The One and Only Klipsch Klipschorn Floor-Standing Speakers: AK7 Iteration of One of the Most Renowned Models Ever Devised Is Loaded with Innovations, Plays with Exceptionally Lively Detail, Emotion, and Energy 

No floor-standing speaker in audio history claims a richer heritage than the Klipsch Klipschorn. And few, if any, have proven as influential. In continuous production for more than 75 years – a longevity record approached by no other model – this three-way fully horn-loaded design stands as a testament to pioneering engineering, extraordinary vision, and flawless execution. It is an indisputable legend – a classic that never goes out of style. Particularly in its latest iteration, Klipschorn AK7.

Handcrafted in the U.S.A. and capable of extreme output levels, the three-way Klipschorn AK7 remains true to the original goal of reproducing the power, scope, detail, and emotion of live performances in listeners' homes. That the fundamentals of the speaker are still the same as they were at its inception further attest to the brilliance of this watershed invention. As the latest version of the model named one of "The 12 Most Significant Loudspeakers of All Time" by The Absolute Sound, Klipschorn AK7 boasts incredibly high sensitivity (103dB), smooth frequency response, ultra-low distortion, controlled directivity, and profound dynamics.

Engineered to seamlessly work with the optional Klipsch Heritage Active Crossover to achieve standard-setting balance, AK7 comes with an upgraded internal crossover plus a redeveloped back-panel I/O panel that includes both passive and active inputs — and a passive output — making switching between setups a cinch. Coupled to a new K-406M Tractrix midrange horn with Mumps technology, the brand-new three-inch K-1133-HP midrange compression driver supplies incredible sound pressure to the horn’s throat for voluptuous levels of volume and energy. In short, this invigorating combination means AK7 provides more coverage, presence, consistency, and precision than any prior iteration of Klipschorn. 

To handle the high frequencies and spoil you with breathtaking clarity, a K-771 compression driver with a patented extended phase plug is mated to a K-792 horn to effectively prevent cancellations and equalize wavelengths for clean dispersion. For probing depth and rich, impactful bass, AK7 turns to a K-33-E 15-inch woofer in a fully enclosed horn-loaded system that eliminates any need for each speaker to be placed tightly against the corner of a room. As long as it is close to a corner, you'll realize the dramatic ability of the horn. And yes, the speaker's physics still utilize the walls and floor as low-frequency extensions of its patented woofer – one of the most revolutionary inventions in high-end history.

Every AK7 driver is further optimized for one of three individual pass-band arrangements that permits this bespoke speaker to be exponentially more efficient than other conventional loudspeakers. Higher efficiency means greater acoustic power generated with considerably less effort from the loudspeaker's diaphragm — a far less distortion. Let's just say you'll likely never need a subwoofer or doubt what a tube amplifier can do ever again.

Weighing 260 pounds a piece, and measuring 53.25 inches tall, 31.5 inches wide, and 28.125 inches deep, AK7 amounts to far more than a loudspeaker: It is a piece of your decor and a conversation-starting artwork. It literally shouts how much you value high-quality music playback and, as time has shown, will likely outlast any trend that comes along during the next seven decades. 

To ensure every AK7 looks as it great as it sounds, each unit comes with book-matched wood veneers that lend to flawless visual consistency and timeless appeal. A riser base with a cable-management system, bi-amp inputs and five-way binding posts crown a speaker that is like none other.

If you have the proper room and the space, we highly urge you to experience unprecedented audio history in your own home. Klipsch's 10-year warranty and the testimony of more than seven decades of listeners give you as much security in your decision as you'll ever need.

"The bass horn design has never been improved – it was perfect from day one."
—The Absolute Sound, The 12 Most Significant Loudspeakers of All Time

"Nowadays speakers with horn-loaded woofers are extremely rare, but – trust me on this – nothing pressurizes a room like a pair of K-Horns with 15-inch bass drivers."
—Steve Guttenberg, Sound & Vision

"No one with a taste for realistic playback, and especially no one with a taste for low-power amps and high-sensitivity speakers, should miss a chance to hear these."
—Art Dudley, Stereophile

Three-Way, Horn-Loaded Efficiency 
Klipschorn's three-way, horn-loaded system delivers exceptional efficiency. For AK7, each driver is coupled to a precisely measured horn and optimized for one of three pass-bands. This design generates greater acoustic power with less wattage, producing crystal clear sound with minimal distortion across the frequency spectrum.

Get a Big Boost with the Heritage Active Crossover 
AK7 was meticulously engineered with an optional Heritage Active Crossover in mind, which has been tuned specifically for Klipschorn speakers by master acoustician and PWK protégé Roy Delgado. Trickle-down technology from Klipsch's heralded Jubilee floorstanding speakers, the Heritage Active Crossover aligns time and phase while boosting frequencies and balancing EQ for a flat, color-free response.

Extended Phase Plug for Highs
The K-771 compression driver is paired with a new, patented, extended phase plug to prevent cancellations and equalize wavelengths for cleaner dispersion. That means you get more coverage and clarity.

Three-Inch Compression Driver Delivers Power
The new, midrange K-1133-HP compression driver adds a full inch to the drivers on previous AK6 models. The larger compression area increases sound pressure to the horn’s throat for more voluptuous volume.

Spread the Soundstage with Mumps and Tractrix
AK7 gets the Tractrix treatment. Compared to what was in the AK6, the new K-406M patented Tractrix midrange horn features a shorter, two-inch throat for unparalleled presence and precision. Mumps technology improves coverage, adding small contours to help maintain frequency response to the horn’s edge.

Boom the Bass
The Klipschorn’s fully enclosed low-frequency horn, paired with the powerful K-33-E 15-inch woofer, delivers deep, rich bass with remarkable clarity and impact. Its innovative folded horn design increases bass extension and efficiency.
