  • you cant just use any Receiver... these need big power

    from Toronto on June 8, 2019

    these are FANTASTIC loudspeakers if you give them BIG wattage!... they need a minimum 250watts RMS to shine. 150watts or any Receiver WILL NOT DO! Dont waste your money if you cant afford to give these a big integrated amplifier or power amplifier!

  • Awesome speakers

    from SK on May 29, 2019

    The wattage requirements are high for these, so don't even think about hooking them up to any 5.1/7.1 reciever. I have the hooked up to a behringer class d power amp at 500w per side just to drive the subwoofers. And 2 other class A B power amps bridged for 560 w per side to make them really come to life. Best used with an aditional DAC / pre amp. I bought them on sale too, had no idea what I was getting my self into. Now I'm more then 2 grand in it on top of the cost of the speakers just to power them correctly. All worth it though

  • 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.
