#81 Outlaw Audio Ultra-X13: $1299 Discontinued eBay
Pros: Independent CEA-2010 testing records 109.8 dB at 20 Hz and 118.1 dB through 40-80 Hz. The ported, bottom enclosure with 13” (330mm) driver has the headroom for demanding film bass in a large room.
Cons: The 635.0H x 457.2W x 584.2D mm cabinet and 47.6 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.
How it compares: Just above it: SVS SB13-Ultra - $500 more. Just below it: REL Acoustics HT/1510 Predator II - $1228 more.
