Klipsch RP-600M II: 6.5-inch horn-loaded bookshelf pair, the step up from the RP-500M II

The RP-600M II is the larger bookshelf in Klipsch’s Reference Premiere II line. It uses the same kind of horn-loaded design as the RP-500M II (a 1-inch titanium LTS tweeter on a 90 x 90 degree hybrid Tractrix horn) with a larger 6.5-inch Cerametallic woofer and a rear-firing Tractrix port. Klipsch lists 44 Hz to 25 kHz (±3 dB), 8 ohms nominal and dual aluminum binding posts. Our RP-500M II review roundup shows how Erin’s Audio Corner measured the smaller model.

What to know before you buy

  • Sensitivity: Klipsch lists 94.5 dB at 2.83 V / 1 m. Erin’s Audio Corner measured 86 dB, so do not count on a tiny amplifier.
  • Bass: Klipsch quotes 44 Hz (±3 dB), lower than the RP-500M II’s 50 Hz, thanks to the larger woofer.
  • Treble: Erin calls it one of the more neutral Klipsch speakers but measured a treble boost starting around 8 kHz. He suggests turning the speakers about 20 degrees out, facing into the room, or using the grille to reduce the high-frequency tilt.
  • Binding posts: dual aluminum posts, so bi-wiring and bi-amping are possible.
  • Size and weight: 15.75 in high, 7.95 in wide, 13.00 in deep (40.0 x 20.2 x 33.0 cm), 18.1 lb (8.2 kg) each. Use sturdy stands.

Who it’s for

Listeners with a medium or larger room who want the dynamic Klipsch sound with more bass than the RP-500M II, as a stereo pair or as front speakers in a home theater. Alternatives we sell: the RP-500M II, the Polk Signature Elite ES20 and the HiVi-Swans D3.1 MkII.

Who should skip it

Skip it if your room is small and the RP-500M II is enough, or if you prefer a laid-back tonal balance. Owners report that Klipsch horns sound bright with harsh amplifiers or poor recordings.

Common questions

What amplifier should I pair with it? Klipsch’s sensitivity rating is generous (94.5 dB against 86 dB measured), so choose an amplifier with real power rather than a very small one. See our Class D amplifier guide for amplifiers we sell.

Which warranty applies? Klipsch gives a 5-year limited warranty on passive speakers, valid when bought from Klipsch or an authorized dealer, so confirm the seller before you buy.

What reviewers report

  • More neutral than most Klipsch speakers. Erin's Audio Corner calls it one of the more neutral Klipsch models, with a treble boost starting around 8 kHz.
  • Larger woofer and lower bass than the RP-500M II. Klipsch lists 44 Hz (±3 dB) against 50 Hz for the smaller model.
  • Dual binding posts allow bi-wiring or bi-amping.

Critical notes

  • Sensitivity is lower than the rating. Klipsch lists 94.5 dB; Erin measured 86 dB. Plan for an amplifier with real power.
  • Treble. Erin suggests turning the speakers about 20 degrees out or using the grille to reduce the high-frequency tilt. Klipsch horns can sound bright with harsh amplifiers or poor recordings.
  • Size. At 18.1 lb each they need sturdy stands, and the rear port needs space from the wall.
  • Confirm the model and the seller. Make sure the listing is the II and that the seller is Klipsch or an authorized dealer, or the 5-year warranty may not apply.
