Klipsch RP-600M II vs Polk Audio Reserve R200

The short answer

Neither sheet supports the comparison this pair is usually made on. Both sensitivity figures — 94.5 dB and 86 dB — carry an UNSTATED measurement context in our data, so the 8.5 dB that looks decisive sits between two unlabelled yardsticks and we rank nothing on it. Buy the Klipsch RP-600M II if a stated 1,500 Hz crossover point, a stated horn-compression tweeter and a 44 Hz bass figure qualified at ±3 dB are what you want on the sheet. Buy the Polk Audio Reserve R200 if a stated 3.8Ω minimum impedance — the field a receiver match is actually checked against — and a third finish option matter more, and read the price row above either way, where the Klipsch tracks $99/pair under the Polk today.

Reading the numbers honestly

The sensitivity figures are 94.5 dB (Klipsch) and 86 dB (Polk), and BOTH rows record their measurement context as UNSTATED. An 8.5 dB gap between two unlabelled yardsticks is not an 8.5 dB gap — a half-space or in-room figure reads several dB above the same driver measured anechoically, and neither sheet tells us which convention it used — so this page reports the pair and ranks nothing on it. The Klipsch specification does carry a footnote about half-space anechoic measurement with a 2.83V input, and our row stores 'unstated' because half-space has no enum value in our schema rather than because no source states one; that is a gap in our vocabulary, honestly recorded. Impedance is the next trap: the Klipsch states an 8Ω NOMINAL and the Polk a 3.8Ω MINIMUM, which are different fields answering different questions — the minimum is the one a receiver's rating is actually checked against, and the builder's compatibility check uses it. Bass extension is only half-qualified: 44 Hz at a stated ±3 dB on the Klipsch against 51 Hz whose tolerance our Polk row records as unstated. Power is stated as two different quantities — 400W peak power handling against a 30–200W recommended amplifier range — so those numbers answer different questions too. What matches: 2-way, one 6.5-inch woofer, a 1-inch tweeter, a bass-reflex ported cabinet, bi-wire binding posts and pair pricing on both rows. Only the Klipsch row states a crossover point (1,500 Hz), a tweeter type (horn compression) and a port location (rear).

Still deciding?

• The comparison this pair is usually made on cannot be made from our data: BOTH sensitivity figures — 94.5 dB and 86 dB — carry an UNSTATED measurement context, so the 8.5 dB that looks decisive sits between two unlabelled yardsticks and nothing on this page rests on it.
• Only one bass claim is qualified: 44 Hz at a stated ±3 dB on the Klipsch against 51 Hz whose tolerance our Polk row records as unstated.
• The impedance fields are different in kind, which no spec table puts side by side: an 8Ω NOMINAL figure on the Klipsch against a 3.8Ω MINIMUM on the Polk — and the minimum is the one a receiver rating is checked against.
• Power is stated as two different quantities: 400W peak power handling against a 30–200W recommended amplifier range, so the two numbers answer different questions.
• The cabinets are close and the geometry inverts: 15.8 × 8 × 13 inches and 18.1 lb against 14.1 × 7.5 × 13.9 inches and 19.1 lb — the taller speaker is the lighter one.
• Provenance honesty on the pricing unit: both rows price per pair, but the Klipsch's 'sold as pair' entry is retailer-sourced where the Polk's is manufacturer-stated — $700/pair vs $799/pair as tracked today.
