Audio diffuser

Am I wrong in thinking those stands look short. Typically mini monitors are elevated to ear level when sitting. Are they? Perhaps you have experimented with different heights.  

Update on the install. I installed 8 of the 2" deep wood trays. 4 on each side behind speakers.  4 more, 2 on each side of the back wall.  There is a decent amount of reduction in  treble glare that I was experiencing with some music. Overall it has smoothed out the room and the bass seems much more clear. Very easy to install. Inexpensive and well worth it for high-end glare. My system consists of  Lumin u1 mini with sbooster, Roon Nucleus, AR Ls28se, Audio GD r7he mkii dac, Tyler Acoustic Halo Extrem speakers and 2SVS pb300 subs. Prima Luna Evo 400 Amp. My system and room has been 2 years in the making and this is the best so far. 

I'll bet the angle of deflection behind the speakers will also vary the affect.  Straight on versus 25 degrees angle in/out, 40 degrees angle in/out.  Also, the run direction, are the slats vertical or horizontal?

I've seen where the slats are converging with some commercially available treatments.  Actually, one of the best and most surprising behind transducers material I've ever experienced was a solid brick wall.  Evidently, the porosity of some brick diffuses signals well.

Im not sure why I haven’t hears about diffusion effecting bass response until now.  I wonder if the diffusors are scattering bass waves and reducing nodes and lulls as a result.

Anyhow, those diffusors are awesome!  Good job,  

Im thinking about buying a bunch of T1 diffusors today actually!
