Detailed Description

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.
