The RSL Speedwoofer 10S MkII is a powered, ported subwoofer built around a 10-inch cast-frame woofer and RSL’s rear-vented Compression Guide tuning. Its XDR Class D amplifier is rated at 400 watts RMS and 1,020 watts peak. Selectable DSP modes provide LFE operation for deeper low-frequency extension and Music operation tuned to match the original Speedwoofer 10S’s response, with improved power and dynamics. The subwoofer also includes a built-in receiver for RSL’s optional wireless transmitter.
