Do speaker wires have to be the same length for each speaker?

if the right/left length differential is greater than 5% it will ruin the stereo imaging

if greater than 15% it will void the warranty on your speakers

if greater than 25% it will be may cause a short circuit in your power amp

if greater than 40% it will be a fire risk and you should only listen to music with nomex suit on and fire extinguisher in hand
