OTHER than the price, what is the general concensus on their products?

No idea ;D
The realtraps are very effective but way too expensive for the average HT budget. You can build the same thing for 1/10th the cost if you have time and do a little reading.

They're effective, but since you're a DIY guy you might want to checkout another page of the subwoofer guide I'm writing. home.comcast.net/~thomasw_2/SubwooferSetupandEQpage9.htmlIf you click on the modify for your first post you can see that somehow you chose the "laugh" in the message icon box when you made the post

I browsed through Thomas's work in progress as well as quite a few of the links, and it's a promising page. I've always believed that treatment combined with proper measurement can be powerful tools. I thought I'd pass a couple of treatment links: Obviously you know Ethan Winer's RealTraps... which he started following public interest in his bass trap articles. These articles are still available on his web site at www.ethanwiner.com/basstrap.html ... as well as several other acoustic related topics. He is active on several forums and you could DIY some of his if you want. BTW, the Fiberglass 703 could be replaced by a roxul of similar density... There is Auralex at www.auralex.com, which is a readily available and lab tested brand of acoustic treatments. They offer free consultations by email and actually have the www.acoustics101.com web site for general treatment information as well. There is Foam by Mail who is basically an inexpensive alternative the Auralex. They are a foam manufacturer and sell both directly and on eBay (as the "Foam Factory Inc.". www.foambymail.com/soundproofing.html Ironically their eBay prices are lower than the web prices... ROb

My current page is just an introduction to the various kinds of traps. Later I'll show how to measure (map) the room, then design and install some traps with tests to show how effective they are. Auralex has a nice Whitepaper www.auralex.com/literature/acoustics101v3_0.pdf

Thomas, will your "trap" page cover just bass traps or all types. I need help with the high end of the spectrum as well as the low. 2 channel in my living room is abysmal. I believe that it is due to the wall that I have the speakers on. It's a rectangular room with a peaked ceiling. The mains (and IB) are on one of the walls with the peak, which I've read is the worst wall as far as imaging goes. I can take my mains and put them in another room and they sound as if they've been upgraded. Multichannel HT listening from the "sweet spot" sounds more like I'm listening to one speaker than 7. I attribute this rightly or wrongly to too much sound bouncing around. I know less about room treatments than I did about sub building. Of course this forum made that particular project successful. Thanks for the help on this and in the past. Carl

Carl,
Although it says 'bass traps' it really deals with all kinds of acoustic treatments. The only real difference between bass traps and those for higher frequencies is that bass traps are thicker, when made exclusively from acoustic foam or fiberglass.
Specialized tuned bass traps have a combination of a resonating panel/membrane (usually thin plywood) suspended in front of a layer of fiberglass (that's the design of Ethan's RealTraps)
The trick with any trap is getting SAF/WAF for their placement, since they don't exactly add aesthetic interest to the decor.
Also understand that trying to trap anything lower than about 80Hz is very problematic unless the traps are VERY deep.
For example......
In the front corners of my HT, there are floor to ceiling 1/4 cylinder fiberglass traps that have 24" radius. Those kill very low frequencies.
My HT had treatment put in some 15yrs ago. The family room with the small IB has no treatments. So mapping and creating treatments for it will be the example for next section of the paper. Since it's a more public space (open to several rooms), the treatments will need to be more SAF/WAF friendly than those in the theater

If anyone in the Detroit area is interested, I ordered to much Roxul and have 3 cases of 4" and 1 case of 2" unopened extra. I would cut you a real good deal on it. SAM ZEOLI. PIKEMAN71760$hotmail.com
