The Resilient Sounds RS 12″ D4 – 500w RMS Subwoofer wasn’t built to be your average budget driver. Instead we went above and beyond with our entry level RS-12 and RS-15 featuring 3” 4 layer VC, triple stacked nomex spiders, and a 130 oz motor! This series will also include the RS-8 which features dual stacked nomex spiders and a 100 oz motor. The RS Series is rated 500 watts rms / 1000 watts peak for all models.

Old Stock – older equipment that has been “pushed to the back” of the pile for a while. Clearing out to make room for new. May contain dust, damaged packing, etc.
