Odd length speaker cables


Given the considerable cost of most high end speaker cables and corner equipment placement in a non dedicated room I am in need of 18 foot run and a 5-6 foot run. How much detriment coiling 12 feet of cable on one side will have for signal path versus difference if one obtains 2 cables of different length?

Your dealer is wrong.
The better the equipment the more you will notice the
difference in the uneven cable length.

Well, that assertion should settle it for once and all. All
you have to do is be able to accept it.

I can't.
I don't believe 99.9% of people could tell the difference. Granted, its not optimal, (on paper) but, can YOU hear it? In a blind test, I would put my money on no every time.
I experimented with different lengths of cables due to an odd room setup. I obsessed over the issue myself. I could tell no difference with unequal lengths whatsoever. I don't mean any disrespect, but it seems a little far fetched to think anyone can hear difference in microseconds due to unequal lengths of cable.
Zydo. I agree with your statement:

''I don't believe 99.9% of people could tell the difference. Granted, its not optimal, (on paper) but, can YOU hear it? In a blind test, I would put my money on no every time.''

And Kr4's scientific contribution:

''How can you possibly relate these? Moving the speaker 1foot
changes the arrival time (at the ear) by a bit less than
1millisecond. Changing the cable length by 7inches changes
the arrival time by about 0.0006microseconds.''

Kr4, let me tell you how I relate. I use a very sophisticated instrument: My ears.
Sorry, Sonicbeauty, but you did relate these two variables in your statement and there is no scientific justification for it.

What works for me: I use a 16ft on one side, and 9ft on the other. This shifts the stereo image to the short side on the 9ft run.

I counter-balance this by advancing the 16ft side speaker about a foot in front, and the image centers beautifully.
Since you assert that you can fix the problem by moving the speaker a bit, you are extremely lucky or it is the result of something else.
