where to put 2 diffusors

[maestro]

My room is long 14ft and 12.75ft wide. Height 8ft. Will be used for tracking and mixing

I have

a) Mondo trap in each of the 4 corners
b) 2 Tri corners on the North corners
c) 2 Standard Minitraps for the South corners and 1 for the south ceiling/wall.
d) 3 RFZ panels for RFZ
e) 1 HF Minitrap on ceiling above piano and 1 on the wall beside piano.

I am now left with 2 HF Minitraps and 2 Near Diffusors. I can put the
Diffusors on the back wall but 1. they wouldn't be in the centre
because i have double doors there and 2. may be very close to the bottom end
of the 6ft 5" grand piano.

If i put the 2 HF Minitraps on that back wall (and close to end of
piano) could/should i put the diffusors on the back 3rd of the side walls
(West and East). Then 1 of those diffusors would be very close to the
left side of the grand piano (would that matter much? put the diffusor up high? or on the ceiling?)

Rough sketchup of the room attached as a pdf

Any ideas? Thank you

Hello Ed,

I just responded to your email, but for posterity's sake I'll also reply here.

I think putting the HF MiniTraps on the back wall, and the diffusors at the back 1/3 of the side walls make the most sense given your situation. Having the additional bass trapping on the rear wall makes sense, there is usually a bass buildup there. And the diffusion won't hurt the piano sound at all.

The other possibility is to put the diffusors on stands, so that they can be centered on the rear wall. If you go this route, you'll want to put the HF MiniTraps on the rear wall, to the left and right of center (where the diffusors on stands go). Perhaps you could mount one of the HF MiniTraps to one of the doors?
