Same family: the Klipsch Flexus Sub 200 (larger subwoofer, estimated 3.8/5).
Pros: A compact sealed 10 inch subwoofer made to add bass to a Klipsch Flexus soundbar in a small room. Independent CEA-2010 testing records 90.2 dB at 20 Hz and 109.1 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with a 10” driver suits a small room.
Cons: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub. The 339.9H x 335.0W x 349.2D mm cabinet and 9.4 kg mass still need deliberate placement.
