Short answer: the Edifier T5s. It ranks #2 of 73 subwoofers by sound quality, rated 3.8/5, at $199.99; the Klipsch Flexus Sub 100 ranks #22, rated 3.4/5, and costs $349, so there is little reason to consider the other one.
The Edifier T5s is the better-sounding choice. An affordable ported 8 inch subwoofer with strong output for its size, a good bass upgrade for a small to mid size room. Watch for: The 400.0H x 398.8W x 169.9D mm cabinet and 22.9 lbs (10.4 kg) mass still need deliberate placement and calibration.
The case for the Klipsch Flexus Sub 100: A compact sealed 10 inch subwoofer made to add bass to a Klipsch Flexus soundbar in a small room. The tradeoff: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub.
Buy the Edifier T5s. It is rated higher for sound quality than the Klipsch Flexus Sub 100 and costs less, so only choose the other one for a particular feature it does better.
