If it's at all possible, I'd switch the "home theatre" area with the "mixing" area. Where you have the mixing area now looks a lot narrower than the home theatre area.

Thanks, Rami. I wish that were possible. The entertainment center is huge.
I don't think I asked the question very well. I realize corner bass traps are needed, but I'm not sure if I would benefit from every corner having one in this room. Anyone?
I just had a thought for a DIY bass trap design; anyone ever used sheets of steel mesh as a frame for fiberglass or rock wool? I'd rather not get into the woodwork for this.
Like this, perhaps...

Ah, yeah that's what I thought. That theatre desk looks pretty wide.
You can never have enough bass traps, really. I think it would take lots and lots of bass traps in any room before one would come close to reaching the point of diminishing returns. Don't forget the floor/wall and ceiling/wall corners, too. Not saying you HAVE to cover them, but as long as there's an exposed corner, there's room for a bass trap.

I would bass trap the front corners heavily (with something like Superchunks/TriTraps or Soffit Traps). The home theater corners likely won't give too much of a noticed effect in the studio (but, you could always treat the home theater space too!!)
Considering you don't have much corner space by you, I would probably additionally trap the wall/ceiling corners around the mix position (along with the first reflection points).
Since you don't have too much space for tons of traps - make them all thick as possible so they're all able to absorb any resonances. Luckily, with the odd room shape, you shouldn't have as intense of problems in the bass as some small square rooms.

Thanks a lot guys. I'm looking for superchunk DIY ideas now. I also have to find a place to order some roxul, which seems to be a bit cheaper than the 703. No one in my area keeps that stuff in stock.

That stuff wouldn't be ideal at all. Not rigid enough. I use it quite often for tile underlayment.
If you don't wish to use wood, there is this build option. I made 10 of these. Actually quite sturdy, lightweight and portable. You can see that I hang two of them @ my website, in my control room when I record vocals.
Oh yeah, do not use the batting! It looks like crap and just adds to the expense. There is no need for it.

Where do you live? SPI is a great place to find Roxul 80 in the states.

Thanks, jimmsy69. Nashville, TN is the closest location and that's about 3 hrs away. My local Lowes and Home Depot can order it for me. You mention the Roxul 80 2" boards. Should I use the safe n sound 3" or Roxul 80 2" for the superchunk, triangle corner traps. It looks like the 2 inch will give the size triangle I see recommended. The boards for the safe n sound are a tiny bit smaller. I guess that small difference in size makes a big difference in sound.

Attached is my proposed layout. I'm thinking superchunks in corners 1-4 (possibly 5 and 6) and wall traps in the designated wall areas. Would this be a decent plan of action? Will the half-height corners benefit me much? Also, should the wall traps be 2 or 3 inch thick?
I'm also thinking about moving my mix desk away from the wall a foot or two; would that help?

I would skip 4, 5, and 6. If you can, get some absorption on the wall/ceiling corners around your direct position.
Why can you only go half height in the front right corner anyways? But yes, it will be much better than nothing.
As thick as possible really. And an extra air gap is helpful too. For reference, our slimmest bass trap is 5.5" thick. I don't really consider any traps thinner than 4" to give any significant bass trapping at all.
It might but it might not. Experiment with your desk/speaker placement a bit till you get the best response.
------------
Also, I would heavily suggest putting panels on your right side as well to get a more even stereo response. I'd immediately change that. I know there isn't a wall there, but I would build/buy/acquire some stands for them. Lots of reverberation on your right and dead on your left would be really awkward.

Hey nomad,
I dropped out of the conversation like I always do when Akexander or Ethan come in. Listen to this guy, he's one of the few true authorities on acoustics here.

Through my research, I found the Roxul 80 to be the best choice for me, regarding absorption performance and price. It is fairly rigid, to the point where no support is needed across the center of a frame. It absolutely needs some type of outer frame, in order to stretch cloth around it. It is squeezable.
In my drum room ceiling, the only thing holding it (4" thick Roxul 80) in the ceiling joists above, is the material itself (cut 1/4" wider than the space) and cloth stapled to ceiling. Oh yeah, you can get it in 4" thick 4X8' sheets for the same price as 2-2" ones. A bit more solid that way.
My last batch of traps were made with 1/2" pine frames. All you really need to make these is a hand saw, wood glue, stapler, and drill/bits and screws. Was much easier with radial arm saw, and pneumatic nailer tho.

I'm no expert by any means. I learned from these guys, and what worked best for me with their gratuitous advice.

That's what I was hoping. It gets to be expensive.
Half height is where the angled ceilings meet the corner. It's really about a 5ft corner on corners 2 and 3.
Will do. Thanks.
I agree. I always thought my ears were playing tricks on me.
Thanks much for your help.

Thanks, jimmys69. I found Roxul safe n sound 3" panels(roughly 2'x4'x3") at a store for about $20 cheaper than 6 panels of the 2" RXL80. Is the safe n sound okay to use?
I'll have to get creative with my frames. A lot of weird angles and spaces to fill. I'm not really sure to do about the window that butts up to the corner right in front of my mix desk (Corner 1 in my diagram).

Yes, Safe 'n' Sound will work. If you can on at least some of the panels, doubling them up to be 7" thick instead of 3.5" would be better for bass absorption. Safe n Sound is a bit light so, for thinner traps, the Roxul 80 would be a better choice, but for thicker panels, Safe n Sound would be best. (They will both work in either thickness though, just a matter of efficiency)
