Just wondering if anyone has any experience with either batch of speakers. I just picked up a pair of Polk R300s on sale for an insane price. I see the Infinity Primus 250's on crutchfield for a really good price also right now though, so I was wondering which everyone thought would be better. If the Infinitys would be a lot better, I may pick them up and use the Polks as my rear speakers. The Infinity 250s are about $150 more per pair than I paid for the Polk since they were on sale for such a low price though.
