A towering achievement in a bookshelf design, the Reference Series RB-81 II is a force to be reckoned with. It provides unrivaled music and movie performances to those who demand the very best, but don’t have the room to accommodate a floorstanding speaker.
The RB-81 II is complete with our proprietary Tractrix® Horn technology which produces a unique combination of precision, clarity and effortless power. Finished in a beautiful light cherry or black woodgrain vinyl veneer, the RB-81 II is guaranteed to complement any décor.
Now in its fifth generation, Reference II speakers boast enhanced features, including re-engineered drivers and a new crossover system, to capture your attention and excite your emotions. In addition to the improved sound quality, the look of “big sound” has been redefined throughout the line with sophisticated cabinetry, refreshed logos and rounded feet.
