Miramar, FL — Since 1993, JL Audio W6 subwoofers have consistently defined bass excellence in small enclosures. In 2002, the original formula reached a new level with the W6v2's, which have had a remarkable ten-year run as go-to drivers for quality-focused installations.
For 2012, JL Audio is introducing the W6v3's with a slew of advances, representing two years of intense effort from the company's engineering department. These upgrades generate very noticeable performance increases in the form of greater output, sharper dynamics and improved overall sound quality.
The hearts of the W6v3's are their motor systems, featuring larger field plates and magnet assemblies than those used on v2's. These more powerful motor systems have been critically refined via JL Audio's proprietary DMA system to deliver exceptional linear excursion and dynamic stability. Further enhancing performance is a new motor cooling circuit design, featuring a patented pole vent designed to improve cooling efficiency and reduce power compression. The voice coil configuration remains a dual 4 ohm design with a terminal jumper system to allow parallel or series wiring.
New suspensions feature a wide rubber surround and a new progressive-roll spider to control the increased excursion capability. The cones are also new, and include a silver accent ring that creates a classy new look in combination with the satin black cast alloy basket.
W6v3's are ready for another decade of sound quality dominance.
