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

Ohm's Law is a handy tool. Learn a little about basic electricity. People who would pay over $50 for 20' of speaker wire are buying a fashon designers idea or a name that says I'm buying the best because it has "your name here" on it. My system sounds real good. Blows out candels and will flap pant legs and I could have spent a lot more money if I wouldn't have gone to school to learn about electronics. When it comes to high end audio, most of the time I think you can buy better but you can't pay more...
