Agree with both comments above. Re: cellular shades - this is a very cost effective room treatment. Hunter-Douglas 1" cellular shades lined with aluminum work wonders at ridding the room of the dreaded "glass reflection factor". Could be very helpful depending on how much energy your loudspeakers throw to the rear (rear firing tweeters for example).
Thanks for the input so far. The window behind the speakers has vinyl vertical blinds that run top to bottom. I'm assuming those will work pretty much like the cellular shades. The speakers are sealed enclosures so there are no rear-firing tweeters, etc.
As far as additional room treatments I'd love to be able to spend $1k on them but right now that's not going to happen. We sit on a couch that is up against the wall opposite from the speakers. The good thing is the couch is slightly overstuffed and is long so it does cover alot of the wall length. Are there any wall mountable DIY treatments that others have had success with?
Also, given what you know about the room and our equipment/listening preferences are there any speakers (<$750) that might be worthwhile looking at as replacements for the Altecs. We could go with smaller tower as well as bookshelves on stands. The maximum we can really move these into the room would be about two feet off of the wall.
Vinyl blinds will function nothing like cellular shades. The cells (or even better, double cells) provide the functionality and not the surface (even if it was the surface, you are comparing relatively hard vinyl to cloth).
Some other things you can do inexpensively (after you spend some on the cellulars):
-deal with first reflection points
-bass traps (I like the Realtraps Mondo's)
Goodluck & Happy Listening
You should at least look at these:
You can use the link he provides for the Tyler site to look them up.
His link to other pictures (which are a little better, not much) does not work. This should:
The pictures are lousy, but it looks like these might be the cherry cabinets which are very high in WAF.
His price is good of they are in good shape. These are good with 60 good watts. They are also fine with 200 (but not at full gain).
Others to look at would be Totem Model 1 or Totem Arros.
All of these offer pretty good resolution, but a slightly warmer sound. I would think that would be good for your room. All are good looking speakers. Search here and audio asylum for comments on these and you will learn plenty about these and otheres.
