Sundown Audio - SLD-12 Shallow Mount 12" Subwoofer D2/D4

Sundown Audio - SLD-12 Shallow Mount 12" Subwoofer D2/D4 The Sundown SLD series can be considered a re-boot of the SD-2 line from 2011. The SD-2 was essentially a shallow SA v1 by design meaning it shared the cone, surround, and spider with the SA but with a shorter motor with a shorter coil. The SD series went another route starting with the 3rd generation (SD-3) tilting more towards SQ and sealed enclosures (this remains true for the SD-4 series as well). Due to popular demand we created the SLD series to add a heavily abuse tolerant shallow that likes ported boxes back into the line-up!Much like the current SD-4 series we utilized solid pole-piece so the SLD can also be mounted directly against the rear enclosure wall to reduce net depth requirements. Compared to the old SD-2 we have introduced numerous important upgrades: pole-piece channels for reduced air noise & increased cooling, top-plate slits for better cooling and less distortion, and a magnet ID shorting ring.
