Geez, remind me not to help *you* move. Didn't their families come looking for them after a couple of days ?

I just read an interesting article on room acoustics and thought I would share the link. It aims to provide a basic understading of the various priciples involved while covering some examples of problematic rooms/objects, and tips on materials and placement

The author mentions the use of plants and actually includes a table of absorption coefficients for several species.

Link.

>>> Good questions Rick, for me I don't think the HSF stuff would look that bad. My back screen wall is painted flat black and my side walls ceiling are painted a dark navy blue. Since this room is a dedicated HT room, like a theater, it might work for me.

Actually I believe the HSF panels would go with your room very nice Randy, and they do seem to be priced right ... they'll look really nice around the pool table, uh huh!

From one SRV fan to another, check these sites.. Ethan Winters has quite a bit to read, but for those looking for the magic behind the curtain, you will find quite a bit of it there..
http://www.musicplayer.com/ubb/ultimatebb.php?/ubb/forum/f/26.html
And another:
http://forum.studiotips.com/index.php
And, for those that want to come all the way over the dark side, http://ibsubwoofers.proboards51.com/index.cgi
...
And yes, you can dial in the amount of acoustic treatment you want.. Home theaters tend to be more on the dead side, as opposed to studios and music only rooms, which favor the livelier brighter room..
Oh, the older style wiremesh/box/compressed fluff has been pretty much replaced by the factory compress 700 series style, mineral wool, and acoustic cotton..
Lots of good reading, hope it helps..

Looks like GIK is offering a 10% discount over on AVSforum on their new corner Tri-Traps. When ordering on their website from now until 7-20-2006, use coupon code "AVS" and you'll get the 10%. So far I have not found another Bass Trap with these impressive stats, or approved by Riverbank Acoustical Laboratories (RAL). This is very tempting.

The ONLY TRI CORNER Trap on the market! Until now, acoustic enthusiasts had to make do with foam wedges for corners which are unattractive and far less efficient in sound wave absorption than acoustic panels. BUT NO MORE! Our dedicated sound engineers are proud to introduce the GIK TRI-TRAP. The Tri-Trap, like all of the GIK bass traps, was lab tested at the prestigious Riverbank Acoustics Laboratory and the results were amazing. The Tri-Trap has true effects at 50 Hz and below. The Tri-Trap has been effectively designed to absorb more low end, but also does an excellent job of absorbing the high end, creating smooth sound absorption from 50 Hz to 5000 Hz. Installing our Tri-Traps will result in a beautifully balanced room that will suit even the most critical listener.

Randy I went ahead and ordered a pair of the Tri-Traps and did get the 10% discount using the 'AVS' coupon code ... after reading a couple of reviews (including Audioholics) I concluded it's worth a try, so whenever they arrive I'll share my thoughts.

Those look pretty sharp... like Ethan's "Soffit Traps" but designed more for wall corners than ceiling corners. You realize everyone is going to want "before and after" response graphs from you, right ?

I'd love to graph the room John, I'm just not sure how to go about doing this ... keeping in mind that PCs are far from my expertise.

Audibly, in the sweet spot there seems to be just a very minute loss of bass as opposed to the rest of the room, even just standing in the sweet spot I can hear a very slight difference. In my 25' x 14' room I have the couch 9' from the back wall, which going by the 38% rule is where it should be positioned for the flattest response ... I'm thinking the ceiling may be causing the oh so slight bass loss and am hoping the traps may tighten and tame the bass just enough to change that slightest difference. I've tried moving the couch forward and backwards and this position seems to produce the best overall sound.

Luckily I believe I have a very good acoustic room overall but I'd like to maybe tighten the bass up just a very small amount and I believe the traps may help. And also believe me whenever I tell you that I typically don't fall for the snake oil stuff but have read enough to believe it's worth a try.

Now, how do I graph the room again?
