Same family: the Paradigm Defiance V8 (smaller subwoofer, estimated 3.2/5), the Paradigm Defiance V10 (smaller subwoofer, estimated 3.4/5), the Paradigm Defiance V12 (smaller subwoofer, rated 3.6/5), the Paradigm Defiance X10 (smaller subwoofer, rated 3.7/5) and the Paradigm Defiance X12 (smaller subwoofer, rated 4.1/5). See every Paradigm Defiance generation.
Pros: A 15 inch ported subwoofer with strong, deep bass for movies in a large room, a solid value pick used. Independent CEA-2010 testing records 109.2 dB at 20 Hz and 122.9 dB through 40-80 Hz. The ported, bottom enclosure with 15” (381mm) driver has the headroom for demanding film bass in a large room.
Cons: The 625.3H x 588.8W x 625.3D mm cabinet and 41.7 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential. Discontinued.
