I was wondering why subwoofers use tinsel leads to carry the current to the voice coil. Wouldn't copper be better because the resistance to electricity flow is lower? What makes the tinsel leads better for that part of the sub.?

Flexibility/durability.

When you have a cone moving up to a couple of inches 30-80 times a second, it needs to be flexible. Plus they weigh less. You don't want your tinsel leads significantly adding moving mass. and durability, don't want fatigue in the wire from stretching, which may eventually break.

So basically I agree with bromo, just with more words.

Thanks. I was curious about that and now i know.

Ive had tensil problems with a sub before and tried to fix it with some super flexible wire for RC cars, the "fix" didn't last more then a week before they failed again.
