I couldn't believe a site like this exists!! Soo many interesting things to learn from...It's just awesome!!
I have a question about a design I've allready done some work on in practice. It's a 11x6 meters garage in which I've created a heavily isolated Live Room (lots of neighbours cause I'm in the Netherlands... )
Now I would like to procede with the control room but I'm a bit worried about the front end design. There's the only entrance from the live room into the control room. I'm thinking about moving the speakers more towards the listening position. This creates spaces behind the speakers.
Could they affect my room acoustics in a negative way. Can it be solved or should I think of another design?
Thanks for the input!!
I think it would be a good idea but my problem (or isn't it a problem) of having those spaces behind the speakers will stay the same.
I checked the link and I noticed the entrance is between the speakers. In my case it's behind them. My window is already finished in practice (red color in drawing) and that's in the middle. Hope I don't have to break it down again!
Since you've already committed to the window position, I'd suggest rotating the control room layout something like what I've illustrated below. . You'll still have a good view of the live room with just a turn of your head. Also, the sloped ceilings might actually be very favorable in creating a reflection free zone.
I'd undo that construction of that door placement and move it like we see in Thomas' modified floorplan for you.
It is worth it to unscrew/unmount a door and seal the enclosure than deal with the aggravation of people HAVING to walk through the live room to enter the control room.
In my own construction, I have undone some of the things I did because I realized a better way.
From the perspective of more optimal monitor locations, as well as a more optimal listening position (disregarding the spectators) relative to the monitors, I like my design a little better.
Below is a variation using angled rear sections to help break up the long parallel walls. Since the aspect ratio of that green rectangle defining the distance between the parallel walls to the width of the parallel walls is 3 to 1, the normal transverse room modes that would otherwise be excited will be significantly weakened and skewed (the transverse waves will "bulge out" in the center since the adjacent walls are too far away and too complexly shaped to support "pipe organ" resonances). Slot or panel resonators on the right wall could break up standing waves even further.
Hey guys...thanks for all the replies!
I'm kinda convinced (though it feels bad) of having to move my entrance.
Thomas, what do you mean by more optimal monitor locations?
Is it the distance between them? I also like your proposal bettter because John's proposal would imply another constructive modification (although not a major one of course ).
As you can see in my original picture I was planning some storage/equipment on my RH side. It is lost now! What if I narrow the whole space by 80 cm. to gain back some storage capacity? This would affect the ratio Thomas is mentioning, but I'm not sure how important it is to keep it.

I like to try and keep the monitors as far way from the adjoining wall intersections as possible - to avoid placing the monitors in the "horn" created by the two walls. I also like to keep the monitor center axis closer to the mixing position and not so far back. It's best to have your head no more than 5º off axis throughout the range of mixing positions.

Narrowing the room should be OK. I would then fill the top part of the storage space with acoustic hangers and make an opening in the wall near the ceiling apex. I've illustrated this in the picture below which is a view from the window wall looking towards the storage wall. The blue area represents a cloth covered opening in the wall and some of the hangers are depicted as well.
The green areas represent cloth-covered openings in outside front and angled rear walls as well. These cavities should also be filled with hangers. The openings close to the floor and ceiling do two things. 1. They leave the walls open and reflective - especially important for the walls near the monitors. 2. The wall/ceiling and wall/floor intersections help "funnel" the bass energy into the cavities.

Sorry...I must have missed part of Thomas' last post?!
I see some answers are in there. It will be possible to find an answer on those hangers in the acoustic section of this board, by performing a search.
I will check it out!
