8" Bookshelf Loudspeaker

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.

RB-81 specifications

The Klipsch RB-81 is a revered bookshelf speaker that epitomizes the brand's commitment to high-performance audio. Designed for both music lovers and home theater enthusiasts, the RB-81 delivers exceptional sound quality in a compact form factor. Its sleek design enhances any room aesthetic while providing an immersive auditory experience.

At the heart of the RB-81 is Klipsch’s proprietary Tractrix Horn technology. This innovative design helps to improve the efficiency of the speaker while providing a more focused soundstage. By directing high frequencies in a narrow path, the Tractrix Horn facilitates a clear and articulate sound, ensuring that listeners experience precise detail across all frequencies. Coupled with the titanium diaphragm tweeter, the RB-81 excels in producing crisp high notes, perfect for reproducing vocals and intricate instrumentals.

The speaker utilizes a 8-inch copper-spun woofer, which is integral to delivering a robust bass response. The woofer's design reduces distortion and enhances dynamics, making the RB-81 capable of handling powerful audio tracks without sacrificing clarity. With a frequency response range that covers deep lows to bright highs, this speaker can seamlessly transition between musical genres, providing a well-rounded listening experience.

Another notable feature of the RB-81 is its highly efficient design. Klipsch speakers are known for their high sensitivity ratings, and the RB-81 is no different, allowing it to produce higher sound levels with less amplifier power.

The cabinet of the RB-81 is crafted from premium materials, ensuring durability while minimizing resonance. Available in a stylish wood veneer finish, it can easily integrate into various home decor styles. Additionally, the rear-firing bass port enhances the overall bass response, allowing for flexible placement options without compromising sound quality.

Overall, the Klipsch RB-81 stands out as a formidable bookshelf speaker, highlighting advanced technologies, exceptional build quality, and audio performance that appeals to both casual listeners and audiophiles alike.
