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

Posted by josh358 on March 3, 2017 at 04:56:01:
I don't think he said but according to the dimension on the diagram, the adjacent should be roughly 68" and the opposite 35", so that would be about +/- 27 degrees or basically the standard Blumlein equilateral triangle.

I assume the reason you want them closer in an ambiophonic setup is the HRTF? This is a practical issue for me since I have a projector and can't put my speakers at the recommended angle.

Your system must sound pretty spectacular, what with the Sound Labs and ther controlled directivity! I tried some of the sample recordings on the ambiophonics site last night with the backwave barriers in place and was surprised that I got a lot of the effect since I was listening at +/- 30 degrees. Not a 180 degree spread, but definitely outside the speakers and the sense of three dimensionality that I've heard from ambiophonics in the past, with sounds vastly in the distance or right up to the speakers depending. It was rough -- occasional buzzing and a hole in the middle -- but it was impressive nonetheless, particularly since my earlier ambio experiments with Maggies have failed.
