Product Details

JL Audio 12" Mobile Subwoofer, Model 12WX4

WX Subwoofer Drivers
Built from the same DNA as the rest of the JL Audio subwoofer lineup and dedicated to the proposition that real value can only exist when real performance is delivered.

Like all JL Audio subwoofer drivers, the WX's are centered on a long excursion, DMA-optimized motor system, supported by our patented Elevated Frame Cooling and a highly linear suspension. This means they deliver lots of low-distortion, high-quality bass with all types of music.

WX's are ideally suited for lower power applications and offer a powerful combination of performance, value and installation attributes.

You simply won’t believe you’re listening to our least expensive subwoofer drivers!


  • DMA Optimized Motor System
    Highly optimized motor system delivers linear motor force over a wide range of excursion and power levels to reduce distortion.
  • Great Bass in Small Enclosures!
    For maximum application flexibility, WX's are designed for use in compact sealed or medium-size ported enclosures.
  • Elevated Frame-Cooling
    Creates a pathway for high-velocity air to flow directly across the top-plate and onto the voice coil.
  • We make it easy to protect your investment.
    WX's are designed to directly receive JL Audio's protective grille mesh inserts (sold separately).
