Speaker imaging

check out Jim Smith Get Better Sound. i bought the book a few years ago and think it is full of useful setup tips. this would not be a quick fix but might be worth it. i think by now he has several different books and even a setup DVD. good luck tweaking

I'm only 10" from the speakers. So os fairly near field.

Pulling the speakers away from the wall eliminates all bass below 90hz. They are rear loaded horns and use the wall as part of the horn expansion. So pulling them away from the wall isn't really an option either.

I also use horns and have pulled the speakers 5 feet from the wall and used a sub. But, if I may give you a new direction..........are your cables broken in?  You may laugh because you have put in a few hundred hours on them, but with single drivers, I have found that it does take a lot of breaking of all cables to get the sound stage right...... just my experience.

shreekant :)
 
I think the following may apply to this topic of room treatment. It is as much a question as anything. I have been thinking about how different materials for absorption handle different frequencies, and I have wondered in cases where a room needs a lot of absorption on one side, whether or not 'memory foam' would be more useful than other materials.  Your thoughts everybody.
 
A standard sound-absorbent material has the optimum flow resistance - that is, it is harder than air and softer than wood.  :^)  You can blow through it with moderate effort, more like a pillow than a fiberfill comforter. It will absorb sound pretty well when the material is more than a quarter-wave thick. A wavelength at 1kHz is about a foot (34cm actually) so a 3" pad is good down to 1kHz. The memory foam I've seen is very hard or impossible to blow air through, so it would not be a good absorber.

That's from the simplest theory. Clever material designers can push this lower, maybe as much as an octave, by exploiting more subtle material parameters and/or non-uniform materials. And a thinner pad of higher resistance will absorb less energy but do it down to a lower frequency.

I have left out bass traps which get to much lower frequencies but only in a more narrow frequency range, by exploiting resonances.
 
Thank you Paul, Everything has a song when it comes to resonance.  I have long been interested in acoustics, as things are not as you might expect. This leads me to constant curiosity.
