Does anyone have a setup where they have placed their system in front of built-in cabinets which surround a fireplace?
How does this affect acoustics and what sort of treatment options/ideas do you recommend?
Additionally, I haven’t sorted out if I want to place gear inside the built-in cabinets or use a rack off to the side wall. For those who have placed their gear inside the built-in cabinets, what sort of special work did you do to ensure things were a) well-ventilated, b) cabling especially to speakers were able to be placed without keeping a cabinet door open?
Any pictures of your setup would also help with ideas! Thanks.

Are the cabinets deep enough for the gear?
Can you just remove the doors?
Do you have electrical power to the cabinets?
Can you route speaker cable behind/below the fireplace?
Acoustically randomly filled open cabinets would provide a bit of diffusion. High volume (sound pressure) levels could cause the cabinets/doors to vibrate. Closed cabinets/fireplace is less than ideal and precludes front wall treatment, but should be better than lots of glass or possibly even bare plaster/drywall.

JLM, hopefully some pics will answer your questions.
Here's the system as it is temporarily set up:

I am unsure whether acoustic treatments along the upper shelves would be worthwhile or placing random objects that allow for diffusion/absorption characteristics is sufficient. You can see a curtain on the left (thick felt) which helps tame the first point reflections off the left side (which are windows). The right side has built-in bookcases which are helping with first point reflections off the right.
The rear of the room opens up into my kitchen area so I don't have much issues dealing with rear wall reflections.

I would just set some QRD style diffusion in the rear wave of the speakers. I would also consider putting deep absorbers in the top shelf on each side for a bit of bass control.

VG advice listen to bpape.

Thanks.
bpape: Would the deep absorbers be placed on the upper leftmost and rightmost shelves? The shelves are adjustable and, hence I can occupy the entire cabinet space with absorbers or partially.
And I'm unsure what sizing for the QRD diffusors would be needed. Just speaker height and width?
