Short answer: the SVS SB-1000 PRO. It ranks #4 of 73 subwoofers by sound quality (rated 3.7/5) at $599 and is still sold new; the Klipsch HD Theater 600 ranks #35 (rated 3.3/5) and is discontinued, so it is only an option used.
The SVS SB-1000 PRO is the better-sounding pick. A compact sealed subwoofer with tight bass and huge output for its weight, best for music and small rooms. The catch: As a sealed box it gives up output in the deepest octave: 91dB at 20Hz and 97.7dB at 25Hz, where a ported subwoofer like the RSL (Rogersound Labs) Speedwoofer 10S MKII reaches 100dB and 105dB.
The case for the Klipsch HD Theater 600: A discontinued compact ported 8 inch subwoofer that adds midbass support to a small home theater system. The catch: Without a published 20 Hz result, deep-bass capability is less certain than the midbass figure.
Buy the SVS SB-1000 PRO. It is rated higher for sound quality and still sold new, while the Klipsch HD Theater 600 is discontinued.
