I have been in the process of replacing my HT speakers, moving away from my piecemeal 5.1 setup (old Altec fronts, Bose surround satellites, Boston Acoustics center channel), to an all-Polk 5.1 configuration. From the research I did prior to actually buying anything, reviews seemed to stress that the RTI-A polk line sounds just about as good as other companies' speakers that typically run for twice the price. After listening to a bunch of options at the now-defunct Tweeter, I came to the same conclusion; I purchased this set of RTI-A7s for fronts, a Polk Audio CSI A6 Center Channel, and Polk Audio RTI A3s for rears. I got the RTI-A7s for a song at Tweeter right before they closed, even cheaper than here or other sites.
These were also the first new items I bought as part of my replacement project, so it really gave me a chance to listen to these in comparison with my old Altecs. I did an A-B test, and the detail and sound field these babies put out really blew away the older, more conventional (and aesthetically speaking much uglier) Altecs (running on a Yamaha RX-V1800). Mid- and High-range detail are exceptional on the RTI A7s, really light years ahead of my old dinosaurs, and perfect for HD formats like BluRay or SACD. The only area where the Altecs win by a slight margin is deep bass (<35Hz) response. But considering the Altec's single, massive 12" woofer as compared with the dual 7" polymer woofers on the Polks, I expected this. Getting a sub solves that problem (I ended up getting a Polk Audio PSW505).
In terms of power handling, these are rated at 300 watts, which I can't really approach with my receiver. At nearly max volume they still sounded great with no degradation in clarity of sound that I could detect.
Look and feel is nice too. They feature a sleek curved cabinet design with a black-oak finish, pewter-accented grilles, and stand about 42". Considering the size and quality of construction, they aren't overly heavy either (~60 lbs.)
These speakers sound equally good with music and movies, having had the chance to test them out pretty extensively since getting them just over a month ago. Another quick note is that when brand-new they sounded a bit bright, but now that I've had time to break them in that issue is gone.
In conclusion, for the money this is a great buy. You're getting a versatile, powerful loudspeaker that is up to the task of handling the super-detailed sounds of today's HD formats, and you're getting it for substantially less than comparable units from other industry leaders. I am beyond pleased with these speakers - Polk may have converted me permanently. Highly recommended.
