Short answer: the Kef T2 if sound quality matters most, the Revel B8 if price matters most. The Kef T2 ranks #19 of 42 subwoofers at $719.99. The Revel B8 ranks #20 at $500, $219.99 cheaper.
What the Revel B8 offers: Independent CEA-2010 testing records 48.7 dB at 20 Hz and 105.5 dB through 40-80 Hz. The sealed enclosure with 8” (203mm) driver is best suited to upper-bass support in a modest room. Watch for: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects. The 353.1H x 266.7W x 266.7D mm cabinet and 9.0 kg mass still need deliberate placement and calibration.
What the Kef T2 offers: Independent CEA-2010 testing records 84.6 dB at 20 Hz and 105.7 dB through 40-80 Hz. The sealed enclosure with 10” (254mm) driver is best suited to upper-bass support in a modest room. Watch for: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects. The 381.0H x 370.8W x 177.8D mm cabinet and 2.7 kg mass still need deliberate placement and calibration.
Buy the Revel B8 if the price is the priority over sound quality, or the Kef T2 if sound quality is the priority over the price.
