Pros: A small sealed subwoofer that adds a little bass support to compact speakers without a full size cabinet. Independent CEA-2010 testing records 89.2 dB through 40-80 Hz. The sealed enclosure with 6.5” (165mm) driver is intended to add useful bass support without a full-size cabinet.
Cons: Without a published 20 Hz output result, deep-bass capability is less certain than its midbass figure. The 241.3H x 215.9W x 266.7D mm cabinet and 6.8 kg mass still need careful placement and calibration.
