RTi A9- Great sounding speakers.

I have 2 pairs of these beauties,I`m running these with 2 2chnl amps.I have ea. pair hooked to my Perreaux amp 350 watts per chnl ea amp.With the 4 playing in my 280 sq.ft. living rm. you would think your actually at a live concert. I have 2 12" 500 wt rms subs hooked to my system,Wow do my windows shake,between the 4 A9s & the 2 subs which I really don`t need ,these 4 polks put out enough bass to annoy my neighbors on either side of me.Over all great speakers,I don`t understand why the newer A9s cost almost half the price of the older model the RTi12s. I had a pair & I think the A9s are nicer. My vote B+ Thanks Pete

Sound is crisp and clear. Just make sure you have a good amp to make this babies perform. This is a 500 watts speakers and require substantial power amp.

Love THEM! my second pair of my 2nd system!

Yes , my second pair of these, love them, first pair for my 7.4 Onkyo txnr-828 receiver, I also use mission 33i,34's, and 4 subs, 3 bic 475watt ones and polk 440, with klisph bi-polar back surrounds/Energy Veratas centre Panisonic zr 65'' reference plasma,yes this system rocks! great for movies, remastered cd's, hd dvd's , music hall player-l-bums. Second system upstairs, 7.2 system with 7 channel speaker box, full surround! lol The music sounds like a concert with my Polks a9's Boston more than a feeling rocked my large living room, gee felt like I was back in high school!, Buy these you need a good receiver that puts out, if you don't bi-amp them , other wise they are great! Good looks and very modern, first pair , I just read reports, then bought them on sale on Boxing day, second pair got them on sale again just recently when I saw them on line, best speaker if you want nice mids and great sound, you can mix them with other speakers too, like I did with Missions and Paradigms, and klisph horns, try them out with the Xmen movies or Iron man, you will love them, they will rock your rooms! Have fun,,,,,,the mystro!

Those speakers are simply amazing. I bought them during the boxing day period with less than half of the regular price. Worth every penny. I must say, those speaker are very heavy. I use them with a marantz. I must tell you guys, you haven't heard anything until you plugged them with the BI-AMP configuration. The improvement is astonishing.
