(March 25, 2025) Klipsch has introduced updated versions of two of its most storied loudspeakers—the Klipschorn and La Scala—while also launching a new Heritage Active Crossover that can be paired with either model. The updates retain the legacy designs that date back to the 1940s and 60s, respectively, but incorporate modernized components and signal processing capabilities intended to refine time alignment, tonal balance, and overall system flexibility.
The new Klipschorn AK7 and La Scala AL6 feature a redesigned Tractrix midrange horn (K-406M) and a 3" KT-1133-HP midrange compression driver—a full inch larger than previous models. These changes increase output and improve phase coherence. Both models also use Klipsch’s patented Mumps technology, which helps maintain consistent frequency response to the edges of the horn. The result is more even dispersion and better imaging. High frequencies are handled by the K-771 compression driver, now paired with an extended phase plug designed to reduce cancellations and equalize wavefronts.
Bass response sees notable differentiation between the models. The Klipschorn maintains its iconic fully horn-loaded 15" woofer (K-33-E) design, with a frequency response extending as low as 34Hz. Meanwhile, the La Scala AL6 incorporates a newly vented 12" folded-horn woofer (K-281), marking a significant departure from earlier sealed designs. This change allows the La Scala to produce deeper and fuller bass while maintaining efficiency and clarity.
To support the new drivers and crossover configurations, both models include redesigned input/output panels with provisions for both passive and active setups. That flexibility supports Klipsch's newly released Heritage Active Crossover—a dedicated DSP-based unit explicitly built for the Klipschorn AK7 and La Scala AL6. Developed by Klipsch VP of Technology and Innovation Matt Spitznagle and tuned by longtime engineer Roy Delgado, the crossover uses advanced signal processing to align time and phase between drivers and includes user-adjustable high- and low-frequency gain.
"We are always looking to improve performance even on these iconic designs. You can’t stop a creative mind, and as PWK used to say, 'You can’t time creativity,'" said Roy “Chief Bonehead” Delgado, Jr., Klipsch principal engineer. He added, "While we are thrilled with the performance of the passive crossover, the Heritage Active Crossover unlocks performance enhancements that are simply unattainable with a passive design."
The Heritage Active Crossover enclosure is constructed with veneered MDF, a steel front panel, and measures 17" wide by 14.125" deep. It offers balanced and unbalanced inputs and outputs, supports auto power switching, and provides a frequency response of 10Hz to 45kHz within ±0.5 dB. THD performance is rated at 0.001% (20Hz-20kHz @ 1Vrms), with 115dB of dynamic range.
Both loudspeakers are available in American Walnut, Black Ash, and a new American Auburn wood veneer finish, with book-matched panels across all cabinets. Pricing is set at $17,998/pair for the Klipschorn AK7 and $14,998/pair for the La Scala AL6. The Heritage Active Crossover is available separately at $3,499 per unit. All products are built and assembled in Hope, Arkansas.
