Trying to keep the price about the same, so I'm considering these two systems. I have to get a receiver as well, so a Denon 2808 would be likely if I got the M80's. Otherwise I've been looking at the Onkyo 605, or the Yamaha RXV3800.

I've always been a fan of 4 ohm speakers, but I'm wondering which would make a bigger impact, the 500 sub or the M80 towers. Thoughts?
