Infinity ERS 110/Polk 80i

[kunupatil]

I am looking for 2 pairs of in-ceiling speakers, shortlisted on infinity ERS 110 and polk 80i. Only criteria I used is price range. They are about the same price, It is just that for paying $50 extra for polk, i would also get $199's subwoofer free at crutchfield. I could not find any place to check how these speakers sound and also no website that reviews this speakers, Can anyone out here tell me how these speakers are, or a store where I can listen to them, I am in Tampa, FL, I have Yamaha RX-V2400 receiver.
Thanks in advance.
