Same family: the Sony Bravia Theater Sub 7 (smaller subwoofer, estimated 2.9/5) and the Sony Bravia Theater Sub 8 (smaller subwoofer, estimated 3.4/5).

Pros: A sealed dual 8 inch subwoofer with decent output for a mid-size room. Independent CEA-2010 testing records 98.0 dB at 20 Hz and 112.8 dB through 40-80 Hz. The sealed enclosure with (2) 8” drivers suits a mid-size room.

Cons: The 390.0H x 400.0W x 350.0D mm cabinet and 23.3 kg mass still need deliberate placement.
