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

The Klipsch R-51M is a passive two-way bookshelf speaker sold as a pair, built around a 1-inch aluminum Tractrix horn tweeter and a 5.25-inch spun-copper IMG woofer. Its high sensitivity means modest amps and AV receivers drive it to loud levels easily, and the horn tweeter gives it the lively, forward Klipsch sound. It suits stereo and home theater setups where the speakers sit on a shelf, stand or desk. Against rivals like the ELAC Debut 2.0 B5.2 or Q Acoustics 3020i, it is more efficient and more forward in the treble, but less neutral and less forgiving of bright recordings.

What reviewers say

Owners and reviewers generally rate the R-51M highly for its energy, detail and value, calling it a lively speaker that punches above its class. Most criticism centers on the bright, sometimes aggressive treble and the placement demands of the rear port.

What people mention
  • TrebleMixedListeners like the detail and air from the horn tweeter but some find it bright or fatiguing on harsh recordings.
  • SensitivityPraisedOwners say the speakers get loud easily from small amps and AV receivers.
  • BassPraisedReviewers note solid low-end for a 5.25-inch woofer, though a subwoofer still helps for home theater.
  • PlacementMixedThe rear port and horn need some distance from walls and careful toe-in to sound their best.
  • BuildPraisedOwners describe the cabinets and finish as solid and well made for the class.

About the Klipsch R-51M Bookshelf Speakers Pair

The Klipsch R-51M is a pair of 2-way bookshelf speakers. They can be used for stereo listening or in a home theater as front, rear or surround speakers.

Each speaker has a 1" aluminum LTS (Linear Travel Suspension) tweeter paired with a 90° x 90° Tractrix horn. The 5-1/4" copper-spun injection molded graphite (IMG) woofer is light and rigid, which keeps cone breakup and distortion low. The woofer is magnetically shielded.

The cabinet is bass-reflex, with a rear-firing port that is flared to minimize turbulence. It has a wood grain vinyl finish and removable grilles. 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 Klipsch R-51M speakers need an amplifier?
Yes. They are passive speakers with no built-in amplification, so they need a stereo amp or AV receiver. Their high sensitivity means even low-power amps can drive them loudly.
Can I use the R-51M as home theater surround speakers?
Yes. The pair works as front, rear or surround speakers in a home theater, and the horn tweeter keeps dialogue and effects clear.
How do they compare with the Klipsch R-41M?
The R-51M has a larger 5.25-inch woofer versus the R-41M's 4-inch, so it plays deeper bass and moves more air. The R-41M suits very small spaces better.
Do I need a subwoofer with the R-51M?
For music in a small room, many owners are happy without one. For movies or larger rooms, a subwoofer adds the low bass these bookshelf speakers cannot produce.
Where should I place them?
Put them on stands or a shelf with the tweeters near ear height, angled toward the listening spot. Leave some space behind the rear port so bass does not get boomy.
What is in the box?
The pair includes two R-51M speakers, grilles and the manufacturer's warranty paperwork. Speaker wire and stands are not included.
