Product Description

Please note AE version available till further notice


JL Audio's 30-plus years of research into car audio design has produced the legendary W7 subwoofer, and you'll hear that engineering in every note. JL Audio applies its advanced technologies separately to each W7 subwoofer, so each size sub is a unique design with its own motor and suspension system. You'll hear smooth, audiophile-quality bass output, even at extreme levels.


W7 subs feature six different patented technologies which give them their edge:

  • W-Cone™: a dish-shaped outer cone is supported by a second W-shaped inner cone attached to the the sub's voice coil structure. The light mineral-filled polypropylene cones respond rapidly for accurate, distortion-free bass without unwanted coloration.
  • OverRoll™: the oversized polyether foam surround extends over the edge of the mounting flange for more bass output without sacrificing linearity.
  • Floating Cone Attach Method (FCAM™): cone-bonding technology keeps the voice coil centered during long excursion.
  • Plateau-reinforced spider attachment: a collar on the voice coil eases stress on the spider for extended excursion and improved reliability.
  • Elevated frame cooling and cross-drilled pole-piece: cone movement pumps air through vents in the frame and machined holes in the pole piece, keeping the voice coil cool.

JL Audio designed the 3-ohm 12" W7 subwoofer to maintain linear motion during extreme cone travel, so you get a high-performance sub that's incredibly reliable. You'll find a strong cast-alloy basket and ultra-long voice coil among many impressive features which help this sub deliver profound, natural, and lifelike bass.

    1. SQ, or SPL?

      Posted by Ansalon on 3rd Jan 2011

      I gave this sub 4 stars simply because I haven't listened to everything out there. I know there are better subs. But they cost alot more money than I'm willing to spend. Now; this is, in my opinion, the best sub I've ever heard. I built a factory spec. sealed enclosure and backed it up with the JL Audio 1000/1. Beautiful sound. doesn't break up, or slow down. This sub will reproduce notes you may not have heard listening to a lesser quality sub. I'm amazed at how tight and controlled it is (sq). I'm also pretty impressed with how loud this beast can get (spl). This is a sub built mostly for bassheads, but it's engineered in such a way that anybody can listen to it. This isn't compact. I believe mine weighs 56 lbs. The box is 1" mdf. So the whole setup weighs a ton, and it won't fit into a small (Mini Cooper)car without folding or removing the rear seats. Anyways, for the price, if you can afford to power it, and that includes upgrading your electrical system, this sub is definitely worth the money.
