Short answer: the Bose Lifestyle Ultra Subwoofer. Both are rated 3.8/5 for sound quality (#50 and #73 of 212 subwoofers), and the Bose Lifestyle Ultra Subwoofer costs $849 against $899.99 for the Klipsch RP-1200SW, so with nothing between them on sound quality, price settles it.
The case for the Bose Lifestyle Ultra Subwoofer: Independent CEA-2010 testing records 90.6 dB at 20 Hz and 115.4 dB (avg of 3/4 bands) through 40-80 Hz. Watch for: The 326.8H x 294.7W x 294.7D mm cabinet and 33.7 lbs (15.3 kg) mass still need deliberate placement and calibration.
The case for the Klipsch RP-1200SW: The sweet-spot 12-inch model in Klipsch’s Reference Premiere subwoofer series. The catch: A heavy, deep enclosure (31.1 kg, 598 mm deep) that demands meaningful floor space.
Buy the Bose Lifestyle Ultra Subwoofer. Both are rated the same for sound quality, and it costs $50.99 less than the Klipsch RP-1200SW.

Pros: Independent CEA-2010 testing records 90.6 dB at 20 Hz and 115.4 dB (avg of 3/4 bands) through 40-80 Hz. The ported enclosure with a 12” driver is well suited to a mid-size room.

Klipsch RP-1200SW: $899.99 each Amazon eBay
Same family: the Klipsch RP-1000SW (smaller subwoofer, ranked lower, rated 3.6/5), the Klipsch Reference Premiere RP-1400SW (larger subwoofer, estimated 4/5) and the Klipsch RP-1600SW (larger subwoofer, rated 4.2/5).
Pros: The sweet-spot 12-inch model in Klipsch’s Reference Premiere subwoofer series. Delivers 400W RMS / 800W peak power driving an ultra-long-throw 12-inch front-firing Cerametallic woofer through a front Aerofoil slot port. Audioholics comprehensive CEA-2010 bench testing proved class-leading output across the sub-bass spectrum, producing 105.8dB at 20Hz and over 117dB above 40Hz with remarkably low harmonic distortion. Rivals established internet-direct heavyweights like SVS and Monolith in clean output capability.
Cons: A heavy, deep enclosure (31.1 kg, 598 mm deep) that demands meaningful floor space. Lacks app-based parametric EQ or DSP presets found on competitors like SVS Pro models.
