Studio door entrance between soffit mounted speakers?

Hi all, I am looking to soffit mount my Adam A7s, but have one concern that the entrance to the studio will be directly in the middle of the speakers... Im planning on mounting a 4" broadband panel (Knauf Rockwool RS45) onto the door (spaced a couple of inches from the door.) However, could having the door in the middle of the room pose any problems acoustically? Here's a plan diagram of my current setup: And here's a plan diagram of the proposed new setup: and here's a picture of the mixing position: the room is 21 feet long, 12 feet wide and 8 feet high at the front half of room and 9 1/2 feet high at back half of room. note - heights are of two false ceilings, the actual height of the roof is 11 feet sloping to an apex at 14 feet I plan to use the studio to record music myself and occasional bands too. I plan to keep the studio as one room to give me a good room length as a control room, but also to allow me to record instruments myself without having to keep going back and forth from a recording room to a mixing room I mainly record Indie/Rock/Pop music, but also record a lot of synth too (but not Drum 'N' Bass.) Any ideas? Thanks, Aaron.

Hi Aaron, and welcome! :) Sorry about the lack of response on your thread! It seems I'm the only guy around helping out right now, and my plate is kinda full! Anyway!

It shouldn't be a problem, if you do it right. One of John's classic designs here is a studio inside a shipping container, where the door is in the middle, between the speakers. From what I can see of your "proposed new setup" drawing, you don't seem to have problems with reflections off that door, but you should ray-trace that to make sure.

That's not a very good ratio! It fails one of the BBC critical tests, and the modal spread is very uneven: The Bonello graph looks like a picture of the Alps! You might want to consider playing around with those dimensions to find a better ratio.

note - heights are of two false ceilings, the actual height of the roof is 11 feet sloping to an apex at 14 feet

When you say "false ceilings", what do you mean by that? Are you just taking about typical drop ceilings with so-called "acoustic" tiles? Or are you talking about a proper new angled ceiling that you plan to build, properly decoupled and isolated, and tilted to the correct angle? Also, you didn't mention isolation: I'm assuming that the dimensions you gave refer to the surfaces of the inner-leaf, not the outer leaf that we see in the photos? - Stuart -

Hi Stuart,

Hi Aaron, and welcome! Sorry about the lack of response on your thread! It seems I'm the only guy around helping out right now, and my plate is kinda full!

thanks for the reply, I was starting to feel unloved.. :lol:

that's good news, I was hoping you'd say that! :D regrading the room ratio, what dimension/s would I need to change to improve it & how would I go about doing this? (I really have no idea :? ) The false ceilings are made of 1 layer of 15mm plasterboard with 4" Knauf RS45 Rockwool (45kg/m3) packed between the joists beneath the plasterboard. (the joists are suspended via joist hangers from the front wall that extend to a large beam that is held up by two large brick pillars, just over 8ft back.) I would assume that this means the ceiling is not isolated or decoupled? I have built 2 hard-backed clouds (filled with 8" of RS45) both are 4ft x 6ft, I plan on mounting them above the speakers and listening position, would this resolve this issue? thanks, Aaron
