I just ordered up 6 ATS Acoustic Diffusers 23" x 48" x 6", QRD 7 type for the back area of my HT room.

I'll be replacing rear first reflection absorbers with two of these. I'll be putting 2 on the back wall while leaving bass absorbers. I'll be hanging 2 on the ceiling over rear surrounds over bass absorbers.

Look under "Clearance" they have them for nearly half price, http://www.atsacoustics.com/acoustic...clearance.html . They are unfinished but it's pretty easy to use
wood stain and varnish or a one step product.

I'd get more but I really don't have room for them till I do at least remodel the existing theater room

I've not ordered from ATS before so if you want to wait and see what my experience with them is I'll be happy to post back.

I'll post back when they arrive but they're not supposed to ship till 6/2 or 6/3.

Cheers,

Hi, guys!

I am doing my first home theater build and using sound treatments for the first time. I came across tube-shaped bass traps in the wholesale market dedicated to audio and home theater here in Guangzhou. Do these things actually work? They seem way too light to function as a bass trap. What am I missing?

Thanks!

They do work - probably. Some designs might actually be pretty good. Other designs are only useful over a very small bandwidth. Hard to say.

Good morning group,

Will get better pics, but this to start:

The pic is of my handicapped sons duplex. The echo is simply maddening. I placed an area rug, some vinyl blinds, some darkening drapes...The couch is pleather/vinyl, glass front picture hanging, vaulted ceiling(s) that opens into a very open kitchen, also with vaulted ceiling.

The plan: To make my own frame box, covered in sound deadening blackout drapery material. Question is how large, many and ideal placement?

The plan: 1 4x2 behind each tower and one 4x2 above the TV. 3 - 4x2 on the opposing wall above the couch...one near the front windows about 8" above couch back, the hanging picture moved to center over couch with 4x2 oblong above the picture (if space allows, this one may be sized to fit), and the 3rd panel above the end table.

Thoughts: Unseen as of yet, but thinking I will still need more treatments going into the DR/KIT open area.

Suggestions are most welcome as this I am just learning about, for the sole purpose of echo control on the cheap (but effective).

4x2 is a fine size and you're off to a pretty good start with the locations. If you are only using the stereo pair of speakers, with no center and normally not using the TV speakers, then the panel centered on the TV may be superfluous. The panel behind the listeners should come all the way down to be as close to the top of the couch as you can tolerate: directly behind your head.

You said, "sound deadening blackout drapery material." This is only part of the story. The panels need to be thick - like four inches thick - and filled with some kind of fibrous absorption - like rockwool; the classic recommendation for this sort of application is Owens Corning 703, but there are other similar products available. If you do that, the covering is a lot less important. In fact, the covering is best as a thin cheap fabric; again there are several options, but they should allow the sound to pass through them into the mineral wool interior.

If three panels in those locations is insufficient, I'd suggest even thicker panels in the corners, to help with bass response.
