R-51M BOOKSHELF SPEAKER (PAIR)
Leveraging a 1" aluminum tweeter matted to our proprietary Tractrix horn-loaded technology - the R-51M bookshelf speaker delivers incredible acoustics to fill your home with loud, crystal-clear sound and robust bass that no ordinary bookshelf speaker can.
TRACTRIX HORN TECHNOLOGY
Klipsch exclusive 90x90º Tractrix horn technology ensures that the R-51M high-frequency energy is aimed at the listener and reduces artificial reverb or filtering caused by indirect sound bouncing off of walls.
WITH KAPTON SUSPENSION
LINEAR TRAVEL SUSPENSION TWEETER
Klipsch exclusive Linear Travel Suspension (LTS) aluminum tweeter minimizes distortion for enhanced, detailed performances. Using Kapton, an extremely light and rigid material, in the tweeter suspension provides high efficiency and improve resolution and detail.
SPUN COPPER IMG WOOFERS
Injection Molded Graphite (IMG) woofer cones are exceptionally light while being extremely rigid – providing remarkable low frequency response, with minimal cone breakup and distortion. When paired with the Tractrix Horn-Loaded LTS Tweeter, it provides speaker efficiency highest in its class.
SLEEK DESIGN
Exposed fasteners, low profile magnetic grilles and a scratch-resistant, textured wood grain vinyl give the Reference Series a polished, modern appearance. Reinforced MDF construction reduces cabinet vibration for less audible coloration and improved sonic accuracy.

Perfect Setup
These R-51M speakers are so clear and fill our 2600sft basement with smooth music! I didn’t want to buy a stereo receiver in addition to the speaker and turntable, so I elected to purchase these active speakers. The setup was seamless and quick. The sound and bass are perfect, with no static or distortion. I love the remote control. I did A LOT of research for bookshelf speakers and read up on articles from several audiophiles. While I’m not a music snob, I am an aficionado and I wanted great sound quality. Don’t let the price fool you, these definitely will fill your needs!

Replaced some old Polk T15s. No comparison
Tested a variety of music on the new Klipsch R-51s (classical, Shoshana Michel, Grateful Dead, The Cure, and some blues). They really shined with Al Kooper’s “Flute Thing” as there are a great number of instruments and solos at work in that song.
Also watched a couple movies and documentaries with the new speakers. They performed well once a couple adjustments were made.
Definitely a lot more detail in the percussion and voices are very clear and defined. I have Fluance bipole rear surrounds and they nicely balance out the Klipsch brightness from the front. The wide dispersion and balanced mids mix well with my front setup and subwoofer.
I got these for a great price and am extremely pleased. Just make sure to have a subwoofer and I suggest making equalization adjustments. The mids are a little finicky, but everybody has different listening tastes.

Fantastic pair for 2.1 stereo or as a high end addition to full surround

Crystal clear audio at very low volumes as well as very loud. They respond excellent to software equalization, capable of some bass on their own if you don't want a full subwoofer with them (highly recommend 10" or larger subwoofer). The sensitivity is such that even a simple amp can drive these very well for an 8ohm passive speaker, which is great for small units or a cottage or apartment.
They're very bright in sound thanks to the horn shape tweeter space, but if you keep the magnetic shields on it attenuate the high end just a little for a personal preference adjustment.
After breaking them in for a week there's no hissing, whine, static, fuzz, or any discernable audio when playback is stopped so careful not to leave them on, there's almost no way to tell just by listening for electrical noise.
These pack a punch, they're very clean in looks and sound, but if you're into warm sound (lows and mids emphasized) rather than bright, clean vocals and instruments this brand may not be your best fit. These are amazing for all types and styles of music, and especially movies / games with that clear high end though, so I'd recommend them to anyone on a budget who wants an upgrade from even the best all-in-one stereos available. Build a system with these speakers and a small amp and you'll have a system to gush over for years to come since these can be added on to any high end home theatre solution at any price range down the line.
