Pros: Step-up 12-inch sealed subwoofer in the Onkyo-collaborated Flexus ecosystem. Features a 12-inch high-excursion paper cone driver powered by a 200W RMS / 400W peak Class-D amplifier, reaching a rated 26Hz low-frequency extension and 107.5dB maximum output. Connects wirelessly to Flexus soundbars via 2.4GHz Klipsch Transport technology with ultra-low latency, supports dual-subwoofer pairing to smooth out room modes, and includes a standard mono RCA LFE input for wired integration.

Klipsch Flexus Sub 100: $279.99 Amazon eBay
Pros: 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.
