JL Audio 12" W3 Series Mobile Subwoofer, Model 12W3V32
Clearly the best sounding W3's yet, these subwoofers feature DMA-optimized, long linear excursion capability to minimize distortion and increase output. W3v3's are available in single 2 ohm, 4 ohm and 8 ohm versions and are superb performers at medium power levels in compact sealed or ported enclosures. Multiple patented technologies enhance performance and reliability. As with JL Audio’s flagship drivers, development was guided by JL Audio’s proprietary DMA (Dynamic Motor Analysis) modeling system to deliver outstanding dynamic stability and low-distortion operation within their intended power envelope. A mineral-filled polypropylene upper cone body with a metallic JL Audio logo medallion provides a classy new look, while a removable (and customizable) mounting flange trim ring receives grille-mesh inserts directly, without the need for additional grille hardware.
- DMA Optimized Motor System
DMA-optimized motor systems deliver highly consistent motor force over a long range of stroke and input power levels.
- Elevated Frame-Cooling
(U.S. Patent #6,219,431) Creates a pathway for high-velocity air to flow directly across the top-plate and onto the voice coil.
- Vented Reinforcement Collar
(U.S. Patent #5,734,734) JL Audio’s patented Vented Reinforcement Collar (VRC™) improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance.
- Floating Cone Attach Method (FCAM™)
(U.S. Patent #6,501,844) Allows the cone and surround to be aligned independently of the spider/coil assembly, improving pistonic motion.
- Insert Molded Suspension / Coil / Terminal Sub-Assembly
(Patent Pending) Ensures precise lead wire length, lead wire entry and exit angles and coil to spider perpendicularity.
- Surround Stress-Relief
(Patent Pending) Promotes smooth, consistent surround behavior at all excursion levels.
- Customizable Trim Ring
(U.S. Patent #D480,709) This removable ring accepts optional grille mesh inserts directly and can be painted to match the installation theme.
