Room correction is something I’ve always been curious about though. I feel like I should have tighter bass with the SVS. It can be a little loose and muddy at times.
Rather than room correction (which can’t fix a standing wave in the room) consider something called a Distributed Bass Array. The idea is simple- by having multiple subs operating **below** 80Hz you can break up any standing waves in the room and thus get good bass.
If a standing wave is killing bass at the listening position(s) all room correction will do is try to put more power into that frequency. But a standing wave causes cancellation (IOW is a null point) so any amount of power you put into that frequency won’t change things.
The best DBA I know of (and one of the best subs around as a result) is the Swarm made by Audiokinesis.
