Massive power not required
Crutchfield Customer Review (What's this?)
I never thought I'd buy Polk, I always figure I'd have to go with some high-priced British or obscure audiophile brand. I've been listening to these outstanding speakers for over a month now, and am still wowed by their detail, lack of coloration, total lack of "boxiness", and evenness of frequency response. With good source material on CD or LP these speakers will sound stunning. What is most impressive is that you don't have to crank the volume to ear-busting levels to get listening satisfaction out of these speakers. And with a good-quality amp driving them you don't need 3-digit wattage to fill a room with sound. My previous-generation Marantz PM6004, conservatively rated at 45W/Channel at 8 ohms, can run you out of the house with these speakers while sounding clean and balanced. With that amp running in Direct Mode with no EQ, I find these speakers to lean just a bit more towards bass-emphasized than bright, perhaps because the bass from these speaker is incredible when the recording provides it, and partly because the Marantz tilts that direction. These big speakers produce a BIG soundstage (not talking about imaging, but rather about their "presence"). Put on some well-recorded orchestral music and you get the full symphony orchestra in your room. I'm sure I could have spent much more and not been more satisfied that I am with the RTi A9s.
Pros: Total lack of coloration, superb detail and balance, good sound at any volume. No excessive sizzle from the tweeter, no frequency overemphasized. You don't need a massive amp, just a good clean one. Absolutely beautiful in the cherry finish. Great for any music genre. Even your spouse will hear the difference, so spend the money.
Cons: Not for small rooms or apartments, they pump out a lot of volume. A bit subdued in the vocals. Very, very heavy with nothing to grab onto to move them around. Should have bought them years ago.
