Product Details

JL Audio 8" Subwoofer Driver, Model 8W04

The 6W0 and 8W0 subwoofers operate in very compact enclosures and feature long excursion capability and patented VRC?technology. Rubber sealing gasket / grille receiver (grilles sold separately). Single voice coil. The 18W3’s are superb performers in sealed enclosures and are also well-suited for ported designs. High power handling, dual voice coils, very long excursion capability, patented VRC+?technology.

Features:

  • DMA Optimized Motor System
    DMA is JL Audio’s proprietary Dynamic Motor Analysis system and is aimed at improving dynamic motor behavior. As a result of DMA optimization, 18W3 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. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass
  • Vented Reinforcement Collar
    Further enhances cooling by forcing air to flow across the top of the voice coil. The VRC also reinforces the critical cone/spider/voice coil joint, resulting in superior mechanical integrity
  • Radially Cross-Drilled Pole-Piece
    This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former and works in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil. This improves power handling and reduces power compression effects, leading to more linear performance
  • PowerBump
    The PowerBump™ backplate design provides exceptional mechanical clearance for the voice coil at high excursions
