Center channel phase question.

Mike has a good idea with switching leads but you can do this test he suggests and have better results by simply using your calibration test tone so you have a steady easy to hear signal.

Thanks all. I think it's probably in-phase, but I'm going to roll the leads tonight just to check it out.

I haven't had any issues, but I do run my three front speakers full range and got to thinking about the phase of all speakers, especially since I use a different amp for the main channel.

"The front speakers should all be the same distance from the seating position. If the Center speaker is closer, the processor can delay the timing. Typically its 1 millisecond per foot. If you can set them equidistant with no adjustment, that is ideal. "

Another question just popped in my head. How many 1) actually follow this concept; 2) have ideal room setup/situation (unobstructed and equidistant); and 3) are willing, better yet know how, to adjust the processor to compensate for the setup shortcomings?

IMO, this is a major reason why so many audiophiles simply give up on processor based surround sound (gimmick is the word they use most often), bypass discrete MC, and concede back to 2-channel for everything (HT and music).

Basic principals like the one discussed here are essential for surround sound. Few are willing to learn why. Sad but true!

Cdwallace, I really don't think this has anything to do with my question. I was talking about checking the phase, not delays.

Delays are easy to set in most processors, especially one's like my Arcam where you just plug in the distance from the speakers to your listening position and the processor employs the correct dealys.

"Cdwallace, I really don't think this has anything to do with my question. I was talking about checking the phase, not delays."

Jack, is DSP (processor) based surround sound, when you have a speaker placed at a certain distance, and you tell the processor its placed at either further than or closer than the actual placement distance, it effects the phase of the drivers/speaker (in comparison to the other front speakers).

My comment may not have been directly related to your question, but it certainly is on topic and corresponds to the comment Steuspeed made.

Nevertheless, I'm glad your question was answered and issue resolved. I'll shut up now!
