So you could say using lower ohm speaks contencrates the energy-- somewhat like force per sq inch? And this does what? makes the speakers louder?

if this is so or not..why are so many oohs and ahhs about lower impedance?

When I was younger loud music was definatley the thing...in my ripe 30's he ehehe louds is fun but not th norm. Which suggest good speakers at low levels are very nice indeed.

But any way the market is mainly 8 ohm...any particular reason?
