Our take on the Klipsch R-51M Reference Bookshelf Speakers

The Klipsch R-51M is a two-way bookshelf speaker sold as a pair, built around a 1-inch aluminum LTS compression tweeter in a 90° x 90° Tractrix horn and a 5-1/4-inch copper-spun IMG woofer. Its 93 dB sensitivity and 8-ohm load make it easy to drive from modest amps, and the rear port adds bass for a cabinet this size. The horn-loaded tweeter gives the lively, forward Klipsch sound that owners either love or find bright. It suits stereo listening and home theater fronts or surrounds; against neutral rivals like the ELAC Debut or Q Acoustics 3020i it trades flatness for dynamics and efficiency.

What reviewers say

  • 4.6 / 595 ratings

Owners rate the R-51M highly, praising its punch, clarity and easy amplification. The recurring complaint is the bright, forward treble, and some note the rear port limits placement.

What people mention
  • SoundPraisedOwners describe a lively, detailed sound with strong dynamics for the size.
  • TrebleMixedSome find the horn tweeter bright or harsh; others call it crisp and clear.
  • BassPraisedReviewers say the rear-ported cabinet produces solid bass for a bookshelf speaker.
  • AmplificationPraisedThe high sensitivity means modest receivers drive them to loud levels easily.
  • PlacementCriticisedThe rear-firing port needs distance from the wall, which limits tight placement.

About the Klipsch R-51M Reference Bookshelf Speakers

The Klipsch R-51M is a 2-way bookshelf speaker sold as a pair. It can be used in a dedicated stereo setup or in a home theater as a front, rear or surround speaker. The cabinet has a wood grain vinyl finish and removable grilles.

A 1" aluminum LTS (Linear Travel Suspension) tweeter is paired with a 90° x 90° Tractrix horn. The 5-1/4" copper-spun injection molded graphite (IMG) woofer is magnetically shielded.

The bass-reflex cabinet has a rear-firing port. The port is flared to reduce turbulence. The 5-way binding posts accept banana plugs (single or dual), pin connectors, spade lugs and bare wire up to 10AWG. Two plastic caps must be removed to use banana plugs.

Questions and answers

Do the R-51M speakers need a subwoofer?
Not for most music, but their response reaches down to about 62 Hz, so a subwoofer adds weight for movies and bass-heavy tracks.
Will a low-power receiver drive them?
Yes. At 93 dB sensitivity and 8 ohms, they reach loud levels from modest amps, though Klipsch rates them for up to 340W peak.
Can I use them as home theater surrounds?
Yes. Klipsch positions them for stereo mains or as front, rear or surround speakers in a home theater.
How far from the wall should they sit?
The port fires from the rear, so leave some space behind the cabinet for clean bass and airflow.
What is in the box?
A pair of R-51M speakers with removable grilles; speaker wire and stands are not included.
Are they good for near-field desktop use?
They work, but the forward horn treble and rear port suit a room with some distance and wall clearance better than a tight desk.
Where is the Klipsch R-51M Reference Bookshelf Speakers cheapest?
At Amazon, for $289.99, 21% under what the other stores charge, as of our latest check.
