Key Technological Advancements:

• Modified Tractrix Midrange Horns: Both the AK7 and AL6 feature the new, patented K-406M modified Tractrix midrange horn. This design incorporates a shorter 2" throat, improving time alignment by minimizing the distance between the driver's exit point and other drivers. This, combined with Klipsch's Mumps technology, ensures a wider, more consistent soundstage and a more natural, immersive listening experience.
• Updated Compression Drivers: The new 3" KT-1133-HP midrange compression driver, manufactured in Hope, Arkansas, represents a significant upgrade. Its larger compression area maximizes energy, allowing the driver to operate more efficiently and deliver greater sound pressure.
• Wide-Dispersion Extended Phase Plug: The K-771 high-frequency compression driver is paired with a patented wide-dispersion extended phase plug. This innovation minimizes cancellations and equalizes wavelengths, resulting in greater clarity and coverage across the high-frequency spectrum.
• La Scala's Vented Horn-Loaded Bass System: For the first time, the La Scala AL6 features a patented horn-loaded and vented system. This hybrid design combines the efficiency of a horn-loaded system with the extended output and lower distortion of a bass-reflex system. The K-281 12" woofer, housed in a new enclosure, delivers richer, more robust bass, regardless of room placement.
• Heritage Active Crossover (Optional): This cutting-edge external crossover, developed by Klipsch's VP of Technology and Innovation, Matt Spitznagle, and tuned by Roy Delgado, unlocks new levels of performance. Drawing inspiration from the flagship Jubilee, the active crossover provides superior time and phase alignment, balanced EQ, and true-to-source response. Users can fine-tune gain settings for the LF and HF sections to optimize their amplifier setup.
• Redesigned Input/Output Panel: The new I/O panel on both models features passive and active inputs, as well as a passive output, facilitating seamless integration with the Heritage Active Crossover.
• American Auburn Finish: Replacing the Natural Cherry finish, the new American Auburn finish adds a touch of modern elegance to these classic designs. The rich, deep hue complements the book-matched veneer process, ensuring a consistent and visually stunning appearance.

The Heritage Active Crossover: A Deep Dive into Sonic Precision:

The optional Heritage Active Crossover deserves special attention. This is not just an accessory; it's a transformative component that unlocks the full potential of the AK7 and AL6.

• DSP-Driven Precision: The active crossover utilizes a sophisticated DSP (Digital Signal Processing) network, enabling precise control over time and phase alignment.

• Enhanced Time and Phase Alignment: Unlike passive crossovers, which rely on fixed component values, the active crossover allows for dynamic adjustments, ensuring that all frequencies arrive at the listener's ears simultaneously. This results in a more coherent and immersive soundstage.
• Balanced EQ: The DSP-driven EQ allows for precise shaping of the frequency response, compensating for room acoustics and personal preferences.
• True-to-Source Response: The active crossover minimizes signal degradation, preserving the integrity of the original recording.
• Adjustable Gain Settings: Users can fine-tune the gain of the LF and HF sections to match the input sensitivities of different amplifiers, optimizing the overall system performance.
• Rack-Friendly Design: The elegant and compact design of the active crossover makes it easy to integrate into any audio setup.

Craftsmanship and Attention to Detail:

Klipsch's commitment to craftsmanship is evident in every aspect of the AK7 and AL6. Each speaker is meticulously handcrafted in Hope, Arkansas, using premium materials and time-honored techniques.

• Book-Matched Veneer: The cabinets are constructed using book-matched veneer, a process that creates a mirror image of the wood grain across two speakers. This ensures a consistent and visually stunning appearance.
• Premium Materials: Klipsch uses only the finest materials, including high-quality MDF and plywood, to ensure durability and optimal acoustic performance.
