#77 Harbottle Audio C18 L1: $5,331.56 eBay
Pros: Published CEA-2010 specifications list 108.0 dB at 20 Hz and 118.5 dB through 40-80 Hz. The ported enclosure with 18” (457mm) driver has the headroom for demanding film bass in a large room.
Cons: The 670.1H x 578.1W x 460.0D mm cabinet and 39.0 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential.
How it compares: Just above it: Velodyne Acoustics DD-15+ - $532 cheaper. Just below it: HSU Research VTF-15H - $4133 cheaper.
