Enjoy crystal-clear sound from these bookshelf speakers

The Klispch® RB-51s deliver rich sound from all your music, movies, and video games. These high-performance bookshelf speakers are part of Klipsch's popular Reference Series — a line of speakers known for its power and accuracy.

Horn technology for dynamic performance

The RB-51 use a horn-loaded tweeter. A flared opening in the enclosure projects high frequencies toward your listening area and prevents sound waves from simply spilling out in all directions. It's the same principle that makes your voice easier to hear when you cup your hands around your mouth. This horn design brings out details in everything you listen to, while reducing reflections that can color the sound. The horn also improves dynamics and efficiency, for powerful, "front row" sound that remains crystal-clear at all volume levels.

High-tech construction

The RB-51's woofer dishes out smooth midrange and articulate, well-defined bass. Klipsch makes the woofer cone out of anodized aluminum, so it's strong yet lightweight. A rigid cabinet with resonance-fighting internal bracing houses both the woofer and the tweeter. It all adds up to remarkably accurate reproduction of all your music and movies.

Build a complete Klipsch system

Use a pair of '51s in a stereo setup, or team them with other Reference Series speakers for high-impact home theater. You can set these speakers on a stand, or use the integrated keyhole slots for easy wall-mounting. Threaded inserts let you attach an optional bracket for even more placement options.
