Same family: the Paradigm Defiance V8 (smaller subwoofer, estimated 3.2/5), the Paradigm Defiance V10 (smaller subwoofer, ranked lower, estimated 3.4/5), the Paradigm Defiance V12 (smaller subwoofer, ranked lower, rated 3.6/5), the Paradigm Defiance X10 (smaller subwoofer, ranked lower, rated 3.7/5) and the Paradigm Defiance X15 (larger subwoofer, rated 4.2/5). See every Paradigm Defiance generation.

Pros: A moderately sized 12 inch subwoofer with powerful, low distortion bass and room correction, now discontinued but worth buying used. The 12 inch ported driver has a 650W RMS (1300W peak) amplifier and is rated 20 to 230Hz within 3dB. Measured output averages 119.2dB from 40 to 80Hz and still reaches 95.5dB at 20Hz, strong for a cabinet this size. It includes ARC room correction with a microphone and ART surround, plus an adjustable 30 to 120Hz crossover.

Cons: At 28.1kg and 494 x 457 x 494mm it is heavy and takes real floor space for a 12 inch sub. Output at 20Hz is 95.5dB, so the lowest effects are quieter than the output above 31Hz. It is discontinued, so you must buy used, and it was expensive when sold.
