speakers

Would you think it was possible to pack a whole slew of technologies into a pair of car audio speakers? For the fanatics at Rockford Fosgate, that tech translates to more output and better sound in your vehicle. In this product spotlight, we’ll take a deep dive into the Punch Series P1650 6.5-inch and the P1694 6×9-inch sets.

Perhaps the most popular speaker size today is the 6.5-inch coaxial. This size fits into hundreds of models of cars and trucks. The Punch Series P1650 set includes a pair of coaxial speakers that feature mineral-filled, injection-molded polypropylene woofer cones and ¾-inch treated PEI dome tweeters. The addition of minerals like mica helps damp resonances to reduce distortion while improving the thermal stability of the cones.

The cone is attached to the basket with a Santoprene rubber surround that will outlast conventional foam designs. The P1650 drivers use the Vertical Attach Surround Method (VAST) to increase the effective radiating area of the driver for more efficiency and bass output. To ensure smooth frequency response, the P1650 set uses -12 dB/octave crossovers concealed within the basket. Rockford Fosgate calls this its Integrated Concealed Crossover (ICC) design. In addition to being neat and tidy, there are no extra modules (external crossover enclosures) for your installer to deal with, so the installation will be quick and efficient.

Choosing speakers that fit your vehicle is as important as selecting ones that sound great. The P1650 speakers feature the FlexFit2 stamped basket design. This design provides eight mounting holes and eight elongated slots to ensure that the speaker can fit a variety of vehicle OEM mounting points. The mounting depth is specified at 2.24 inches. A set of steel mesh grilles is also included.

Wrapping up the specs on these drivers, we have a continuous power handling rating of 55 watts and a max rating of 110 watts. Their nominal impedance is 4 ohms, and they have a sensitivity rating of 88 dB SPL at 1 watt at 1 meter. Sensitivity at this level typically indicates that the suspension design is optimized for sound quality.

If you have a car or truck with 6×9 speaker locations in the doors or rear parcel shelf and you want to rock out, the four-way P1694 6×9 set is the perfect option. Once again, these speakers include the same mineral-doped polypropylene woofer material as their little brothers and use the VAST surround design for optimized efficiency. These drivers feature a pair of PEI dome tweeters that flank a compact titanium composite cone midrange driver that also includes a rubber surround.

The mounting depth on the P1694 speakers is 3.07 inches, and the drivers include steel mesh grilles and mounting hardware. They can handle 75 watts of power continuously and peaks of 150 watts. Their nominal impedance is 4 ohms, and they have an impressive 91 dB SPL 1W/1M efficiency rating.

It’s worth noting that all of Rockford Fosgate’s speaker and subwoofer specifications fully comply with the CTA-2031 standard for the Testing and Measurement of Mobile Loudspeaker Systems. What does this mean? The dimensions are accurate, and the specifications are entirely believable and uninflated. Not all car audio brands can make this statement.

What You Get When You Spend More Money On Speakers

-

SpeakersAmong the most under-appreciated components in any audio system are the speakers. You could be using the best source unit on the planet, an amazing amplifier, and the most esoteric of interconnects and speaker cables – but if you don’t have great speakers, you still won’t have great sound. Your speakers are the only link between your electronics and your ears, so choosing great speakers is critically important to reproducing great sound. This article discusses what you get when you spend more money on speakers.

More Power Handling

Several factors limit the ability of a speaker to convert an electrical signal into speaker cone motion. One such limit is thermal capacity – just how much heat the voice coil, tinsel leads, former and cone can handle before one of them fails. Heat is the number-one enemy of speakers. Most of the power you send to your speakers is converted to heat rather than to sound – in fact, probably 95% or more is converted to heat.

As the quality of speakers increases, you often encounter a larger voice coil and better cooling technologies. These features, coupled with tighter tolerances around the voice coil, result in a speaker that can absorb more energy without failing.

More Excursion

Speakers
Analysis of the magnetic gap can help engineers increase motor strength.

Often tied directly to how much power a speaker can handle is the distance the speaker cone can move forward or back. This specification is called excursion. For most speakers, the specification for excursion is called Xmax. Xmax is the distance the cone can move in one direction without the voice coil moving out of the magnetic field, and the measurement is typically provided in millimeters.

A second and often equally important specification is Xmech or Xsus. These specifications describe the physical limit of how far the cone can move, based on the design of the suspension (spider and surround). A speaker can be pushed past the Xmax limit, but as this happens, distortion occurs. When a speaker cone reaches its physical excursion limit, distortion will spike even higher. When it comes to speakers, there is no good distortion, so operating them within their physical limits is critical to producing accurate sound.

Why is excursion important? When combined with the ability to handle more power, a “better” speaker will play louder when provided with more power. The same features also help to reduce a phenomenon called power compression. Power compression is a reduction in the efficiency of a speaker as its components heat up. The key drawback to power compression is that when the music gets quieter, you turn the volume up, thereby sending more power to the speaker and accelerating the heating effect. In no time, the speaker will fail.

Excursion Linearity

SpeakersIt’s one thing for a speaker to have good power handling and excursion characteristics. It is equally important that the speaker remains linear throughout its excursion-based operating range. All speakers change in their characteristics as excursion increases – a great speaker minimizes these.

Let’s look at a common problem with “simple speakers.” One of the characteristics that limit the high-frequency response of a woofer or midrange driver is inductance. The voice coil of the speaker has some natural inductance because, well – it is a coil of wire. This inductance is increased when we place the voice coil around the T-yoke of a speaker.

This is where the problem occurs: As the coil moves forward, some of it may leave the T-yoke, which will reduce inductance. As the coil moves rearward, inductance may increase. The result is that the speaker has different frequency responses depending on where it is within its range of excursion. Truly excellent speakers use technologies to minimize these effects. The result are speakers that sound just as good at low to moderate drive levels as they do when being pushed hard.

More Frequency Response

This is a bit harder to describe, because sometimes the improvement from a basic to a mid-priced speaker, or a mid-priced speaker to a high-end one, is extended frequency response. More often, it’s smoother frequency response. Better-quality speakers are, ideally, designed to reduce distortion caused by cone resonances, suspension nonlinearities and magnetic field imbalances. As you spend more on speakers, you will see that peaks in their frequency response, especially in the midbass region, are tamed.

Many great speakers still exhibit some cone resonances at high frequencies. As long as the speaker you are using in the adjacent band will play low enough, those peaks are not critical.

Reduced Distortion

SpeakersWhen a speaker designer combines an appropriately damped and rigid cone with a carefully designed motor and suspension, the result is a speaker that produces less distortion. Some distortions are very subtle, while others are quite pronounced. Speakers exhibit both even- and odd-ordered harmonic distortions, depending on what component or design issue is to blame.

If you have read our article on distortion, then you know that it is the effect of adding content that was not in the original program material. Harmonic distortion results in even or odd multiples of a specific frequency.

When you hear an amazing speaker, the difference between it and an average speaker is clarity. Smooth frequency response and a lack of distortion make each sound the speaker produces more faithful to the recording. Voices will sound more realistic. Instruments will sound more natural. Complex passages will become easier to understand.

It is also critical to point out that distortions cannot be removed from a signal or sound once created. No amount of equalization can extract those harmonics. Yes, you can reduce their level, but you also reduce the level of original signal information at those same frequencies. The only solution is to use a speaker that does not introduce distortion.

The Right Tool for the Job

Speakers
Unless properly installed, midbass speakers in kick panels can have poor response.

Another item that differentiates a good speaker from a great one is its design in terms of application. Let’s use a typical 6.5” midrange/midbass speaker as an example. If the speaker is designed to work in a typical door or rear deck-style installation, the Thiele-Small parameters for that transducer will be optimized for that application. If you attempt to put that speaker into a small kick panel pod that has only 0.1 cubic feet of air space, you will choke it. The low-frequency response will be dramatically reduced; typically, a bump in the midbass region will occur, and it will likely not sound very good. Most 6.5” speakers need an enclosure volume of about 0.6 cubic feet, and some want closer to 1.0 for smooth frequency response.

How do you look for a speaker designed for the right application? That is product knowledge that a properly trained mobile electronics retailer can provide. Do you need a midrange that will work in a small A-pillar pod? Do you need a woofer that will work in an infinite baffle application? Will your midbass driver be used with a subwoofer, or do you need one that will be the sole source of bass in the system? Knowing the intended application for a speaker ensures that the system designer will use it appropriately.

Are More Expensive Speakers Always Better?

Does price always determine performance? In the upper echelon of any audio industry, the rewards for spending exponentially more money diminish. That is to say, the improvement you get from spending $500 on a set of speakers as compared to $200 may not be as dramatic as the difference between $2,500 and $2,200.

Every speaker manufacturer wants you to buy their speakers. They all work hard to come up with great marketing programs to make you want to buy their products. Your goal in choosing an amazing speaker is to ignore the story and listen.

The best way is first to establish a reference. Listen to the best speakers you can find. Don’t worry about the price. You simply want to understand what is available. Then, choose your price point and listen to something in that range. If you can accept the differences, then proceed. If you can’t, re-evaluate your needs or your budget. You can’t get that extra level of clarity, dynamics and detail any other way.

Product Spotlight: Firstech FT-DAS II Security Sensor

-

FT-DAS II Security Sensor

A laptop bag in the back seat, a smartphone in the center console or shopping bags in the rear of an SUV – each is the perfect temptation for a thief. In seconds, items you’ve spent your hard-earned money to acquire are gone forever. Protecting your vehicle with a premium car alarm that includes the Firstech FT-DAS II security sensor is one of the best options for stopping theft, vandalism or damage.

This impressive device includes four security sensors in one compact, reliable package. The FT-DAS II is also a key component in why Compustar or Arctic Start remote car starters are the safest solutions for vehicles with manual transmissions. Let’s take a look at the FT-DAS II in detail.

Firstech FT-DAS II Features

The FT-DAS II uses a high-sensitivity, multi-axis digital motion accelerometer to detect attempts to break into your vehicle or damage from shopping carts or another vehicle. If the device detects a moderate impact, the system chirps the siren a few times to scare off thieves or alert another driver that they may have touched your vehicle. If the impact is significant, the full alarm will sound instantly. The impact sensor is excellent protection against someone using a battery-powered reciprocating saw to try to steal a catalytic converter or using a cordless impact gun to steal your wheels. Your Firstech dealer (Compustar or Arctic Start) can fine-tune the sensitivity of the impact sensor to keep your vehicle safe without having false alarms when it’s windy or noisy.

The FT-DAS II includes programming logic that monitors the accelerometer to detect when the vehicle is being lifted. If someone is trying to steal your wheels or the car is being hoisted onto a flatbed or raised by a tow truck, the tilt-detection feature will trigger the alarm.

The most obvious difference between the original FT-DAS and the FT-DAS II is the inclusion of glass-breakage detection. If a thief uses a hammer or punch to break a window, the microphone will detect the sound of the glass shattering and trigger the alarm.

FT-DAS II Security Sensor
Thieves commonly use automatic center punches to break windows without triggering an impact sensor. The FT-DAS II’s glass-breakage detection will trigger the alarm instantly.

Forward-Motion Detection Delivers Class-Leading Remote Start Safety

The FT-DAS II is required anytime a CM7 or CMX control module is installed as a remote car starter on a vehicle with a manual transmission. The forward motion sensor is active during the remote start process and will shut the engine down immediately if it detects the car or truck moving forward. Even if all the safety systems have been bypassed (which is very difficult to do), you can be confident that your vehicle won’t drive through your garage when you activate the remote starter. No other brand of manual-transmission-compatible remote starter offers this level of safety and security.

Get Security Alerts Remotely

If your remote starter or security system is equipped with a two-way remote like the T13, R5, T12, T11, Q9, 901 or the T9, you’ll get alarm alerts as long as you’re within range of your vehicle. The remote will beep and, depending on the model, tell you which security zone was triggered. The security alerts include warnings for the door, hood and truck triggers and those from the FT-DAS II. For ultimate protection, the DroneMobile telematics system will show alarm alerts as notifications on your smartphone no matter where you are, as long as your phone has access to the internet.

FT-DAS II Security Sensor
If the FT DAS-II triggers your security system, DroneMobile will push an alert to your smartphone almost instantly.

Factory-Installed Security Systems Don’t Offer Damage Protection

You may have been told that your vehicle came from the factory with a security system. In most automobiles, these systems are typically just a transponder key that helps prevent vehicle theft. They do nothing to protect you against smash-and-grab intrusions as they don’t include an impact or shock sensor. A dedicated Compustar or Arctic Start system that includes the FT-DAS II will provide an instant alert if someone is attempting to damage or break into your car, truck or SUV.

Protect Your Vehicle with A Premium Digital Security Sensor

Whether you’re worried about theft, damage in a parking lot or vandalism, a security system or remote car starter that includes the Firstech FT-DAS II is the best protection you can buy. Drop by an authorized Compustar or Arctic Start dealer to ask about a vehicle protection system today. You can learn more about Compustar remote starter and security solutions by visiting their website and following them on Facebook, Instagram and YouTube.

Product Spotlight: Rockford Fosgate Prime R2D2-12 Car Audio Subwoofer

-

Prime Subwoofer

Adding a subwoofer to your car audio system is one of the best ways to improve the way your music sounds. If you are looking for a high-quality subwoofer at an affordable price, the Prime Series R2D2-12 from Rockford Fosgate is an excellent choice. This dual-voice coil 12-inch subwoofer is rated to continuously handle 250 watts of power with peaks at 500 watts. Best of all, you know you’re getting a subwoofer that will sound great and deliver clean, clear bass with minimal distortion.

Physical Features of the Rockford Fosgate R2D2-12

The R2D2-12 is based on Rockford Fosgate’s StampCast four-spoke, stamped-steel basket design. The basket design uses large, rolled edges on the windows to add significant structure and ensure that the motor assembly is secure and solid, giving you the benefits of a cast design without the expense.

The basket also features vents in the base where it’s mounted to the top plate. These vents improve power handling and driver linearity by allowing air under the spider to enter and escape around the voice coil as the cone moves forward and rearward. Features like spider venting are usually reserved for much more expensive drivers. There’s also a sizeable cooling vent in the pole piece to allow airflow from under the dust cap for an extra boost in power handling and performance.

Prime Subwoofer
The embossed and rolled edges of the R2D2-12 frame add significant structural rigidity to the driver.

The voice coil former is made of aluminum to help extract heat from the dual windings, while most woofers at this price point use plastic. The R2D2-12 has a pair of 2-ohm voice coils that can be wired in series or parallel or driven by separate amplifier channels. If you need a pair of 4-ohm coils on your sub, the R2D4-12 is the answer.

Speaker connections are made via a pair of spring-loaded terminals on each side of the motor assembly, with the voice coil’s tinsel leads sewn to the spider to keep them from slapping the cone or spider at high excursion levels. This is another feature that’s typical of much more expensive subwoofers.

Prime Subwoofer
Cooling vents integrated into the bottom of the StampCast chassis enhance power handling and high-excursion linearity.

The cone is constructed from injection-molded polypropylene with mica added for improved rigidity and thermal stability. An inverted dust cap in the center of the cone keeps dust and debris out of the voice coil gap. For compliance, the poly-cotton spider uses a linear design and a half-roll, poly-foam surround treated with a UV inhibitor to ensure longevity and reliability. A semi-rigid, injection-molded trim piece on the mounting flange provides a clean look. The connection between the spider, cone and surround has been reinforced with a multipoint high-temperature, high-strength neck joint bonding technique.

The Prime-Series R2D2-12 from Rockford Fosgate looks great and delivers fantastic sound from even moderately powerful amplifiers.

Prime-Series Subwoofer Applications

When looking at the Thiele/Small parameters, the first thing that stands out is the Xmax spec of 6.4 mm. Unlike most subwoofers that offer an Xmax calculation based on the height of the voice coil and the top plate, Rockford Fosgate’s specification is based on the measured excursion level that produces less than 10% distortion as measured by a laser-based Klippel transducer analysis system. This method considers compliance and motor strength changes for a much more realistic maximum excursion value. Very few companies are this honest and forthcoming with their specifications – quite impressive.

A second important observation is that the driver is impressively efficient. If you have 250 to 300 watts of power, there’s no sense running a giant subwoofer with a heavy voice coil and cone assembly. Rockford Fosgate has optimized this driver to deliver excellent output from minimal power. This is yet another sign that this company knows exactly what it is doing.

In terms of enclosure design, I modeled the suggested 1.02-cubic-foot sealed and 1.79-cubic-foot vented enclosures in BassBox Pro. These enclosures will deliver impressive output from modest power levels, making them perfect for systems with smaller amplifiers or where the electrical system current draw might be a concern in a hybrid or electric vehicle.

Rear Seat Entertainment Systems For Most Needs and Budgets

-

Rear Seat EntertainmentKids and road trips: an amazing combination of excitement, energy and, if the drive is long, boredom. Playing I Spy or 20 Questions, or looking for license plates from all the states and provinces, is fun for a little while, but those classic road games won’t last forever. What if your kids could watch their favorite movies without bothering you? Your local mobile electronics retailer offers many rear seat entertainment options to entertain backseat passengers. This article looks at the most common solutions and how they work.

Overhead Monitors

The overhead monitor is a thin LCD screen that mounts to the ceiling of your car or truck. The screen has a hinge on the top edge so it can be folded up against the roof when not in use. Monitor sizes range from 7 inches up to around 15 inches, with 10-inch models being among the most popular.

Rear Seat EntertainmentMost systems include a built-in DVD player. Watching a movie is as simple as inserting the disc and letting it start. Some systems include USB ports or SD card slots to play MPEG or AVI digital media files. Many units have multiple auxiliary A/V inputs for connections to aftermarket source units or external video sources like a video game system.

Your kids listen to the audio for the movie using a set of wireless headphones. Most of these headphone systems use infrared transmitters, so the kids have to be in the vehicle for them to work; not a problem on the average road trip. Some overhead monitors also include an FM modulator system. An FM modulator will take the audio signal from the movie and broadcast it over an FM radio station frequency. If everyone in the vehicle wants to listen, all you have to do is tune the factory radio to that station.

The installation of an overhead monitor usually requires that your installer cut a hole in the headliner. If you have leased the vehicle, plan on leaving the screen in at the end of the lease. The installer will attach a mounting bracket securely to the roof support structure; then the monitor can be installed. Many overhead monitors include built-in dome lights. The factory dome light location is often a great spot to mount a screen, so integrated lighting replaces the factory unit.

Headrest Monitor Solutions

Rear Seat EntertainmentHeadrest monitor solutions are the same as the screens in an airplane. For the rear-seat passengers, the screens are on the back of the driver and passenger headrests. There are two options for headrest screens: a display installed in most factory headrests, or a replacement headrest unit.

Installing a screen in a factory headrest will require that the upholstery on the rear be cut out to mount the screen. Again, this is a permanent solution. Aftermarket headrest systems vary in quality from manufacturer to manufacturer. Since the headrest is a critical and fundamental component of the safety system of your vehicle, this is not a place to skimp out on quality.

Audio playback typically works the same way as an overhead monitor. One advantage of many headrest systems is the availability of two audio channels. If you have two kids and two completely separate playback solutions, each child can watch a different movie. Headrest systems never block the perspective of the rearview mirror.

Integration with Aftermarket Source Units

Rear Seat EntertainmentIf you have an aftermarket multimedia receiver installed in your dash, then you can probably use that to play movies for rear-seat passengers. Your passengers will still need monitors in the rear, since it’s illegal in most states and provinces to have a video entertainment system playing within view of the driver.

Source units with dual- or two-zone capabilities will typically let you play a DVD and send the audio and video to screens in the rear while the driver and passenger can listen to the radio through the factory speaker system. If this is a feature you want to use, check with your mobile electronics retailer; different brands and models of head units have limitations on what sources can work with what zones.

Alternative Rear Seat Entertainment Options

Rear Seat EntertainmentIf you own an iPad or another tablet, many brackets are available to let you secure those to the headrest mounting posts. Your mobile electronics retailer can install a high-current USB port in the back seat to keep the tablets charged for long trips.

A few companies make monitor systems that attach to the rear of a center console or strap to the seat in front of you. While these solutions don’t integrated with the vehicle as cleanly, they do offer entertainment – and that’s what matters.

If there is no dedicated rear-seat entertainment solution for your vehicle, don’t despair. Many mobile electronics retailers can create something for you from scratch. A custom tablet mount for the seat or center console isn’t a problem for most of them.

If you’re planning a road trip, drop into your local mobile electronics retailer a few weeks before you leave. They can show you the rear-seat entertainment options for your vehicle and book an appointment to have your choice of system installed.
