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

The deflectors you put up look to protrude a great deal ahead of the tweeters, I wonder if you tried this without the protrusion, with the deflector board put back to the edge of the frame where it does not interfere with the front output.

Also wondering about how far you need the back portion of the board to extend to get the full effect.

As to how far forward the board extends- do you leave it just short of intruding into the line of sight to the tweeter? When I experimented with this before, the results were very dependent on how much reflection you had from the opposing sidewall before you placed the deflector. If the opposing sidewalls were not uniform and reflective, placing the board ahead of the tweeters made less of a difference. So I proceeded largely with control of the backwave alone, without redirection of the front output away from the opposing side wall.
