JL AUDIO 13W7

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 13.5" dual voice coil 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 coils among many impressive features which help this sub deliver profound, natural, and lifelike bass. This 1.5-ohm DVC sub should be matched with the proper amplifier and wiring to ensure optimum performance.
