RSL (Rogersound Labs) Speedwoofer 12S vs Harbinger V2218S

What the RSL (Rogersound Labs) Speedwoofer 12S offers: 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. Watch for: 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.

What the Harbinger V2218S offers: Independent CEA-2010 testing records 81.7 dB at 20 Hz and 128.9 dB through 40-80 Hz. The ported, front enclosure with 18” (457mm) driver delivers formidable upper-bass output for movie effects and music. Watch for: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 825.5H x 673.1W x 754.4D mm cabinet and 40.8 kg mass still require deliberate placement and calibration.
