Klipsch RB51 5.25" Reference Series Bookshelf Loudspeaker Pair (Black Ash)

• High-performance bookshelf speaker
• Rear-firing port
• Tractrix® Horn eliminates acoustic interference from shelf installations

Exclusive Tractrix® Horns have always been the key component of this critically acclaimed series. In the RB-51, this technology has been refined to include improved throat geometry for a more genuine, lifelike sound. Behind the horn lies a 1-inch titanium tweeter with a powerful neodymium motor structure to provide a unique combination of precision, clarity and effortless dynamics.

The RB-51 employs a 5.25-inch woofer for a solid bass foundation. This Cerametallic™ woofer with inverted copper dust cap exhibits a very high stiffness-to-mass ratio and superb damping characteristics.

Increased baffle ribbing around the horn mouth dramatically improves acoustics across the sonic range. For signal purity and perfect driver integration, the crossover on the RB-51 features the finest components and Klipsch custom internal wiring.

Available in a black woodgrain vinyl finish, the RB-51 comes with a low-diffraction, magnetically attached grille to further accentuate the elegance of this speaker.
