Iconic Klipsch Sound with Horn-Loaded Technology

At the core of the Klipsch R-51-M is the brand’s signature 90° x 90° Tractrix horn technology. This proprietary horn design enhances high-frequency response and imaging while reducing unwanted reflections from walls or other surfaces. The result is clear, precise sound that maintains its focus even at high volumes.

The R-51-M features a 1-inch aluminum Linear Travel Suspension (LTS) tweeter housed within the Tractrix horn. This tweeter is engineered for high efficiency and reduced distortion, delivering crystal-clear highs and an accurate representation of vocals and instruments. LTS tweeters are a hallmark of Klipsch’s top-tier speakers and contribute to their industry-leading detail and dynamics.

Deep, Tight Bass from a Compact Woofer

Complementing the tweeter is a 5.25-inch copper-spun Injection Molded Graphite (IMG) woofer. Lightweight yet rigid, this woofer is designed for deep, responsive bass and minimal distortion. It delivers a tight low end that enhances movie soundtracks, music, and gaming audio alike.

Together, the woofer and tweeter provide a wide frequency range and balanced performance. The Klipsch R-51-M offers a frequency response of 62Hz to 21kHz, delivering both the thump of low-end notes and the crispness of high frequencies with confidence.

High Efficiency and Impressive Power Handling

One of the defining characteristics of the Klipsch R-51-M bookshelf speaker is its high efficiency. With a sensitivity rating of 93 dB at 2.83V/1m, these speakers can produce powerful sound with relatively little amplifier power. This makes them a great match for both entry-level and high-end receivers or amplifiers.

The R-51-M supports up to 85 watts RMS and up to 340 watts peak power, allowing it to perform well in both compact stereo systems and more demanding home theater configurations. Whether you’re watching an action movie, streaming high-resolution music, or listening to vinyl, these speakers deliver consistent and dynamic audio.

Engineered for Versatile Placement

Measuring just 13.3 inches tall, 7 inches wide, and 8.5 inches deep, the Klipsch R-51-M bookshelf speaker is designed to fit comfortably on a shelf, media console, or speaker stand. Despite its compact size, it offers a surprisingly expansive soundstage and impactful performance that can fill medium to large rooms with ease.

Its rear-firing port is precisely tuned to enhance low-frequency response and minimize turbulence, but it’s important to provide a few inches of space behind the speaker for optimal airflow. The speaker features sturdy MDF cabinetry with a scratch-resistant textured wood-grain vinyl finish that adds a touch of sophistication to any room.

Build Quality That Matches Performance

Klipsch is known for combining high-performance sound with durable construction, and the R-51-M is no exception. The cabinet is built from reinforced MDF to reduce vibration and cabinet resonance, which helps ensure cleaner sound reproduction.

A magnetic, low-profile grille is included for a sleek, minimalist look while offering protection for the drivers. The gold-plated 5-way binding posts support a wide range of connection options, including banana plugs, spade lugs, and bare wire, making setup easy and secure.

Ideal for Multiple Audio Setups

The Klipsch R-51-M bookshelf speaker is highly versatile and integrates well into a wide variety of home audio systems. It can serve as a pair of dedicated stereo speakers in a high-quality two-channel music system or function as front or surround channels in a multi-speaker home theater setup.

Many users pair the R-51-M with a powered subwoofer to extend the low-frequency response for a more immersive experience. It also works seamlessly with Klipsch center channels and floor-standing speakers from the Reference series to build a cohesive soundstage in larger systems.
