My new control room

Hi,

I discovered this place a few days ago, and I was working on the drawing of my future control room. Please tell me what's wrong and what to do to improve it.
The room is 3,60m high, all the dimensions are in cm. The speakers are 15 inches coax drivers in vented enclosure.

Thanks.

Hi JM, its myself cause nobody wants to answer you

.

Your design is

so I give you another one. There is a window on the left hand and a door at the bottom.

Regards

JM

Hi JM,

Great work, but where do I put absorbent materiels and spread materiels ?

Excuse me for my two $ english.

Jan, first let me welcome you to the board - second, your english beats the crap out of my (non-existent) french, no apologies necessary.

Third, do you intend to use the room for surround mixing? If so, you may want to re-scale a bit so all speakers can be equi-distant from your head.

I missed your first post til the next one was up (not my main forum, sorry) but the lack of a posted drawing the first time could have been part of the lack of response.

Your intentions regarding surround mixing will change the recommendations for treatment of various walls, so we would need an anwer to that before beginning discussion of treatments.

Also, am I correct in thinking that your dimensions are in centimeters?

Waiting for your reply... Steve

Thanks for answering Steve.

The lack of posted drawings is due to the fact that I was on the wrong way. I started with the monitors close to the longer wall.
All the dimensions are in centimeters (I have not to much ease with inches !)
This control room is made for stereo mixing and probably a little bit mastering, but I keep in mind that the future is surely multichannel. I have seen that the rear monitors would have to be closer, but a little, and I thought that I could have tuned that with a digital delay. But I can try to find a solution for that.
I do not want to make an LEDE design, I think it's not the way to go for multichannel monitoring.

And your french is not non-existent as US people use some french words as voila, rendez-vous, cul-de-sac... That's a good begining, isn't it ?

Here is the last evolution of my drawing. Any comment is welcome

"And your french is not non-existent " - certainment; jem appelle "ze knightfly", and Monsieur has caught me in a lie (albeit not a big one, since I am nearly done , other than "garage", "e claire", and possibly "fait accompli" - so I'm only 99.997% illiterate in the language of love...

One thing I would consider changing is the two little "jogs" in the front walls near the speaker flush mounts - having little pockets like that can cause either "acoustic lens" effects of concentrating unwanted reflections, or strange diffractions, or both. It would be better to continue the side walls to the speaker baffle extensions, even though this may cause a bit of "horn effect", where the speakers are effectively putting out a slightly narrower sound field. I've marked the areas in lavender on your drawing.

Are you clear on what types of treatment you plan, and have you checked out comments on the subject very much? What specifically are you unsure of?

Layout generally looks good so far... Steve

Ok for the jogs, I wondered what was the best so close to the stoffit mounted monitors, that jogs or not, you answered, thx.
I updated my drawings
Same situation with the window, I think I will put the second window (in black) in the continuation of the baffles, and it will make this second windows non-parallele to the other.
Am I clear with the types of treatment ? What a good question Steve !

I have some ideas, but still not totally clear. I thought to have absorbant areas in the blue (and lavender too !) sections. I'll probably use rockwool panels at 90° from the wall and cloth false wall. In the orange areas, I'll use fiberboards instead of cloth.
I wondered if the Sabine law was a way to go for this size of room ? And is it a good idea to use resonator panels to lower the room modes (as the frequencies of those panels aren't very predictable, no ?

Thanks a lot.
