Klipschorn AK7 Heritage Floorstanding Speakers

The loudspeaker that started it all. Since 1946, the Klipschorn has remained the benchmark for high-efficiency loudspeaker design. The new AK7 preserves Paul W. Klipsch's original vision while incorporating the most significant engineering improvements in decades.

The Speaker That Founded Klipsch

The Klipschorn was the very first loudspeaker designed by Paul W. Klipsch and remains the longest continuously produced loudspeaker in the world.

For more than 75 years, it has demonstrated that extraordinary efficiency, extremely low distortion, and effortless dynamics can reproduce music with a realism few conventional loudspeakers can match.

The AK7 continues that remarkable legacy while incorporating modern acoustic engineering inspired by the flagship Jubilee.

The Most Advanced Klipschorn Ever Built

Rather than simply updating cosmetic details, Klipsch substantially redesigned the AK7.

Major improvements include:

• New cinema-grade 3-inch compression midrange driver
• Patented Tractrix® midrange horn
• Mumps™ horn geometry
• New extended phase plug
• Redesigned rear input panel
• Optional Heritage Active DSP Crossover
• Improved passive crossover network

Together these upgrades deliver greater accuracy, wider dispersion, improved imaging, and even more effortless dynamics.

Fully Horn-Loaded Three-Way Architecture

Unlike traditional loudspeakers that use direct-radiating woofers, the Klipschorn horn-loads every driver.

Driver complement includes:

• 15-inch folded horn-loaded woofer
• 3-inch K-1133 compression midrange driver
• K-771 compression tweeter
• Dedicated horn for every frequency range

Benefits include:

• Extraordinary efficiency
• Extremely low distortion
• Exceptional transient response
• Massive dynamic capability
• Live-performance realism
• Very low amplifier requirements

Few loudspeakers reproduce music with the effortless scale of a fully horn-loaded system.

Legendary Folded Corner Horn Bass

The Klipschorn's defining feature remains its fully enclosed folded bass horn.

Rather than using a conventional bass-reflex cabinet, the speaker utilizes the room's corners as an extension of the horn itself.

Advantages include:

• Exceptional bass efficiency
• Deep, effortless low frequencies
• Extremely low distortion
• Outstanding transient response
• Minimal power compression
• Incredible dynamic realism

Proper corner placement allows the Klipschorn to deliver bass performance unlike virtually any conventional loudspeaker.

New Cinema-Grade Midrange Driver

The AK7 introduces the new K-1133 compression driver.

Improvements include:

• Larger 3-inch diaphragm
• Greater acoustic output
• Improved efficiency
• Lower distortion
• Better vocal realism
• Increased dynamic headroom

Hand-built in Hope, Arkansas, the driver borrows technology developed for professional cinema loudspeakers.

New Tractrix® Horn with Mumps™ Technology

The redesigned K-406M Tractrix horn improves nearly every aspect of midrange reproduction.

Benefits include:

• Wider listening area
• More even frequency response
• Better imaging
• Improved tonal consistency
• Enhanced vocal presence
• Reduced horn coloration

Mumps technology maintains frequency response across the horn mouth for more consistent performance throughout the listening room.

Extended Phase Plug

The K-771 tweeter now incorporates Klipsch's patented extended phase plug.

Advantages include:

• Improved high-frequency dispersion
• Greater detail retrieval
• Better imaging precision
• Reduced cancellations
• More consistent off-axis performance
• Enhanced transparency

This refinement produces cleaner and more natural treble than previous generations.

Optional Heritage Active DSP Crossover

One of the AK7's most important upgrades is compatibility with the optional Heritage Active DSP Crossover.

Derived directly from the flagship Jubilee, the DSP crossover provides:

• Time alignment
• Phase correction
• Precision equalization
• Improved driver integration
• Flatter frequency response
• Greater overall transparency

Owners can begin with the passive crossover and later upgrade to active operation using the redesigned rear connection panel.

Extraordinary Efficiency

With sensitivity exceeding 105 dB, the Klipschorn AK7 ranks among the world's most efficient home loudspeakers.

Benefits include:

• Huge dynamic range
• Minimal amplifier requirements
• Extremely low distortion
• Concert-level output
• Effortless musical presentation
• Outstanding realism

Even a few watts of clean power can produce room-filling sound.

Handcrafted in Hope, Arkansas

Every Klipschorn AK7 is individually handcrafted in Hope, Arkansas.

Features include:

• Book-matched real wood veneers
• Hand-selected cabinet materials
• Precision assembly
• Heritage craftsmanship
• American Walnut
• American Auburn
• Black Ash finishes

Each pair is carefully matched for appearance and acoustic consistency.

Amplifier Matching

The Klipschorn AK7 pairs beautifully with both tube and solid-state amplifiers.

Because of its exceptional efficiency, even single-ended tube amplifiers with modest power can produce remarkable results.

Proper Room Placement

Unlike most loudspeakers, the Klipschorn is specifically engineered to use room corners as part of its bass horn.

For optimum performance:

• Install tightly into room corners
• Use symmetrical placement
• Avoid open side walls
• Maintain similar boundary conditions on both speakers
• Position the listening seat well outside the near field

Proper corner loading is essential for achieving the Klipschorn's legendary bass performance.

Compared to the Previous AK6

The AK7 introduces numerous improvements over the AK6:

• Larger cinema-grade midrange driver
• New Tractrix® horn geometry
• Mumps™ technology
• Extended phase plug
• Optional Heritage Active DSP compatibility
• Improved dispersion
• More accurate tonal balance

These updates make the AK7 the most refined Klipschorn ever produced.

Sound Quality

Listeners consistently describe the Klipschorn AK7 as delivering:

• Unlimited dynamics
• Effortless realism
• Massive soundstage
• Lightning-fast transient response
• Exceptional vocal presence
• Live-performance energy

Its ability to reproduce music with virtually unrestricted dynamic capability has made the Klipschorn an icon for generations of audiophiles.

The Original High-Efficiency Reference

More than seventy-five years after its introduction, the Klipschorn continues to define what is possible in horn-loaded loudspeaker design.

The AK7 builds upon Paul W. Klipsch's original vision with meaningful engineering improvements, advanced driver technology, optional Heritage Active DSP integration, and handcrafted American construction.

For music lovers seeking one of the most legendary loudspeakers ever created, the Klipschorn AK7 remains an enduring reference.
