A powerful performer

Looking for a floor-standing speaker that blends power and performance? Each Klipsch R-820F boasts dual 8" woofers for thunderous bass and warm, clear mids, plus Klipsch's signature 1" horn tweeter for crisp, extended, highs. But you don't have to take our word for it.


Tractrix horns enhance highs and lows

We're used to seeing the Tractrix horn on the front of Klipsch speakers, where it enhances high notes from the tweeter. These speakers use them to improve bass, too.


Look around the back, and you'll see that instead of the conventional round port tube found on many speakers, Klipsch uses a Tractrix horn-shaped opening for smoother, more efficient airflow in and out of the cabinet. The resulting decrease in air turbulence makes for cleaner, more powerful bass with reduced port noise and low-frequency distortion.
