Cable length dilemma!

Ok, so here's the dilemma: speakers placed on either side of a fireplace, impossible to place the amp between them. Only place to put the amp is just to the left of the left speaker, leaving a 1-foot run to the left speaker, and a 9-foot rum to the right speaker. I have always read that your L/R cables should be the same length, but in my case that would necessitate coiling 8ft of the L cable underneath the rack, which is the lesser of two evils here - mismatched length, or a big coil of cable under the rack?

Inductance of straight wire is about 0.2-0.4uH/ft for gages 10-20. In the speaker cable this inductance is greatly reduced because of return wire (currents in opposite directions) especially when wires are twisted (twisted pair or helical twist). Coiling such cable should not increase inductance since magnetics flux created by wires conducting identical currents in opposite directions should be zero, pretty much like in the common mode choke that has close to zero inductance for normal mode currents.

If you believe that speaker wire has any effect on the sound - it will be proportional to length of the wire.
