W3v3 H.O. Wedge

The benefits of JL Audio’s patented, chamber-coupled port design are now available in five outstanding W3v3-based high-output ported systems. These potent systems deliver outstanding impact and sound quality in medium power applications.

The JL Audio HO112RG-W3v3 is an insanely powerful H.O. (High Output) system that delivers a very high SPL while retaining excellent sound quality. It uses a patented, chamber-coupled port design to minimize turbulence and maintain excellent sound quality at all listening levels. The system also includes solid aluminum bar grilles for woofer protection. JL Audio's H.O. systems are designed specifically to provide excellent sound quality and amazing output. You will not be disappointed with a JL H.O. subwoofer system.

Loaded with what is easily the best selling subwoofer driver, next to the W6v3, the JL Audio W3v3 provides phenomenal performance at moderate power levels with superb sound quality. The W3 series is in its 3rd iteration, embodying the series' pursuit for providing outstanding output and world-class sound quality. This is accomplished by utilizing a whole suite of advanced technologies originally developed for JL Audio's flagship W7. An Elevated Frame Cooling design helps in delivering enhanced power handling and sound quality. The DMA-optimized, long linear excursion capability minimizes distortion and increases output, while multiple patented technologies enhance performance and reliability. Such advances make the v3's the best sounding, most reliable W3's yet.

Although the W3v3 Subwoofer can be driven with as little as 150 Watts, for best audio performance it is recommended to run an amplifier capable of between 300 - 500 Watts of continuous power per driver, like the JL Audio XD600/1v2.

JL Audio Patented Cooling Technology

JL Audio's patented Elevated Frame Cooling design delivers cool air into the heart of the subwoofer in ways no other manufacture's driver can. Purpose-engineered slots located directly above the top-plate stream air to the voice coil. In addition, the upper surface of the top-plate is directly exposed to this airflow, whereas on a conventional design it is isolated from this flow by the lower flange of the frame. This technology not only increases thermal power handling but also sound quality by minimizing dynamic parameter shifts and power compression. In plain English, this driver keeps itself cool so you can play your system longer, safer, and without having to worry about frying the motor.

Tight, Clean, Articulate Bass

DMA is JL Audio's proprietary Dynamic Motor Analysis system and is aimed at improving dynamic motor behavior. As a result of DMA optimization, W3v3 motors remain linear in motor force over an extreme range of excursion and also maintain a highly stable fixed magnetic field in the gap over a wide power range. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. Its main catalyst is the driver's Ultra-long Voice Coil, which allows extreme linear excursion, phenomenal power handling, and control, control, control.

Awesome product

Got 1 of these in the back of my aura xr and it sounds awesome! Got it hooked up to a jx500/1d and I'm very happy with my system. The box is perfectly tuned, looks great and doesn't take up much space at all in my trunk.

Clean sound, sleek design

Big improvement over my Kicker L5, which took up my entire trunk. Now, I get cleaner sound in a more low profile enclosure which pretty much disappears in my trunk.

Needed something that wouldn't kill the trunk space in my daily driver accord, due to having kids and this fit perfect. The output is amazing and more than I was expecting. Running 500w RMS thru a jx500/1 and still have plenty of room for family trips.
