Speaker cable length for L/R channels critical?


I have a good system that utilizes some older discontinued speaker cable that I like a lot. It is 10 feet in length and I need that length to reach the left speaker. The amp is not (and cannot be) located center between the speakers.
The problem is I wish to biwire and have an opportunity to buy a 6 foot pair. The question is this: Can I run both 10 foot cables to the left speaker and run the 6 foot pair to right without any wierd effects like "ghosting" or have one channel be clearer or louder than the other? Any ideas? Thanx

Theaudiotweak...Not to belabor the point, but a 20KHz wave traveling at 916 Million ft/sec is 45,000 ft long (about 8.7 miles). Ten feet represents 0.000218 of a wavelength, and corresponds to a phase angle of 0.078 degrees.

My brain/ears are not that good!

This is an example of misapplied science so prevalent in audiophile circles. True, science says that there will definitely be a phasing discrepancy, but a very little bit of math (conveniently neglected) shows that it is completely inaudible.
You cannot hear time and phase errors while your speakers swing free air like a pendulum. Tom
Theaudiotweak...Why not? Don't the instruments move around a lot while they are being played and recorded?
Theaudiotweak...Tom...there are several quite straightforward questions that you are avoiding answering, (criticizing my system or my ears instead). Come on: give it a try.

1. When a speaker weighing 50 pounds or more, is suspended by three feet or more of chain, so that its natural (Pendulum) frequency is 1 Hz or lower, how can this frequency be excited by vibrations at 20 Hz, and up? (In other words: what makes you think the darned speaker will move?)

2. What about the instruments moving around as the musicians play them? Why isn't this more significant than speaker motion?

3. What about the fact that midrange sound is radiated by a cone that is moving 1/4 inch or more to reproduce the lower frequencies, and/or moving at subsonic frequency (unrelated to the music) due to record warp?
