Home Speaker Asylum

General speaker questions for audio and home theater.

Measure and EQ?

Assuming the floor itself isn't resonating, and the boom is due to phase reinforcement from the room dimensions, you could identify the problem frequencies with a test disc and SPL meter (or an RTA if available), and apply parametric EQ to cut power to the frequencies that boom. Or use a system like Audyssey that does both.

There will probably also be response dips from phase cancellation at certain frequencies, but those are harder to fix. Just throwing more power at them will mostly strain your amp and speakers, since it's still a subtractive phenomenon.
