Audio diffuser

@rixthetrick  from what I understand you don't need them for the back wall. That should be for absorption.  Front wall on the ceiling and at points of first reflection. What you are doing is impressive. I don't have the tools to build my own. With the trays it would be about 54 inches tall and 36 inches wide behind each speaker. All in money wise about $240.00.

And 2inches deep. Just to break up the hi frequency. 

@rixthetrick Those look like they will be great. Look forward to hearing your assessment once completed.

Looks like a great design. Like an open folded horn speaker.

@knighttodd - perhaps we understand the naming of the walls a little differently?
The front wall to me, is the wall I am facing when listening to music coming out of my speakers. The back wall is behind me, which sees the most on axis first reflection from the loudspeakers. The ceiling and floor gets a fraction of the energies the wall behind me sees. As my speakers are toed in, these waves will bounce back and forth between both the front and back walls from what I’ve read.

From what my wife and I already can hear, diffusion on the front wall behind the speakers in the working frequency range of the diffusers I have built have somehow made the bass sound more defined and faster.

I do have currently two normal diffusers that are 17" deep based upon prime number 17 and there will be four of them, replacing the strict higher frequency absorption I did have in place behind the speakers on the front wall respective to listening position. I intend on building diaphramatic carbon low frequency absorbers as well, underneath and on top of the diffusers as well as the corners. So that not just in the corners, but the top edge and bottom edges of the front and back walls have low frequency absorption.

I have to purchase a measurement system anyway, I’m currently investigating which version of Clio for the task. I’m working on flutter echo first (and yes doing it this way is a compromise, based upon both limited room size and budget) then I will have to read a whole lot more and implement some brain cells on the math to get the room sorted.

I will post results in my thread. Please do the same Knighttodd :-)
