Monoprice Monolith 16 THX Ultra vs Funk Audio Ultra 24.0

What the Monoprice Monolith 16 THX Ultra offers: 16-inch ported driver and THX Ultra certification deliver 126.5dB CEA-2010-A average at a fraction of the price of the subwoofers ranked above it. Watch for: Heavy at 78 kg and ported design can interact with room acoustics.

What the Funk Audio Ultra 24.0 offers: Published CEA-2010 specifications list 120.0 dB at 20 Hz and 127.9 dB through 40-80 Hz. The sealed enclosure with 24” (610mm) driver has the headroom for demanding film bass in a large room. Watch for: The 787.4H x 660.4W x 609.6D mm cabinet and 135 kg mass make this a serious placement and moving commitment. A sealed cabinet still needs careful placement and calibration to avoid room-mode peaks.

Buy the Monoprice Monolith 16 THX Ultra if the price is the priority over sound quality, or the Funk Audio Ultra 24.0 if sound quality is the priority over the price.
