Klipsch La Scala AL6 Horn-Loaded Loudspeaker (Pair)

Klipsch La Scala AL6 Loudspeakers

The Klipsch La Scala AL6 loudspeakers continue the legacy of the original 1963 design, offering high-efficiency sound reproduction through a three-way, fully horn-loaded system. Part of the Klipsch Heritage series, the AL6 incorporates updates to drivers, horns, and bass enclosure design compared to previous iterations.

Key Features

• Three-way system utilizing horn-loading for high, mid, and low frequencies.
• High sensitivity (103dB @ 2.83V/1m) suitable for use with a wide range of amplifiers.
• Updated drivers and horns including a new Tractrix® midrange horn.
• New horn-loaded vented bass enclosure design.
• Inputs compatible with standard passive operation or optional external active crossover systems.
• Hand-built in Hope, Arkansas, USA.

Driver and Horn Technology

• High Frequency: K-771 1” compression driver fitted with a patented extended phase plug, coupled to a K-792 exponential horn for wide dispersion.
• Mid Frequency: New K-1133-HP 3” compression driver (larger than previous models) coupled to a new K-406M modified Tractrix® horn featuring Mumps technology for smooth coverage.
• Low Frequency: New K-281 12” fiber-composite cone woofer housed in a patented horn-loaded vented system, designed to integrate horn efficiency with bass-reflex extension.

FAQ

• How do the La Scala AL6 loudspeakers compare to the earlier AL5?

  The La Scala AL6 features several updates: a new K-1133-HP 3" midrange driver (vs. 2" K-55-X), a new K-406M Tractrix midrange horn (vs. K-401 exponential), an extended phase plug on the K-771 tweeter, and a new horn-loaded vented bass system with a K-281 12" woofer (vs. the AL5's fully horn-loaded K-33-E 15" woofer). It also has a redesigned input panel supporting optional active crossovers.

• What is the optional Heritage Active Crossover?

  It's an optional, external DSP (Digital Signal Processing) unit, custom-tuned for the La Scala AL6 loudspeakers (and Klipschorn AK7) based on technology from the Klipsch Jubilee. Connecting to the speaker's active inputs, it uses advanced signal processing to precisely manage crossover points, deliver synchronized time/phase alignment, and provide balanced EQ for a true-to-source response. It goes beyond the standard passive crossover's capabilities and includes user-adjustable high and low-frequency gain controls for system fine-tuning.

• Is the La Scala AL6 suitable for home theater use?

  Yes, its high efficiency, wide dynamic range, and ability to produce high sound pressure levels make it suitable for demanding home theater applications as main front speakers.

• What finishes are available for the AL6?

  The AL6 is offered in American Walnut, Black Ash, and American Auburn book-matched wood veneers.

• Can these speakers be positioned in any room without affecting sound quality?

  The horn-loaded design provides controlled directivity, which can help manage room interactions compared to wider dispersion speakers. However, like all speakers, room placement (especially proximity to walls and corners) will still influence the final sound quality, particularly in the bass frequencies. Experimentation with positioning is recommended for optimal results.

The Klipsch La Scala AL6 delivers high-efficiency, dynamic sound reproduction based on decades of horn-loading expertise, incorporating updated technology for modern listeners.
