Skewing the parraelle walls verticly?

In I 42' x 15' room I will maybe try to make a control room of 15'x21-22'.

The problem I face is the 21' walls will be paraelle to one and other. I was thinking the best soloution that would use up the least amount of space would be to skew the paraelle walls verticly. The room is just 2 by 4's right now (aside from the roof) so I could just cut some 2x4's diagnally and nail them on top of the existing ones. Then Sheet rock on the angles.

Does this seem like the best solution acusticly? I should mention that the ceilling will pitch up into a peak on center between these angled walls.

If I was to do this, would you suggest to have the walls angle in or out from the floor? The paraelle walls are 5 1/2' high. I could also double angle them like making a long "V" shape (in or out).

Anyways, which would bring the best results? Or do you think I should just try to skew the walls horizontally and consume more space?

Thanks.

Mongoo,
walls (especially front side ones) in CRs are usually splayed horizontally so that they direct the reflections to the back of the room. Vertically angled walls probably couldn't do this

Your thinking,though, is good.It would save the floor space, but this is rather hard to do in CRs.Live rooms-No problem.

Yes John. I mean something like that but with just sheet rock that lays on diagnoly cut 2x4's that are attached to the walls 2x4's.

I can see that this might not improve pusing back the sound to the back of the room, but Wouldn't it improve the standing wav's bouncing back between the two parraelle walls?

If I was to do this would I want to do it to both walls or would one verticly angled wall do the trick? What do you think of instead of angling the 5 & 1/2' walls like a "\" I could make it a sideways (really streatched out) "V"?

Like I say, I see 4 possible options with verticly slanted walls. The "/", the "\", the Sideways "V" with the point pointing into the room, and the sideways "V" with the point pointing into the walls.

The "V" shape would save the most space I think because it would only extend half the distance into the room that a "/" or "\" shape would.

So overall, Are you saying that veticly angled walls can be used in replace of horizontaly angled walls with equall success in "Live" rooms? If, so this would be a great way for me to save space in my small live room I'm designing. Its averaging out as 12' x 12' useable floor space with horizontal walls. I could probably make that 14' x 12' or 13 with verticaly angled walls.

Quick question about the control room. With (ruffly averaging) a 15W x 22L x 9 1/2'H control room. If I was to add horizontal angled walls along the 22L demention, what angle would I need to get results with still preserving as much space as possible. For those who know there math, how many feet would I lose at the loosing side of the room in this equation?

Thanks

Your control room is really nice size.As I'm not as qualified as others here (John etc) to give advice, take it with a grain of salt, but I think you'd be better off splaying them walls horizontally.If I'm not mistaken the minimum angles that the walls should be splayed at, to get rid of flutter, is 6 degrees EACH.12 IN TOTAL. I think for 6 degree angle it was like loosing a foot of space for a ten foot angled wall..??

I don't see a problem in vertical splaying in live rooms.I think the posted picture might in fact be of a Live room..John??

I think you save the most space by angling the walls in rather that out, such that the floor is wider than the ceiling. Furniture, gear, and people stand on the floor, so you want more space down low.

hypotheticly speaking if I don't want to horizontally splay the side walls, what other options are there to get good sound in that room? Whats the next bset thing?

Just so, I'm clard about this, I'm not talking about the front side walls of the control room, but more the back side walls. I've already included some horizontally splayed walls in the front.
