Interesting. Reminds me of the Jecklin disk.

The main difference being that the above is made out of a soft, absorbent material, while your FRTs are solid and reflective.
Have you thought of or tried using a soft, absorbent material?

@DreamOperator:
The point of the panels isn't to absorb sound - it's to deflect reflections so the time they take to reach the LP is greater than 10 milliseconds - actually it's longer for a lot of these. That way, the essential character of planars is maintained, vice turning them into a very large pair of mini-monitors.

I see what you're saying. I'd like to try this sometime.
@DreamOperator:
Go for it! It's a real cheap experiment, and it really cleans up already good sonics!

I have some 4'x2'x4" fiberglass panels with solid wood on one side.
I took a pair of them and placed them as to block the left tweeter from the right ear and vice versa. Wood side facing the closest speaker.
While the rear reflections were not altered and there was a ton of absorption going on in the middle, I was able to get some sense of the effect. Lots and lots of depth and very clean separation.
Perhaps I'll play around more down the road. Thanks for sharing.

De Nada; I see posting here as a way of publishing findings, with the hope of getting them "peer reviewed". So thanks for filling in that part.
I just realized there might be a far less intrusive way of accomplishing the "ambio" trick. Need to make another trip to the hardware store, which might only happen in the next week or so... Would be great to increase the WAF factor from the imaginary number the current FRT configuration currently has!
