A towering achievement in a bookshelf design,
the Reference Series RB-81 delivers unrivaled
audio performance for those who demand the
very best. With its high-end materials and
cosmetic elegance, this flagship model is
definitely a force to be reckoned with.
Exclusive Tractrix®Horns have always been the
key component of this critically acclaimed series.
In the RB-81, 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 large ceramic
motor structure to provide a unique combination
of precision, clarity and effortless power.
The RB-81 employs an 8-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.
The RB-81’s front-firing port eliminates
turbulence noise and makes installation into
custom cabinetry a breeze. 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-81 features the finest
components and Klipsch custom internal wiring.
Available in either a cherry or black woodgrain
vinyl finish, the RB-81 comes with a low-
diffraction, magnetically attached grille to further
accentuate the elegance of this speaker.
