Product Research

Features

1" Horn-Loaded Tweeter: The R-51M bookshelf loudspeaker features Klipsch's proprietary Tractrix Horn technology mated with a 1" aluminum LTS tweeter, for impressive high-end response and greater extension, enhanced imaging and powerful dynamics.

  • 90°x90° Tractrix Horn: The square Tractrix Horn delivers a 90° (w) x 90° (h) dispersion pattern for a broader sound-stage. Klipsch exclusive Tractrix horn technology ensures that the speaker's high frequency energy is aimed at the listener and reduces artificial reverb or filtering caused by indirect sound bouncing off of walls. Using this proprietary focused technology provides clarity, dynamics, and detail for your movies and music
  • LTS (Linear Travel Suspension): Behind each horn lies a 1.0" tweeter with a linear travel suspension. Klipsch exclusive Linear Travel Suspension (LTS) minimizes distortion for enhanced, detailed performances. In addition, Using Kapton (an extremely light and rigid material) in the tweeter suspension provides high efficiency and improve resolution and detail.

5.25" Copper-Spun IMG Woofer: The Klipsch R-51M bookshelf speaker houses a single 5.25" Copper-Spun IMG woofer. The Copper-Spun IMG (Injection Molded Graphite) woofer is exceptionally light while being extremely rigid - providing remarkable low frequency response, with minimal cone breakup and distortion.

Flared Port: The Klipsch Reference series bookshelf speaker features a rear-firing port that is perfectly matched to the cabinet and drivers. The port is precisely flared to minimize turbulence even at the lowest frequencies.

MDF Cabinet: The Klipsch R-51M bookshelf speaker features a MDF cabinet with a scratch-resistant, textured wood grain vinyl that seamlessly integrates into almost any room or decor. The enclosure's reinforced MDF construction reduces cabinet vibration for less audible coloration and improved sonic accuracy.

Acoustically Transparent Grille: The Klipsch R-51M bookshelf speaker comes with a removable, black cloth grille that is magnetic and acoustically transparent.

5-Way Binding Posts: The Klipsch Reference series bookshelf speaker is fitted with sturdy 5-way binding posts to ensure a secure connection to many types of cable and connectors. The 5-way binding post terminals will accept banana plugs (single or dual), pin-connectors, spade-lugs and bare wire (up to 10AWG). Two plastic caps will need to be removed to use banana plugs.

Mounting Options: The Klipsch R-51M can be placed on a speaker stand, bookshelf, table, or other flat surface. The bookshelf loudspeaker comes with self-adhesive rubber feet to secure the speaker in place and prevent any damage to your stand's or shelf's surface. The rubber feet add approximately 0.3125" to the overall height of the speaker.

Note: There is no included bracket, keyhole slot, or threaded insert to wall-mount the speaker.

Application & Placement: The Klipsch R-51M bookshelf loudspeaker can be used in a dedicated stereo application or in a home theater application as front and/or rear speakers.

  • Front Placement: For optimum performance in a stereo application or as front speakers in a home theater application, Klipsch suggests placing the loudspeakers 6' to 15' apart. They may also be toed-in slightly for better stereo imaging. The listening position should be about 1 to 1.5x the distance separating the speakers.
  • Rear Placement: When used as surround speakers in a home theater setup, the loudspeakers should be placed approximately 2' above the listening position. Typically this will be approximately 5' to 7' above the floor. The surrounds should be placed on the walls directly adjacent to the listening position. Another option would be on the wall behind the listening position.

Reference Series: The Klipsch Reference series consists of four floorstanding speakers (R-610F/R-620F/R-820F/R-625FA), two bookshelf speakers (R-41/R-51M), two center channel speakers (R-34C/R-52C), and one Dolby Atmos speaker (R-41SA) - all sold separately. The Klipsch Reference series line-up of loudspeakers sound great in stereo and home theater applications.

Optional Powered Sub: For bigger & deeper bass response, pair the Klipsch Reference series loudspeaker with one of Klipsch's powered subwoofers (sold separately).

Recently saw a video by Steve Guttenberg who was talking about this very speaker, so clearly the speaker gods wanted me to have them..."right?". Plus, I've never had a set of Klipsch speakers and for "half price", it was worth the gamble. [ M  Nov 15, 2018 ]

Q
How do these compare to the R-15M? Is it worth upgrading to these?
[ Jay  Nov 25, 2018 ]
8 answers
A
it depends more on price. at the price i paid for the R-51's (124.99), it's worth picking them up on their own! the sound is terrific!
[ brian  Dec 03, 2018 ]
A
Not familiar with the R-15M, but I'm very pleased with the R-51M speakers. My only suggestion would be if you are going to get the R-51Ms, make sure you have a decent subwoofer or pair them with another set of speakers with a substantial low end. I have my R-51Ms paired with a set of Elac B6s "and" an old Infinity sub. My goal with buying the R-51Ms was to raise the ceiling of the highs and enrich the mids that my Elacs were lacking. Adding the sub just rounded out the bottom end and really added some extra bass punch. I read somewhere that a great way to get better performance from your speakers without spending a fortune was to pair two sets of speakers that have different strengths. I can verify that my "Budget Wall-0-Sound" kicks ass and it didn't have to sell any of the kids to do it. (Though I've been tempted) If the half price sale is still going on, take advantage and pick up a pair of these. Hell, you can always send them back if you don't like them. But I think you will want to keep them. Cheers!
[ M  Dec 03, 2018 ]
A
I Think the 51 IS JUST A NEWER MODEL THE 15 THE LOOK ALMOST THE SAME WITH SOME MINOR DIFFERENCES THE SOUND ON THE 51 SEEMS A LITTLE BETTER BUT OVER ALL IF YOU HAVE THE 15'S SAVE YOUR MONEY FOR NOW.
[ LATHROP  Dec 03, 2018 ]
A
Well if your referring to the R-15pm. I'm not sure the R-15pm are powered speakers. The R51m are not. I haven't heard the 15pm's so I can't give you an honest answer. But I'm using four 51m's as my surround and surround backs, and I'm using an Emotiva power amplifier with a Marantz pre amp and they sound amazing. For both movies and music. You won't be disappointed.
[ Jorge  Dec 03, 2018 ]
A
Never heard R-15M so don't know
[ DSE  Dec 03, 2018 ]
A
The R-51M seems to be the same speaker as the R-15M judging by the speaker specs.
[ Darren  Dec 03, 2018 ]
A
I can't answer this question as these are a Xmas present for somebody else.
[ Steve  Dec 03, 2018 ]
A
Sorry, I've never heard the 15's.
[ Gregory Scott  Dec 03, 2018 ]
Q
Can these be mounted on the wall?
[ Mike  Nov 21, 2018 ]
2 answers
A
I don't have an answer for that. Sorry. I plan to have them eventually on pedestals for better sound production.
[ Howard V.  Nov 24, 2018 ]
A
Yes with just a single nail or screw, but these guys are big. I'd recommend keeping them on shelf or at the very least hang them on a stud.
[ William  Nov 22, 2018 ]
Q
can you use banana plugs on these speakers?
[ Liam  Nov 01, 2018 ]
5 answers
A
Yes.....They might be a little tight.Connect carefully. Jazz on!!
[ LUIS A  Nov 02, 2018 ]
A
i believe it is possible. my receiver does not accept banana plugs so i do not have them on my setup but there are holes in the posts
[ Rylan  Nov 02, 2018 ]
A
Yes the terminals have the removable caps where banana plugs would go.
[ John  Nov 02, 2018 ]
A
Yes you can
[ Jorge  Nov 02, 2018 ]
A
Yes.
