check out a review from customers who bought the Polk Audio RTi series from AMAZON:
Customer review # 1
These are some really wonderful speakers. I auditioned literally dozens of speakers from Polk, Klipsh, Energy, B&O etc. Some of the ones I tested were 10 times the price of these Polks and even excluding price considerations, these were the best I heard (I even enjoyed them more than the more expensive Polk LSi Series).
In the past, I would have said that I prefer loudspeakers with a more rounded, mellow, laid-back sound as opposed to ones that are a bit more forward and precise, but the RTi A7s changed my mind. They are not at all harsh or bright, and while they are very precise, they're not at all fatiguing to the ear. To my ear, these speakers offer a fantastic listening experience for both music and home theatre. And, while you're not buying speakers to look at them, you'll be happy with the real wood finish and superb craftsmanship of the cabinets as well.
Of course, sound quality is somewhat subjective, so you should listen for yourself if you can. However, there's a good reason why these speakers are sold out and back-ordered all across the country: they're really that good. If you can actually get your hands on them, I don't think you'll be disappointed.
Just for reference: I use these about 70/30 for music/TV. I have an Onkyo 876 powering these speakers and have them paired with the Polk MicroPro 1000 Sub, Polk CSi A4 Center and a set of Polk RTi A3s for the surrounds. You don't have to source all your speakers from one manufacturer or series, but the Polks are all "timbre-matched" to ensure seamless sound. (Speakers have "accents" and in some cases--particularly with the fronts and the center channel--mix-and-match speakers can sound harsh). Hope this is helpful.

I got these on a different website, but I cannot sing their praises enough. They, as stated in other reviews, are 42" tall and weigh around 60lbs. I got the cherry ones and my wife couldn't be happier. The all black bachelor pad look just isn't for us, but these nice warm cherry speakers are beautiful.
As with all speakers, they get better with age. That is true for these more than any others I have heard. They start out a bit harsh, so much so that I almost regretted my purchase. Then one day, about a month after purchasing them, I turned on my Denon AVR 890 and something magical happened. The sound was full and warm. I thought my wife had changed some equalizer settings, so I checked...everything was the same. Each and every day that I use these (along with my Denon AVR 890, CSi A6, and RTi A3 surrounds, and PSW 125) whether for movies, music, video games, or whatever, I am overjoyed.
One final thing, and I'm not sure if any other reviewers have discussed this: These are built for two channel audio primarily. There is no reason to spend this kind of money if you just want two fronts for your 5.1 surround sound. The volume and sound quality for 5.1 should be approximately equal across all channels. If 5.1 sound is your game, get the most expensive center channel you can afford (for dialog) and get 4 matching bookshelves for the other channels.
If you want a sound system that can do 2 channel audio as well as 5 channel video, these are the speakers for you.
One final note on the Polk RTi system: If you calibrate it correctly and want GOOD sound (not just boomy bass), your living room will sound better than 90% of movie theaters. IMAX is a different story and some really high end theaters callibrate correctly, but the vast majority think that more bass means higher quality. Get a good HT setup, a PS3 Blu-ray player, and you'll never have to pay $10 for crappy sound again. Consider it an investment.
