I have the same problem - lovely wide soundstage but it lacks depth (compared to my last listening room. I suspect because, like yours, my panels are too close to the wall.

Sure there are many things you can use to diffuse the rear wave (and diffusion is what is required, IMO - not absorption). So what I am thinking of doing is creating a lattice out of 1"D bamboo poles and fixing this to the wall (which in my case is sloping :-(( ). It will run up to about 7' high and span to the outside of the panels - so about 10' wide.

The gaps between the lattice will be 1.5 - 2" square. If it delivers the soundstage depth I want ... then I can get the required WAF approval by painting the poles to match the walls.

I have a COLLECTION of about a DOZEN Pool Noodles in 4" diameter. I tried making an 'array' in a PHi Shape 'arc' which is like a 'section' of snail shell. maybe 30 or 40 degrees or arc. I used PVC and ingenuity. PVC did NOT go up thru the center of the Noodles.
I'll revisit that LATER.

Another test would be using the famous 'Fake Fikus'. This would be expensive at the density needed AND take up lots of floor space. Nope, I'll try other stuff

A FLAT array of bamboo is NOT correct. That automatically limits frequency and 'regularizes' the dispersion pattern, and to only the horizontal plane AT THAT.
In short, presenting the panel with variable spacing and distance of elements of an otherwise regular array will provide a spread of frequency response. the pattern will remain horizontal.
Building to a 'rule' should facilitate that goal.

Too much is never enough

  I thought AndyR was going to do overlaid vertical and horizontal lattice. You are bringing up a good point though about wanting not to make the intervals too regular - perhaps use QRD tuning for each axis for width rather than depth.

    I think it is a good suggestion of pictureguy's to make the spacings irregular.
