Severe Imaging Problem

David, it sounds like you've tried this already but it sounds to me like a phase problem. I have an inverting preamp so I swap the leads at the speakers. I have experimented both ways with the speaker cables and on some recordings it makes a huge difference, images way outside and in front of the speaks, and on others it makes no difference. Be careful with the source material you are using, some recordings are not in absolute phase. The phase is often changed many times during recording, mixing, pressing, etc. That's one reason some recordings sound unbelievable in regard to imaging and some sound like crap. That's when most audiophiles like myself get out of the chair and start moving speakers around. Big mistake. Make sure your speakers are connected to your amp in correct phase with each other. Lastly, side wall reflections aren't causing the severe problems you've mentioned although they are the most important to dampen in my opinion. Your image may pull to one side or the other but not like you've mentioned. Hey, you are no doubt in audio hell but rest assured there is a way out. Good luck.

hi david, if i understand ewe correctly, reversing the interconnects leaves the same imaging problema at the left speaker, & the right speaker is still ok, even tho the channels have been reversed? i guess it *is* possible that the asymmetric location of your window alcove could be doing this, but w/proper room treatment, i'd be surprized that it's such a noticeable problem. are your speakers mirror-imaged, or can you switch 'em? assuming ewe are *sure* you've addressed *all* the proper-phase issues, and wall-treatment issues (try a sound-panel in front of the left-side opening of the alcove to mimic the right-side wall?), i'd try switching the speakers themselves... good luck, doug

One thing that the xlo disk helps with is checking every possility of phase probs, along with the solutions. If that doesn't seem to be the difficulty concerning l and r imaging, then you might want to consider hiring an acoustician. The guy will come in there with all the expensive equipment and properly install treatments. I just think for a really complex room situation, that that is a reasonable solution.

Sedond,I tried putting a sheet of plywood over the alcove.No difference.I have made some small speaker adjustments and presto! Lateral imaging to the left.Its not as good as the right side but I think thats a treatment issue that I will get to next.Thanks for all the help!

Correction to above.I made some major speaker adjustments not small.A foot farther from the side walls.4 inches closer and toed in 1/2 inch or so more.
