Making the best of mediocre speakers

This may be a dead issue, but I would revisit the question of whether you might find a way to use conventional speakers in the room. I have a pair of Salk SongTower QWT finished in Hawiian Koa wood. My wife, who has rarely seen a speaker that she likes in a room, okayed these. She treats them like pedestals and displays something on top. I have my SongTowers at one end of a long series of open rooms and they project throughout the open space quite well.

The SongTowers received very good reviews, have a small footprint, can be custom finished to blend into any decor, are flexible in placement and have great dispersion. These sound good to my ears even when placed in less than ideal locations. You might try a SongTower or variant thereof along each wall.

My suggestion would be to contact Jim Salk at salksound.com. He might have some additional suggestions for your difficult room. Since he custom builds speakers, he may also be able to offer a speaker you could mount on the wall or place in an acceptable location as an alternative.

There is a forum on audiocircle.com for Salk where you might post and get additional suggestions.

My frst choice would be a nice pair of full range speakers , Maybe something nice looking like vienna Acoustics etc.

If that is not possible There are many inwalls that are excellent. For example Speakercraft makes expensive in walls that you can get which also have two enclosure options, foam and metal. The enclosures make a huge difference.

Lastly my advise for the best system is to get the best source. A better CD player or Dac if your doing a music server will make a bigger difference that the electronics once they are past a certain point.

A true listening room is very hard to find, indeed.
But, if you are considering in-walls, I highly recommend RBH in-walls. I use them for home theater and friends use them for 2 channel. Very impressive. The bigger 8" woofer has ample bass, but a sub helps.
You can find good buys on eBay.
Good luck and let us know how it works out.

there are models from Thiel, Dynaudio, Krell, Etc

Thanks everyone! The wisdom of the forum makes me think I'd better opt for on-walls as opposed to in-walls, search out a speaker with angled tweeters, get a decent sub, and spend on good sources. No JRDG for me!
