Klipsch La Scala

The Klipsch La Scala speakers have an exceptionally high sensitivity rating, typically rated at approximately 104 dB at 1 watt/1 meter, which is among the highest of any consumer loudspeaker. This extraordinary efficiency means they can reach very high volume levels driven by amplifiers rated at just a few watts.

The La Scala uses horn-loaded compression drivers for the high and mid frequencies, which acoustically amplify the signal far more efficiently than conventional direct-radiating drivers. Paul W. Klipsch designed this approach in the 1960s specifically to maximize acoustic output from the low-powered tube amplifiers that were standard at the time.

While the La Scala produces powerful dynamics and articulate mid-bass, its folded-horn bass cabinet design causes the low-frequency response to roll off below approximately 50 Hz. Many owners add a subwoofer for full-range music or home theater use, though for most music genres the La Scala's bass extension is considered satisfying on its own.

The modern La Scala AL5, produced as part of Klipsch's Heritage series, uses updated crossover networks and a refined tweeter diaphragm while maintaining the original horn-loaded architecture and cabinet dimensions. Vintage La Scala models from the 1960s and 1970s remain popular among collectors but may require driver refoaming or crossover capacitor replacement to perform at their best.
