When I say mono, I mean when both stereo speakers play the same bass and mid-bass frequencies.


"Center" doesn't have to be forward and physically large, and there are any number of reasons why this might occur that have nothing to do with combing. In fact, any significant combing *artifacts* would be well into mid.s and upper mid.s (depending on loudspeaker separation).

As a test you could always try a 2 channel setup where you have experienced this problem before, and then "cut" the response above 400 Hz and see if it's still a problem. If it is, it's not an artifact from combing (..provided the loudspeakers aren't too far apart).

Yes, the reason you get a boost at lower frequencies is because the wavelengths get larger and larger, they wrap around the head and hit both ears where as in the stereo triangle, the higher the signal is in frequency, the less the sound wraps around the head and only hits 1 ear.
So there is a mismatch in amplitude. The transition where ILD is dominate is around 700Hz.

Another interesting thread.

I assume by RACE you mean this?

Ambio4YOU - Ambiophonic DSP | Ambio4YOU systems


I hadn't come across it before so had to Google. I'm familiar with Michael Gerzon's work on ambiosonics

Ambisonic Info | Home

but ambiophonics is new to me.
