Polk Audio RC60i Vs. RC80i ceiling speakers

Hi guys,

I came across an excellent deal on both these speakers so I'm wondering what the difference is between the two before I purchase.

The RC80i I can get for about $110 and the RC60i I can get for about $90.

To give you an idea of the savings my local futureshop (a.k.a. Best Buy since they're basically the same store) is selling the RC60i for $279.99.

A savings of $190.00/pair!

Anyway, is there really any big difference between the RC60i & RC80i???
