Short answer: the SVS 3000 Micro. It ranks #6 of 73 subwoofers by sound quality (rated 3.7/5) at $799 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 3000 Micro is the better-sounding pick. A tiny sealed subwoofer with two opposing 8 inch drivers, small enough to tuck beside furniture while adding upper bass weight. The catch: 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.
Why pick 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 3000 Micro. It is rated higher for sound quality, and the Klipsch HD Theater 600 is discontinued, so it is only available used.
