Question..... within reason can one have too much diffusion On the front wall in a two channel audio room?

Bass traps are DYI and offer no diffusion. A mistake I made when I built them.

My front wall is only 11 ft wide.

Hi, I'm running GIK absorbers and bass traps on front wall, the sound suffers a little without them. Considering moving to something like Acustica Applicata Daads or Stillpoints Apertures which offer a combination of diffusion and absorption.

On the front wall I prefer absorption panels with some kind of limiting reflecting front plate. The Alpha panels from GIK are very good for the price. I much prefer Apertures though. Apertures, although silly money, sound the best to me on the front wall and all reflection points. I have tried a bunch including pure absorption, pure diffusion and various mixes.

There is no right or wrong, experimentation is the only way. Buy a few panels of a different type and give them a try.

A mix of diffusion, bass trapping, and broadband absorption. I'm considering adding some more diffusion though- in the form of scatter plates on the fronts of the two broadband absorption panels.

Advanced, how do you set up your Apertures?
Tima has been running his room with vertical columns of two panels on the front wall: central and maybe 3' to the R and L, so six Apertures in total on front wall; and at side wall first reflection points.

I like 2 at each reflection point. I have experimented at the front wall and would agree 6 there. I need to buy more but may build my own.

So, two vertically on midline front wall. How close to those would the columns R and L be? Simple matter of experimentation?

For me, I use the panels to cover windows but they are symmetrical. LR about 24” away from center. So no experimentation. I would say because of those windows, treatments at the front of the room are more important for me than they might be for someone with a solid wall.

Too much diffusion causes confusion. But it doesnt look like you have too much
