You might consider DIY. There are lots of things you can experiment with cheaply, then buy the high priced spread when you know what you need.
For example, if you think you need sub traps (so many rooms do), buy a few round bales of ordinary fiberglass insulation at about $10 each (returnable to most stores), and try out the concept. Sure, this won't get you beyond 60-70% effectiveness, but that's a lot and will tell you a lot. Then buy the big stuff if you need it.
Look up the DIY designs. You don't have to build a tower to your power, you know. You can experiment cheaply with a variety of readily available absorbers and diffusers first. I built my room lens clones for about $25 for a pair and they worked very very very well! I could have mocked up a less effective facsimile more easily for less too.
I don't doubt that the commercial stuff is more effective. How far that goes, I don't really know.
Every room is different. There are a few popular and effective routes, not simply one, you know...
Follow Ups:
Thanks for the suggestion about the DIY absorbers. I was considering that in the past; however, thought the commercially bought ones were a lot more effective. I might be wrong in this. Also, when I priced fiberglass rolls, they were quite expensive, as I recall, and the materials alone probably would have cost nearly as much as the GIK stuff.
I might have looked at the wrong packages of fiberglass, though. Here's a question, if you leave the stuff in its plastic bag, does it work the same, or does the plastic keep it from working properlty?
He did all the spadework and is very informative.
Seems that the plastic does NOT affect low freqs in any significant way, but DOES affect mids and HF. So for quick and dirty check on bass trapping, I simply left mine in the bags and never looked back (nor felt the need to do more than this either).
Some of the commercial absorbers use Corning or other compressed fiberglass as their base or total mass. So if that's what they're doing and you buy them at not much more than constructing your own, then you might as well go commercial, especially if they have a generous return policy.
But you can check various methods with cheap DIYs, not simply fiberglass batting or panels, for most diffusion, diffraction and absorptive functions. You can also use that to see how much, how many, and where you might want various devices. Then go for the well made commercial stuff confident that you spent your money for real results you'll appreciate.
FWIW, the biggest component of any stereo system is your room. No kidding, you really need to deal with that or you'll never know how good your equipment can actually sound!
Thanks for the info. I'm thinkin' I've got a project (or two) awaiting me this weekend. I'll have to swing by Home Depot tomorrow after work to have a little looksie.
Thanks again.
