I listened to Polk RTi A9's yesterday for a couple hours at Fry's in Burbank, CA. They were set up in a closed theater room, so the sound environment was pretty good. I compared them against the LSi 25's in the same room (which is a poor comparison since they have powered subs in them).
Unfortunately, I havent' listened to enough speakers to give any sort of review, I just know I liked them enough to try an demo them in my home later on. They supposedly sound similar to the RTi12's, which are only 800 a pair at Fry's right now. That's what brought me there in the first place.
I much prefer the rounded cabinet of the RTi A9, to last year's RTi12's rectangular cabinet, but I doubt I'd pay twice as much for it.
I plan to go back next week when supposedly the RTi A9's and the RTi12s will be set up next to each other.
