A quick bit of background. This Christmas I was gifted a very cool little TEAC CR-H101 CD receiver. I popped on here about a week ago to solicit some recommendations for speakers to make the most of the receiver's relatively meager 20W/channel Class D amplifier. After some outstanding advice from the members here, I ultimately decided to go with a pair of Klipsch RP-160Ms. Well, they have arrived and even with only a few hours of time on the speakers, I am beyond thrilled with what is possible today for less than a grand all in. I just listened to Dire Strait's live Alchemy album and you couldn't wipe the smile off my face. The accuracy of the sound reproduction is certainly remarkable, but it's the quality of the soundstage imaging that really has me floored. It's the case then, that I could be very content with this set up, as is, for a very long time. At the same time, the TEAC receiver does have a subwoofer output. While I find the RP-160M's 6.5" woofer to be very competent, are there any subs out there that you think might serve as a nice compliment to the Klipsch speakers? I stress the word "compliment", because as I say, I very much appreciate the reference type sound accuracy of these speakers. But if there was a sub with a reputation for adding a little bass emphasis that was very tight, refined and extremely well composed, I certainly be willing to consider it. I'm a classic rock/metal guy for the most part, so all I'd really be looking for is maybe just a little more super clean pop on Neil Peart's kick drums or Geddy's bass. And if that's an unrealistic expectation, then I'm happy to hear that, as well. The room in question is roughly 12' by 15' and the Klipsch speakers are on stands about 7' apart and maybe 8' or 9' away from my primary listening position. If purchased, the sub would be set down low, against the back wall, pretty much centered between the RP-160Ms and maybe another 6' behind them. One thing I'm not sure about is if a powered subwoofer would be called for here, or if the TEAC receiver is intended to provide the power. And if it's the latter, does this detract from the power that's available for delivery to the RP-160Ms?
