RE: Another First Reflection Trap (FRT) Adventure : Quasi-Ambiophonics

"Just a word of caution here. Ideally, the main speakers should be line array type. So it is possible that you are right."

I think I may have made a mistake by using the central axis as a guideline. At 3 kHz, a wavelength is only about 4", so relative phase loses significance. There would still be an intensity difference that in theory needs crosstalk cancellation, but I don't think it can really be done effectively at that frequency since even a 2" head shift will change the effect from cancellation to reinforcement. So I plan to try again with the midrange as the baseline, and also with the software although I'm currently building a new HTPC so it will be a few days before I can try that.

Wow, huge difference in the sample! I'm just listening on cheap earbuds now, I'll head upstairs at some point tomorrow and find my Etymotics. But it's obvious even with the cheap earbuds. No wonder you're enthusiastic. How have you positioned the convolution speakers?
