acoustic foam placement.

[Zane1Tsu]

Unfortunately, due to limited space, I cannot center my monitors on the wall of the room for mixing. They sit about two feet left of center. Unfortunately, due to my significant other, I can't seal acoustic foam to the entire wall. This leads me to a couple of questions.

1: With limited amounts of foam (Aurelex: 2'x4' plus severel more 1'x1' pieces ) should I center the foam behind the wall, or behind the monitors?

2: What is a good way to mount the foam without bonding it to the wall. (She doesn't want me potentially destroying the walls. And if I move, I can remove the foam without tearing it and save it for the next house.) I was thinking of bonding it to cardboard, then nailing it up.

I did a search and didn't see much on this, probably because it's a dumb question, but I'm not much of a handy man....thanx

Use T-Pins to mount the foam - look at a shop in with the curtains.

I'd do the foam centered between the monitors. And, make sure that you offset the side reflection point panels to account for the difference in centering.

thanx, I'll look into the T-pins.
What do you mean with offsetting the side reflection ...?

[chugheshc]

he means, make sure that any panels you put on the walls that are intended to trap the side reflections (sound reflected from walls that are perpendicular to the speakers) take into account that the speakers are not centered -
the speakers that are further from the side wall will need their panels moved forward to where the sound from the speakers would be hitting them.

Good to know, thanks.

I've heard talk of velcro, but not much. Not sure if that's better than t-pins, but I have the same prob, so I'm glad this thread is up.

i got some interesting magnet/mounts - used to attach ceramic tile when
you might want to move it later. I think it would hold up a sheet
of 703, but it would be toough to attach. I used it to attach a frame w/cloth to voer some 703 in a wall acvity.

to mount i used some spray adhesive(elmers).... use a medium amount it it wont harm the walls.. i have used too little and sometimes they will fall off with temp changes..

i just did a quick test for ya and was able to remove one with no harm to the wall

as for placement... it is best to cancel all first reflections.. (ie all reflections that only bounce once between the speakers and your ears)
my technique was to sit in my normal monitoring position, then have someone else (hopefully your significant other would help ya, mine did) move a lil mirror around flat on the walls... every where that you can see your monitors in the mirror is a 'first reflection' point .. attach some foam in those places (dont forget the ceiling) . and you should be good to go..

my room only required a minimum of 7 pieces of foam..

Unfortunately, when it comes to this type of stuff, significant others are usually MORONS. Do what your gonna do and tell her to fuck off. THEN fix it when you move...otherwise, your a pussywhipped idiot who'll get nowhere with this stuff.

Love it!

The only reason I suggested the T Pins is that they'll do the least damage to the wall. Velcro, magnets, etc. require some kind of bonding to the drywall surface that will usually cause minor to major damage when removed.

T Pin holes can easily be removed for changing placement too and only leave a very small hole - no worse than hanging a picture.

- or ditch the wife as Rick suggested...

T-pins are the way to go. I used them and it makes the job go faster and it allows for changes in placement.
Make sure you put something over your thumb because it will start to hurt after a about 10 pins or so.

I tried the T-Pins, works great, you guys are awesome. As far as the significant other, the house is in her name. The house I own is shared with my brother and is significantly smaller. So, her house is actually the best option. But if I ever really needed to move things, I could, being that the foam is easily removed. Thanks, again!
