Uneven speaker wire runs

It's odd, isn't it, that an audio signal doesn't travel at the speed of sound.

Equal length cables are easier to re-sell later.

It doesn`t matter a whit in 2 channel either. 186,000 mi./sec. divided by 11 ft. Do the math. The laws of physics are the same for HT or 2 channel.

The possible difference doesn't have anything to do with the speed of the signal but POTENTIALLY with the inductance,resistance and capacitance of the cable.
In reality it's probably fine!

Tarsando, an "audio" signal doesn't travel the speed of sound when it's in the wire because it's an "electrical" signal at that point. It doesn't become an audio signal and travel at the speed of sound until the electrical energy is converted into acoustical energy at your speakers. I think you knew that however.
