What happens when you put a loudspeaker in a corner?

...they become eight!

Virtual Quadraphonic!

That would explain the "congested" sound.

Hi:

Corners are some of the worst places to get a stereo image, besides of a horrible reinforcement of bass tones.

Except if you place them further from the corners the difference from the reflections will be larger and more out of phase. You choose

Well, I don't think the idea is to put full-range speakers there, but subwoofers. Doing so will give 8 times the free field sound pressure, or +18 dB.

Actually, no, this is stuff that I use when I teach. It is so much easier to understand the 7 mirror sources when you see them in mirrors like this.

There's little more rewarding in this life than confusing kids

Have you tried sitting up against the back wall?

Greets!

Hmm, each time you halve the radiation angle yields a doubling of SPL, or +3 dB, so if a sphere has a Q = 1, then a corner will have a Q = 8, or 10*log10(8) = ~ +9.03 dB, so the Directivity Index (DI) = 9.03. Since speakers are normally rated in half space though, max theoretical corner gain is only 10*log10(4) = ~ +6.02 dB.
