Description

    This is a used product that has been professionally rebuilt here at Sundown Audio. It comes with a non-doa warranty only. That means they are guaranteed to work when you receive it but no further warranty afterwards. Let us know within 24 hours of delivery if this product has an issue. We will not warranty any used subwoofer after that time. These potentially have scratches & scuffs on the magnets/motors and will not be in new condition.

    • RMS 600 watts
    • Dual 2 or 4 ohm voice coils
    • Black Aluminum 2.5” voice coil for superior heat dissipation
    • High-temperature 4-layer copper voice coil wire
    • Stitched-on “Mini-XL” tinsel leads to prevent fatigue and failure
    • Solid pole-piece and multi-vent magnetic gap
    • Dual-magnet design for smooth acoustic response
    • Custom tooled cone shape for reduced mechanical noise over high excursion
    • Bolt-through motor design to ensure maximum longevity and ruggedness

    Sundown's SLD slim subwoofers deliver incredibly high volume through several important upgrades. These include pole-piece channels to reduce air noise and improve cooling, top-plate "slits" for better cooling and less distortion and a magnet shorting ring. Sundown has also secured the spider, motor, and aluminum pole cap with bolts, and added "mini-XL" lead wires for years of reliable service.
