600 Watts RMS/1200 Watts Peak 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.
