Description

The Klipsch Reference R-40M pair are high-performance bookshelf speakers designed to deliver detailed, dynamic sound with clarity and power in a compact form factor. Part of the Klipsch Reference series, each speaker features a 1″ aluminum-dome tweeter mated to a Tractrix® horn, which improves efficiency and directs crisp, clear highs with enhanced dispersion for lifelike soundstage imaging. The 4″ spun-copper IMG (Injection-Molded Graphite) woofer produces rich midrange and punchy bass that belies the speaker’s compact size, offering balanced audio across music and home theater content.

Klipsch’s signature Tractrix® port technology reduces air turbulence and distortion, enabling cleaner low-frequency performance and improved overall dynamics. The rigid, acoustically optimized cabinets are engineered to minimize resonance and coloration, enhancing transparency and allowing you to hear fine details in vocals, instruments, and soundtracks. With high sensitivity and efficient design, the R-40M speakers can be easily driven by a wide range of amplifiers and AV receivers, making them a versatile choice for both two-channel stereo systems and surround sound setups.

Finished in a sleek Black woodgrain vinyl with removable magnetic grilles, the R-40M pair combines premium aesthetics with robust build quality that fits seamlessly into any living space. Whether you’re listening to your favorite albums, watching movies, or gaming, these bookshelf speakers provide engaging audio performance with surprising depth, clarity, and presence from a space-saving design.
