Short answer: the Klipsch SPL-100. Both are rated 3.8/5 for sound quality (#80 and #74 of 212 subwoofers), and the Klipsch SPL-100 costs $399 against $470.53 for the Klipsch Flexus Sub 200, so with nothing between them on sound quality, price settles it.
Why pick the Klipsch Flexus Sub 200: Step-up 12-inch sealed subwoofer in the Onkyo-collaborated Flexus ecosystem. The tradeoff: Sealed enclosure prioritizes transient speed and compact footprint over high-SPL output in large open rooms.
The case for the Klipsch SPL-100: The 10” model of Klipsch’s SPL series, sharing the measured Klipsch SPL-120’s front-firing slot port and copper-spun Cerametallic woofer design with a 200W (450W peak) amplifier. Watch for: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Klipsch SPL-120, which reached 119.7dB in the 40 to 80Hz CEA-2010 bands.
Buy the Klipsch SPL-100. Both are rated the same for sound quality, and it costs $71.53 less than the Klipsch Flexus Sub 200.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Klipsch Flexus Sub 200 3.6 to 4.0; Klipsch SPL-100 3.5 to 4.0). Treat this verdict as provisional.

Klipsch Flexus Sub 200: $470.53 each Estimated Amazon eBay
Same family: the Klipsch Flexus Sub 100 (smaller subwoofer, rated 3.4/5).
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.
Cons: Sealed enclosure prioritizes transient speed and compact footprint over high-SPL output in large open rooms. Independent ground-plane CEA-2010 burst output data has not yet been published to verify distortion limits.

Klipsch SPL-100: $399.00 Estimated Amazon eBay
Same family: the Klipsch SPL-120 (larger subwoofer, ranked higher, rated 4.1/5).
Pros: The 10” model of Klipsch’s SPL series, sharing the measured Klipsch SPL-120’s front-firing slot port and copper-spun Cerametallic woofer design with a 200W (450W peak) amplifier. Klipsch rates it to 27Hz, and the front port lets it sit close to a wall.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Klipsch SPL-120, which reached 119.7dB in the 40 to 80Hz CEA-2010 bands. The smaller woofer and half the amplifier power mean less output, especially in the deepest octave.
