Summary: Bought these 4 years ago and have used them daily since. They are powered by a Parasound Model 2250 (250 WPC) fed by a Parasound 2125 pre amp. My main listening pleasure is music from the late 1940's through the mid 1960's and volume level is such that conversation is not a problem. Speakers are about 6 ft apart and 18" from the wall. My listening position is about 9-10 distant and midway between speakers.
Two years and counting... best speakers I have ever heard.

Summary: But of course, I haven't paid for some more expensive Polk speakers. After more than two years, I continue to marvel about how beautiful the sound is from the RTI A9s I have. I'm bi-amplifying them with a 100 watt Sony ES receiver. This is nothing elaborate or terribly expensive. And what comes out is the greatest sound I have heard from anybody's speakers, anywhere. You would think the sound in an IMAX theatre would put everything else to shame. But not my A9s.
Summary: These speakers do not image well and sound shallow at high volumes.Mid range is awful! Audio processing unit has helped a little. I have replaced 3 mid range speakers, blew them. Polk sent new ones that are gray instead of the original black..Mid range seem to want to explode out of the cabs at around 300 watts. I have read two other audiophile reviews with same complaints. But I'm dumb founded on the good reviews these get?
Summary: I have listened to many speakers over the years, these have great sound, yet are a bit weak on imaging. With the correct surround system, the imaging improves dramatically. These speakers are excellent at producing sound at high volume without any distortion. My kids keep telling me to "turn that down".
Summary: Unbelievable sound, cabinet quality! These things are like a piece of art to look at!! Unlike me to spend this kind of money on a set of speakers, but I'm very satisfied that I did! Wish I were driving it with an amp with a little more punch (these babies can handle 500w continuous) I have them paired with a PA sub-woofer and it adds a great sound for movies as well. Separately these RTi9's are great, low-end thru high-end!
Pros: Everything about them! Probably be the last pair I ever have to buy!
Cons: Can't find anything yet... They seem to get better with time!
Summary: I replaced a pair of Cerwin Vega CLS-215's with these. I was a bit worried when I ordered the A9's, that they wouldn't produce the type of bass I'm used to with the Vega's. These speakers produce PLENTY of tight, thumping bass! I listen to just about everything except country music, and I've put these speakers through a wide variety of music, and they are just awesome all around. Crystal clear, and very detailed they are.
Pros: Very detailed, not bright or muddy at all. Plenty of bass when you want it. Very appealing, and in no way an eyesore.(Cherry finish)
Cons: None. Some people list heavy as a con, but to me this is a pro.
Summary: Let me first begin by letting you know my setup. I have a 2.1 setup with a Marantz 7701 Preamplifier and an Emotiva XPA-2 power amplifier. This amp is a beast and the clean power at 300 watts per channel is really opening these speakers up. I have not tried these speakers with only a receiver, but from other peoples reviews it seems that having an additional power amplifier gives you the true capabilities of these speakers.
Summary: I have been a music fanatic my whole life and I use different speakers for different types of listening. I have my Klipsch Cornwalls on my "Main" stereo. Thats for thumping my wife and kids out of bed on Sunday morning or when I want to get the most sound out of a recording without blistering the paint on the walls. I have a set of 901s in the basement for the drunks and the kids.
Pros: Sound great and I haven't even broken them in yet. Look like a piece of furniture. Too heavy for a burglar.
Cons: Don't leave them for your wife to move by herself or you will get skip for dinner.
