Short answer: the RSL (Rogersound Labs) Speedwoofer 10E. It ranks #183 of 212 subwoofers by sound quality, rated 3.3/5, at $339.34; the Klipsch Reference R-101SW ranks #194, rated 3.2/5, and costs $379.99, so there is not much of a tradeoff to weigh.
The case for the RSL (Rogersound Labs) Speedwoofer 10E: Independent CEA-2010 testing records 94.0 dB at 20 Hz and 107.3 dB through 40-80 Hz. The catch: The boxy cabinet skips the rounded edges of pricier subs in the lineup.
The case for the Klipsch Reference R-101SW: Current 10-inch Reference subwoofer replacing the R-100SW and Klipsch R-10SW. The catch: Compact cabinet and 150W amplifier limit sustained ultra-low infrasonic output below 30Hz compared to larger 12-inch or 15-inch subwoofers.
Buy the RSL (Rogersound Labs) Speedwoofer 10E. It is rated higher for sound quality than the Klipsch Reference R-101SW and costs less, so only choose the other one for a particular feature it does better.
Worth knowing: the Klipsch Reference R-101SW has not been measured yet. Its rating is estimated from related models, with a likely range of 3.0 to 3.4, so treat this verdict as provisional.

Klipsch Reference R-101SW: $379.99 each Estimated Amazon eBay
Older models: the Klipsch R-10SW (rated 3.2/5) and the Klipsch R-100SW (estimated 3.2/5). See every Klipsch Reference subwoofers generation.
Same family: the Klipsch R-121SW (larger subwoofer, ranked higher, rated 3.6/5).
Pros: Current 10-inch Reference subwoofer replacing the R-100SW and Klipsch R-10SW. Features a redesigned 10-inch front-firing spun-copper TCP (thermoformed crystalline polymer) woofer with improved cone stiffness and smoother crossover transitions, powered by an all-digital Class-D amplifier delivering 150W RMS (300W peak). Utilizes a rear-firing aerodynamic slot port in an MDF cabinet to reach a rated 29.5Hz extension (-3dB) and 115dB peak acoustic output. Includes low-pass crossover, phase switch (0/180), and line-level/LFE RCA inputs.
Cons: Compact cabinet and 150W amplifier limit sustained ultra-low infrasonic output below 30Hz compared to larger 12-inch or 15-inch subwoofers. Standardized ground-plane CEA-2010-A burst measurements have not yet been published.
