How to get an even stereo image

Post by laurentius »

Hello everybody,

we have arrived at a stage where we have to take definite decisions about what to buy and how much for room treatment. So I'd love to get a 2nd (3rd, 4th ?) opinion from the seasoned pros around here.

The room in question is intended for mixing and composition work only, no live recording or other frivolities.
Sound proofing is not an issue as there are no neighbors around that we could disturb.

The problem with this room is that it's completely asymmetrical, which makes it a hard task to get a somewhat even and well balanced stereo image.

I attached a picture of said room - I'd love to know what people around here think about this! (All measures are metric)

Adding to our room's asymmetry is a large venting shaft to the left of the ceiling (see pic),
ending pretty much to the left of our desired listening spot...

Do you think this could be a major problem or is this something that can be fixed with good absorbtion as well?

Thanks in advance
Lars

welcome! please update your profile to include your location information. is this diagram showing the plan view or section view? if this is the plan view (meaning your wall is angled and not your ceiling) then you could build out the front wall (left) on an corresponding angle to force your listening position and boundaries to fit symmetrically. on the soffit, some absorption around it in proportion to the other absorption in the room should do it.

Hey Glenn,

thank You very much about this proposal. We have also thought this way, but then we unfortunately have too limited space positioning at least
2 pairs of speakers.

What Do You think, is there any chance to use the other side as the front wall?


Aaah yes, it is a floor plan :-)

i think turning it 90° to the right and making the side wall a flat angle to make an angled side wall and making the back more absorptive will be better since going the other way you end up with a compressing space. worst case - tr to make some acoustic measurements with the mix position facing the big wall.

Gulfo,

thank You very much for Your thoughts about this and sorry for the delayed answer. Was out of town for a while....
Will definitely do some measurements, of course.
But anyways, just for better understanding:

if I choose the "compression space", wouldn´t it just be important to work with more absorption than diffusion panels?
I know that DELE- might not work...

you can always try it and see if it works. if it doesn't then you might have to sort out some options for walking around the speakers and desk.

Will do. Keep You posted.
At the end of may, the rest of the furniture will arrive, and THEN will measure and treat it correctly.

So far, we have 6 pretty large and well built absorbers filled with basotect.(7cm)
We are in the making of 6 more filled with rockwool (10cm).

We know, that we might never get a "linear" room, but making this room sound nice is pretty tricky.
