    • WOW, Stunning

      from Courtice, Ontario on February 15, 2019

      I just bought a pair; along with Polk's same series matching center, pair of rears, and their HTS 12" sub. I am blown away - these RTIA9s are unbelievable - that is to say that they have exceeded my expectations already, and I haven't even bi-amped them yet. Dimensions of sound beyond my dreams; it's like I am hearing ever song in my library again for the first time.

    • Joke

      from Walkerton on. on January 28, 2019

      Been trying to buy this pair, for a while now. When they go on sale, there out of stock, What a joke. I will no longer shop here.

    • Excellent Speaker

      from Victoria, BC on January 12, 2019

      I have a older set of Polk Monitor 12 series 2 speakers and was hesitant to try a new speaker. After a few weeks with these I can say that I'm very happy with the sound separation, bass and detail these speakers provide.
