Klipsch RP-600M (2018–)

It pairs a 1" titanium tweeter mated to a hybrid Tractrix horn with a mid-bass driver distinguished by its copper-colored cone — the copper cone being a signature Klipsch visual element since the early 2000s. The cabinet is rear-ported, but instead of a conventional round port, it uses a Tractrix-shaped opening. A compressed molded silicon face attaches to the 90x90 Tractrix horn to reduce resonance, and the tweeter is vented. Klipsch also applied its Linear Travel Suspension technology to minimize distortion.

Specifications commonly listed include a frequency response of 45 Hz to 25 kHz ±3 dB, nominal impedance of 8 ohms, and power handling of 100W continuous / 400W peak. Sensitivity is notably high at 96 dB — a full 7 dB more sensitive than the Triangle Borea BR02, meaning it will play considerably louder on the same wattage. The RP-600M is generally regarded as an improvement over the earlier RP-160M, addressing user complaints about that model.

Reception is genuinely split. The high sensitivity means it can be driven to loud levels by very modest amplification — one reviewer noted the RP-600Ms "roared like jet engines" with just 18 watts from a First Watt SIT-3, and played loudly even with an 8Wpc single-ended-triode amplifier. But the out-of-the-box tuning is aggressive: it boosts lows and highs while leaving mids behind, an approach one Audio Science Review participant described as throwing out the rule book. That same reviewer, powering them with a 1000+ watt system, called them "really, really bad sound." Others are far kinder — Tech Review Advisor found the bass output amazing for the cabinet size and called it an overall nice speaker, noting it can easily fill small to medium rooms with an appropriate amp.

The RP-600M remains readily available on the used and clearance markets. New pairs have been seen around $319–$329, with a 5-year manufacturer warranty on new stock. The RP-600M II, a later revision, is a separate model covered elsewhere in this archive.
