Same family: the RSL (Rogersound Labs) Speedwoofer 10E (smaller subwoofer, rated 3.3/5), the RSL (Rogersound Labs) Speedwoofer 10S (smaller subwoofer, rated 3.4/5) and the RSL (Rogersound Labs) Speedwoofer 10S MKII (smaller subwoofer, rated 3.6/5). See every RSL Speedwoofer generation.

Pros: An affordable rear ported 12 inch subwoofer with strong deep bass output for movies. Independent CEA-2010 testing records 109.3 dB at 20 Hz and 113.2 dB through 40-80 Hz. The ported, rear enclosure with 12” (305mm) driver has the headroom for demanding film bass in a large room.

Cons: The 565.1H x 479.4W x 562.0D mm cabinet and 37.2 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
