A head-to-head bookshelf speaker comparison to help you pick the right one for your room.

Verdict
These two sit at the same price and sound nothing alike. The Klipsch uses a horn-loaded tweeter and is far more sensitive, so it goes loud on modest power and has a forward, detailed presentation. The Polk uses a ring radiator tweeter and is smoother and warmer, but wants more amplifier to reach the same level. Buy the Klipsch for home theatre and lower-powered receivers; buy the Polk for long music sessions and brighter rooms.
| Klipsch RP-600M II | Polk Reserve R200 | |
|---|---|---|
| Tweeter | Horn-loaded compression | Pinnacle ring radiator |
| Sensitivity | About 96 dB, very high | About 86 dB, average |
| Amplifier needed | Modest, happy on any AVR | More power to reach the same level |
| Presentation | Forward, detailed, dynamic | Smoother, warmer, more relaxed |
| Room brightness | Can be much in a bright room | More forgiving of hard surfaces |
| Best for | Film, dynamics, high output | Extended music listening |
You are driving them from a receiver rather than a separate power amplifier, you want effortless dynamics for film, or you simply like the horn presentation. Sensitivity that high means the amplifier is barely working at normal levels.

Your listening room has a lot of glass and hard surfaces, or you listen for hours at a time and find horns fatiguing. The Polk asks for more power in exchange for a gentler treble.

Yes, and the gap is large. A ten decibel sensitivity difference means the Klipsch needs roughly a tenth of the amplifier power to reach the same volume. On a mid-range receiver that difference is audible when the film gets loud.
It depends far more on the room than the speaker. In a carpeted room with soft furnishings the RP-600M II is lively rather than harsh. In a room with bare floors and large windows it can be too much, which is exactly where the Polk is the safer choice.
Try not to. Timbre matching across the front three matters more than the absolute quality of any one speaker, because dialogue and effects pan between them constantly. If your centre is Klipsch, stay Klipsch.
