Room treatment

[1tribeca]

Question...

I'm wondering how affective simple foam type panels will be along the walls of my den/home theatre? The room is approx. 16 x 9, rectangular...a bass trap nightmare! I have limited space for treatment (plus, to be honest, I don't want the whole room covered in foam like a rec'd studio...it is my house after all!) I've been in contact with a couple manufacturers about treatment options (one from this site actually) and they're fairly helpful. The problem is, I think they probably oversell you on panels & solutions.

Will one gain (or lose actually) any significant audio properties from hanging a number of panels on all the walls? Assuming the proper foam is used, and each panel is approx 2 X 4?

What are my options?

If you are thinking egg crate, or similar type foam; I imagine a few well placed panels could do some good for higher frequencies, but all the foam panels I know of that are around one or two inches thick will be ineffective for bass.
So if a large amount of wall area is covered in it, you'll end up with a room that's nearly anechoic for highs, but has bad sounding bass.

If you could add treatments to the corners of the room in addition to the foam on the walls, you could end up with a nice sounding room. Maybe add some diffusers too.

I am attempting to build mine now. I found the fabric and picked up the mineral board yesterday. I am using the Ready Acoustic frames for the 4'' panels behind the speakers and I will use some nice Tapestries on the side walls which will cover 2'' panels. I will let you guys know how it turns out.

Greg, make sure the tapestries are very loosely woven and are actually attached to the panels (using some spray adhesive will work perfectly). This will allow for maximum absorption at all frequencies. If you don't have a loose enough woven fabric (wool ideally) there will be no high frequency absorption also, if you don't have the two coupled together it could inhibit some of the lower end absorption.

I hope the material I got for the panels is ok. You can let me know on Saturday.

Can one manufacture their own bass traps? with any effectiveness?

I have a 14X24 finsished basement room with 7.5 ft lowered ceilings. I feel that the sound is too dead. The highs are nice as they never get really harsh. But the bass is never really enough to fill the room. I notice when I get to the stairwell it the bass gets louder but not enough in the listening positions. What can I do??
