JL Audio CP210G-W1v2-D4 Ported PowerWedge™ enclosure with two 10" W1v2 subwoofers

Features

Overview: This JL Audio PowerWedge subwoofer enclosure is designed around JL Audio's W1v2 subwoofers, delivering tight, powerful bass. The PowerWedge enclosure is properly sized and tuned to the optimum ported alignment for the two mounted 10" JL Audio W1v2 woofers and wired for a 4-ohm load.

PowerWedge Enclosure: The PowerWedge enclosure features solid V-groove MDF construction with internal bracing to ensure structural integrity. The PowerWedge enclosure features a Flared Slot-Port Design. The ported enclosure employs oversized slot-ports with flared exits to minimize turbulence and improve linearity at higher power levels. The W1v2 PowerWedge enclosure is finished in high-grade automotive gray carpet and features a steel-mesh grille to protect the loaded JL Audio W1v2 woofer. The JL Audio PowerWedge enclosure features a pair of gold-plated 5-way binding posts on the left and right side of the box. The enclosure is wired to provide a 4-ohm load at its speaker terminals.

10" W1v2 Woofers: The JL Audio PowerWedge subwoofer enclosure features two mounted, front-firing 4-ohm 10" JL Audio W1v2-series woofer:

• Woofer Material: JL Audio W1v2 subwoofer features an injection-molded, metallic-finish polypropylene cone woofer with an embossed metallic JL Audio logo with a butyl rubber surround for added durability, woofer excursion and bass response.
• Surround Stress Relief: By creating a radius feature on the edge of the cone, stress is relieved from the surround material at  maximum forward excursion, resulting in longer life and more consistent surround behavior.
• Interlocking Cone & Dust Cap: The W1v2's utilize a dust cap that is not just glued, but also interlocks with features molded into the cone body for a tight snap-fit. This creates a more rigid cone assembly and a more reliable dust cap attachment.
• Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W1v2 motors remain linear in motor force over a very long range of excursion, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
• Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
• Vented Reinforcement Collar: The Vented Reinforcement Collar (VRC) is a composite structure that addresses two issues related to reliability. By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weakness. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes. The VRC also features slots that facilitate air flow directly onto the voice coil windings. This reduces thermal compression effects and enhances reliability.
• Insert Molded Suspension/Coil/Terminal Sub-Assembly: The W1v2 features a unique spider, coil and terminal subassembly which is assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity. This type of assembly ensures precise lead wire length, lead wire entry and exit angles; and coil to spider perpendicularity.
• Elevated Frame Cooling System: The elevated frame design of the W1v2 delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.
