Klipsch Reference Series RB-51 Specifications

5.25" Bookshelf Loudspeaker
Built to the same exacting standards as the
Reference Series floorstanding models, the
RB -51 represents an ideal combination of
technology, performance and design. In fact, this
well-thought-out speaker design will forever
change the way you think about audio.
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.
