door in corner of studio - bass traps?

[Kasey]

I'm finally getting around to fixing up my room acoustically, and the first thing I'm putting in are bass traps; two LENRD's in each corner. My problem is one of the corners (the back left corner if I'm sitting at the mixing desk) has a door, so I cant put bass traps there. What would be the most effective thing to do? just not put bass traps there but still have them on the other back corner? not put bass traps in either back corner to keep things symmetrical? put them there but cut a V out of the center so theyre there but the door can still open and close? I'm not sure what i should do. If i cut a V then i lose a bunch of bass absorption right?

thatd be great... but im getting LENRD's, those kind cost a lot more.

[notbradsohner]

make them



do a search for rigid fiberglass

[Kasey]

ok... i'll make them. I looked around and decided I'd get some 4" Roxul AFB insulation and get frames and fabric from these folk:

i cant figure out where to buy the roxul stuff in the US and how much it costs... can anyone help me out?

Get on the phone and call insulation suppliers. You'll be surprised at what you can find. Call this place: http://www.spi-co.com/servicecenterdirectory.mv

I'm fricken making my own bass traps. That realtraps site is GREAT and extremely informative, but man, those traps are expensive if you need 8 per room.

I do have a question though. 7 years ago when I was planning out my studio, I mis-unerstood the whole "bass trap in the corner" thing and I thought they were saying you should build your corners as 45 degrees to eliminate the collection of bass in the corners. So should I just hang bass traps on my 45 degree corners?

[pandamonk]

45 degree? bloody hell, lol.

[Kasey]

yes ive realized now how much smarter it is to build your own. I just didnt realize that you can make them so much cheaper and actually have them be even more effective than the LENRD's and stuff.

Yeah... I understand why you're laughing, and I don't blame you... but that didn't answer my question!

[pandamonk]

So the corners of your room are like the attached pic? Yeah I'd say hang them in the corners, I'm no expert though. BTW did you mean 90 degree corners or are your corners actually like that?

[SonicClang]

Nooooo not THAT way! The other way. Just the way bass traps hang in the corner at 45 degrees. The 4 black parts in the corners are the way my room is built, and will remain built because there's no way I'm tearing stuff up at this point in the built (6 years in).



Like this. I plan on putting bass traps on the 4 corners, plus wherever else realtraps recommends.

lol, except now you have 8 corners.

If you put some traps at the wall/ceiling corner in the middle of each wall span it should help. It would help to put some broadband absorption on those corners because they would seem to work as a reflector to channel everything towards the center of the room.

I would think you get some horrible flutter echoes in that room.

I actually don't have any problems that I can HEAR. I have to do the test they did in that video on realtraps.com to see how my room actually responds. I've got stuff in and around the room right now to help diffuse sound like a shelf with stuff on it, a couple speakers, a bass amp, some chairs. I don't get any flutter echo when I clap my hands anyway, so I know the highs are somewhat ok. I have no problem putting as many bass traps up as I need, and some broadband absorption.

I was kind of thinking when I designed the room that I'd be using it for 5.1 surround mixing... but in hindsight I didn't do nearly enough research first. But, this was 6 years ago, I can't kick myself now for it, I didn't know what I was doing.
