Speaker phase and timing

Thanks Gregadd and Onhwy61. I'll experiment with the system. The room is probably the limiting factor.

A strong early reflection or diffraction can ruin the soundstaging. The usual suspects are the sidewall first reflection zones and anything between (or between and behind) the speakers.

I use that Roger Waters disc to fine-tune speaker distance from the center of the listening position. I can measure and set up to within about 1/4 inch or maybe even 1/8 inch, but the final microskooch forward or backward is done by ear.

Get out your Stereophile Test CD, or a test record that has a phasing test track. I know that Sterophile Test CD number two has this, and maybe others. There is a track with a Fender bass guitar being played out of phase and then in phase. When everything is right that guitar snaps to center on the in phase track. I think this is an accurate means of determining if you are out of phase, or if room acoustics are somehow shifting your image. A couple of weeks ago, I discovered, by playing the test CD and the test record, that my cartridge was out of phase! Strange things happen, I guess. I can even imagine the factory messing up the internal wiring of a speaker, although it's hard to imagine Wilson doing it.

Speaker, listener, and furniture placement have more to do with imaging than your equipment.

Spousal friendly placements with the speakers or your chair just a foot or two off the wall behind them will not be good. A television between the speakers is not good.

You might describe your physical setup in more detail.

ditto the speaker placement measurement....if possible to within a 1/8 of inch,( toe angles ) ..... front wall to speaker- within a 1/2 if possible ....speaker placement as you know, is a BIGGY.. keep workin it, brent
