How will it fill your room?
Where you sit (optional) find the spot where the bass is most even at your seats
"How deep it goes" is the manufacturer's low-frequency figure (17 Hz, 12″ driver); brands measure it in different ways, so compare models within a brand with more confidence than across brands. Room bass notes are calculated from your dimensions for a closed rectangular room — open plans and doorways shift them. Subwoofer placement and your receiver's room correction smooth out most peaks and dips. Want help with placement? Ask us.

How many subwoofers does my room need?
One sub covers about 1,000 cu ft with an 8″ driver, 1,800 with 10″, 2,800 with 12″, 4,000 with 14″ and 5,500 with 15″ and up. A 22 × 15 × 10 ft room (3,300 cu ft) suits two 12″ subs; two are also preferred for more than one row of seats.
Where should the subwoofer go?
It depends on the room: the “Where you sit” option works it out from a room model of your dimensions and seat. It is a starting position, not a measurement — the final spot is found on site with a sub crawl.
Every figure here is an estimate from the manufacturer's published specifications and standard room acoustics. Planning a full room? Plan my home theatre · Check compatibility
