Clean and Efficient W3v3 Series JL Audio Woofers

The JL Audio 12W3v3-4 is rated at 500W RMS and features a single 4 ohm voice coil. This woofer will perform like a well oiled machine. It will provide unbelievable sound reproduction with deep, rich and responsive bass. This woofer sets the standard for what a 12" woofer should look like and more importantly what high-end should sound like. Most other subwoofers will offer power but lack performance or offer performance and lack power. The 12W3v3-4 will not only give you power and unmatched performance but it will also offer many more things which other woofers just can't compete with.

JL Audio is all about performance and quality. They manufacture products to meet extremely high standards and anything less than those standards is not good enough to carry the JL Audio name. The W3v3 subwoofer is one of the cleanest, most efficient, and best sounding subwoofers in its class. This series is available in a 6.5”, 8”, 10”, 12”, and 13.5” size woofer that can pretty much fit any vehicle size. The W3v3 features a DM Optimized Motor System that provides constant and strong linear excursion that result in reduced distortion and higher bass reproduction. These woofers also feature Elevated Frame Cooling technology that delivers cool air directly to the voice coil of the woofer. This increases power handling and sound quality. The W3v3 series subwoofers offer many more patented technologies that truly make this series stand out above the rest. If you are struggling on a decision, the decision if simple JL Audio, it will never disappoint.

Okay I've had numerous subs in the past few years from SPL to now SQ now to give this sub an amazing review I have to compare it to subs in its class . I bought a Type R three years ago from Sonic and I absolutely loved that sub but the problem I came into contact with was there was not a very good low bass note. I tune all my subs to specs of the manufacturer. The type are is awesome loud and can handle great power but I recently bought a w3 from a car audio shop in the area as im trying to with a sq setup to be honest I love this sub more than my Type R I have it tuned where JL says and have the perfect JL amp on it. To be honest this sub has hooked me into JL for life. My brother now has the Type r and it is still pumping which is impressive considering I had the subs on 800 rms on a cea certified amp. Yeah the sub is expensive for the watts but the sound that comes out of this sub is amazing it can play country rap rock and rock and will even hit the low notes from slowed down music ....if you want the best of both world sound quality and a sub that will punch you in the stomach get this sub I cant write enough about it !!!!!! JL you make amazing products keep it up I can't wait for my C5 components to come in and make my car an audiophiles dream !! *****

I don't have these ones I have a pair of 12W3v2-4 that I bought from a pawn shop for $100 two years ago. I have them in a ported box powered by a 1100 watt class d Sony Xplod and they pound. Now if the sub doesn't say JL on it I won't buy it.

JL Audio makes nothing but top-of-the-line equipment, and this 12w3v3 is no exception. I have two 8w3v3's in the doors of my 2005 Mustang, and those are so much better than what I was expecting as well, so I decided to get the 12" W3. I built a custom vented box made out of 3/4" MDF with double thick MDF on the front side with about ~2 cubic feet of air space. Believe it or not, I built this for Home Theater Use with a BASH 500W amp powering it, and wow. I LOVE THAT VISCERAL FEELING!! JL Audio fan for life. Thanks, SonicElectronix, for also having the lowest price!
