Short answer: the SVS 3000 Micro on measured sound quality, the Klipsch Flexus Sub 100 on price. The SVS 3000 Micro ranks #6 of 73 subwoofers, rated 3.7/5, at $799. The Klipsch Flexus Sub 100 ranks #22, rated 3.4/5, at $349, $450 cheaper.
The SVS 3000 Micro is the better-sounding choice. A tiny sealed subwoofer with two opposing 8 inch drivers, small enough to tuck beside furniture while adding upper bass weight. 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.
What the Klipsch Flexus Sub 100 does well: A compact sealed 10 inch subwoofer made to add bass to a Klipsch Flexus soundbar in a small room. The catch: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub.
Buy the SVS 3000 Micro when sound quality outweighs the price for you, and the Klipsch Flexus Sub 100 when the price outweighs sound quality instead.
