One crucial factor when purchasing speakers for your car or truck is choosing a model that fits the available space. While it’s most evident that the diameter or outside dimensions need to suit the available space, the speaker depth is also crucial to creating the installation. When the available mounting depth makes it seem like a high-end upgrade is impossible, Morel has an answer – the Virtus Nano Carbon Integra 62. Let’s check them out!
Morel Virtus Nano Carbon Integra 62 Features
The key feature of these speakers is their diminutive mounting depth. Before we look at that, let’s explain what you get. The Virtus Nano Carbon Integra 62 is a set of 6.5-inch Integra 6 coaxial speakers that includes high-quality grilles and MXR 200.3 premium passive crossovers.
The key element is the woofer cone, with its unique woven carbon sandwich construction. Morel has implemented what it calls Grand Dome Geometry. The convex shape is a crucial part of the design, balancing impressive performance with a remarkably shallow mounting depth. The solution balances rigidity, mass, and damping to deliver exceptional performance.
Specifications and Application Information
Morel rates the speakers as being able to handle 100 watts of power continuously, with peak power handling at 300 watts. The speakers have an efficiency rating of 87 dB SPL when measured with 2.83 volts at a distance of 1 meter from the microphone. Frequency response is specified at 50 Hz to 25 kHz.
With respect to electromechanical requirements, the Integra 62 woofer has an Fs of 73 Hertz, a Qts of 0.73 and a VAS value of 0.26 cubic feet. The effective cone area of the woofer is 17.98 square inches, and the maximum linear excursion is 0.12 (3 mm) inches in each direction. They are designed to work in infinite baffle applications like a car door, kick panel or rear parcel shelf. Should your application call for an enclosure, you’ll want about 0.6 cubic feet to keep the total system Q under 0.8. An ideal enclosure would be about 1.0 cubic foot per driver, resulting in an F3 frequency of 77.3 hertz and a Qtc of 0.765.
Shallow Mounting Requirements
As you can see from the photos, the mounting requirements of the Integra 6 woofer are incredibly small. From the mounting surface, the woofer needs only 0.7 inches or 17 millimeters of depth. That’s right, the cone, voice coil, basket and motor will all fit within the confines of a piece of 3/4-inch thick MDF. Now, they do need airspace behind them to function correctly, but from a physical requirement, they are about as thin as a high-quality speaker can get.
What’s really cool is that Morel has patented the geometry of the speaker with respect to using a single neodymium magnet to power the woofer and the tweeter. The result is the thinnest car audio speaker on the market, and one that happens to sound excellent.
The Integra Tweeter Design
You’ve likely noticed the integrated tweeter design that Morel calls Integra. In essence, this is a point source tweeter implementation that helps provide a smooth and predictable output both directly in front of the speaker, as well as off to the side.
The tweeter diaphragm itself is made from silk and features an Accuflex coating to help prevent resonances at extremely high frequencies. The tweeter has a relatively massive 1.125-inch (28 mm) voice coil and a resonant frequency of 1,000 Hz. This allows the system to be filtered at an impressively low 2.2 kHz with second-order slopes. Why is this impressive? Most 6.5-inch midrange speakers become quite directional above 2.5 kHz. So, when combined with the Integra tweeter design, these speakers will sound amazing from almost any listening position. When you have a speaker mounted low in the driver door or kick panel, these design criteria make a considerable difference in performance compared to most offerings on the market.
Premium Performance
The Integra 62 speakers aren’t just shallow; they are a high-end speaker in their own right. Morel uses a 2.16-inch aluminum voice coil former on the woofer with their Hexatech aluminum winding. The compact winding results in a nice low inductance value of 0.17 millihenries. This low inductance helps improve midrange performance. You can see the smooth output to 2.5 kHz in the frequency response graph above. The nominal impedance of the woofer is three ohms, so it will work with the amplifier built into a radio, while also maximizing the performance of external amplifiers.
Premium Passive Crossover
As mentioned, the Virtus Nano Carbon Integra 62 set includes premium passive crossover networks. The MXR 200.3 networks feature high-quality components like polyester capacitors and air-wound inductors. The tweeter output level can be adjusted in two steps from +2dB, 0dB or -2dB to compensate for personal listening preferences.
An Upgrade That Fits Almost Anywhere
If you’re looking for high-end car audio speakers that fit almost anywhere, consider visiting an authorized Morel retailer in your area to audition the Virtus Nano Carbon Integra 62 set. Morel also offers a two-way component set with a similar woofer design and a three-way set with an equally shallow 2-inch midrange driver.
You can find an authorized Morel retailer near you using the Locator on their website. Be sure to check out Morel on Facebook, Instagram and YouTube to stay up to date with their impressive offerings.
