It took me two months to finally get these new Polks in as they were just released and are the updated version of the last RTI 12. As you can see from the pictures these are very large towers. I have had the chance to hear the RTI 10’s but not the 12’s so this is not a comparison between the two. What I can say about the new 9’s is they do hit hard down low…specs say 18 hz. and they do it with authority.
I started off with a Marantz 7002 powering the A 9’s and progressed up to 200 watts per Chanel then bridged 400 via a separate amp. The A9’s did very well with just a receiver feeding them juice but did come alive with 200 watts. Not sure why people say you could use up to 4oo and 500 watts, I found 200 to be perfect. With the amp bridged sending 400 watts I just could not turn the receiver up as much before the speakers hit there limit which was about -15 db and -5 with 200 watts. Using the flip scene in transformers the A9’s with just the receiver hit very hard and could be felt through the couch. Running 200 watts to them amazed me in there performance down that low.
Personally I would not get the A9’s unless you were not planning on running a separate sub and had a higher end receiver or separate amp to use. I feel that the three 7″ drivers would go to waste when running another sub. At least that’s how it sounded in my room.
Mids and highs had that signature Polk sound (very detailed) and improved to my liking with a little break in time. We are happy to carry Polk audio products and have began incorporating them with great success in our home theater packages. We have recently used Polk in two Seattle home theater installations. Both customers were very pleased.
