Audyssey XT Room Calibration help....

kal, if you ain't a cable guy then fine, but...the receiver generates the test tone which in turn travels through the speaker cables which then is reproduced by the speakers. it would stand to reason that, if one beleives cables make a difference in the sound of a system, then a change in cable would change the readings audysee takes on the test tones cuz they will "sound" different. yes? audysee reads frequency response, speaker loudness level, speed of the response, etc. cables can and do change these things. would you recalibrate if you changes speakers? same thing. IF you're a cable guy. anything behind that chain can't make a lick of difference.

btw, those are very informative threads kal linked to. definately read them. calibrate as many positions as possible.

Well, Uncertainsmile, you do raise the two possibilities that I accept. Either one believes the cables make a difference or one does not believe they do. How would that affect one's need to recalibrate?

If you do not believe, then there's certainly no reason to recalibrate.

If you do believe that the cables made an improvement, then why would you want Audyssey to compensate and correct the change wrought by the cables you just paid for?

So, you can have it either way. ;-)

dude, it calibrates for optimal response in your room. IF your cables change the response of your speakers then it affects audysee's readings and calibration adjustments. what makes you think that audysee would cancel any improvements made by a change in speaker cable. in theory it should ENHANCE any such changes, otherwise why use it? with that said, now that i think of it the signal sent to your sub via your sub cable would change if you switch cables, recalibrate then too. c'mon now, be reasonable.

I am being reasonable in even entertaining that changes in cables make any significant difference at all!

Why would you assume that Audyssey would enhance a change in FR, for example, and not attempt to flatten the FR as it does with any system?

The most important changes that demand a recalibration are those that affect level, sensitivity, gain and, even then, only if they affect fewer than all the channels. Any change in level, for example, that applies to all channels needs no recalibration. By definition then, a change in the power cable for the prepro or AVR does not demand a recalibration.

Since Audyssey is actually MEASURING the sound objectively, you would first have to demonstrate that any of the cable changes make objectively measurable changes.
