I agree that a diffused front wall reflection is better than a single strong reflection.
But... personally I care more for that exceptionally precise stereo image, resolution, dynamics and "blackness" you get from no front wall reflection. Yes - a little front wall reflection will sound bigger, but I dont like it. I have worked hard to get it below -30 dB, where its not audible anymore.

hi Stig,

what are the depths of the various 1" squares in your diffuser panels?

cheers Stig,

I hoped that the various depths would be between 4 inches max to 1 inch. There is no way I could disguise that as a funky kind of wall covering, LOL.

I wonder if some of the 3s and 4s could have part of their depth hidden behind the 2s. This would make for a panel around 150mm deep. more complicated, but I might get away with it.

You can of course reduce the total depth, but that would affect the bandwith of the diffusor at low frequencies. Of you make all coloums half of what they are in my diagram, lower cut-off will be one octave higher, or approx 1150 Hz.

Ok, here's the last update, and it might be the very last thing I do with this system.

The news are:
Hypex Ncore amps - two driving the RD-75 ribbons, and four driving the woofers - and now there's sixteen of them.... a few pics without front grilles on the woofers below.

I can't see the system there are woofers standing in front of it.

The wall of bass.

There is no such thing as too much overkill!
