Short answer: the Magico Audio ASUB. It ranks #137 of 143 subwoofers by sound quality (rated 3.6/5) at $9,000 and is still sold new; the Genelec HTS4B ranks #139 (rated 3.4/5) and is discontinued, so it is only an option used.
The case for the Genelec HTS4B: A 12 inch passive radiator subwoofer with XLR and RCA inputs and a link output, now discontinued. 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 case for the Magico Audio ASUB: A compact luxury sealed 10 inch subwoofer with XLR and RCA inputs plus a through output. The tradeoff: 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.
Buy the Magico Audio ASUB. It is rated higher for sound quality, and the Genelec HTS4B is discontinued, so it is only available used.
