Born from the American audio tradition, the Cornwall IV American Club Edition represents the culmination of six decades of Klipsch acoustic excellence. This special edition, limited to just 100 pairs worldwide, features an exclusive Dark Cherry finish that enhances its timeless design. Combining modern technologies with proven acoustic philosophy, this high-efficiency three-way speaker carries on the legacy of Paul W. Klipsch while delivering remarkably precise sound reproduction. Impressive in both size and performance, it is an audiophile investment designed to be passed down through generations.
First introduced in 1959, the Cornwall speaker was originally designed as an alternative to the Heresy, serving as a center channel between two Klipschorns. After production was temporarily halted in 1990, a wave of protests from enthusiasts led to its triumphant return to the Klipsch catalog.
The American Club Edition celebrates this heritage with an ultra-limited series of 100 pairs in a unique Dark Cherry finish, giving the speakers an exceptional visual presence. This collector’s status is matched by the acoustic performance that has made this iconic Heritage range model so renowned.
The design of the Cornwall IV retains the visual identity that has made it successful since its origins, with a few contemporary refinements such as the new black plinth, which creates a floating effect for the front panel. Its redesigned logo harmonizes with the rest of the current Heritage range, while its dual binding posts, compatible with bi-amping, are set on an elegant brushed metal panel.
True to Klipsch’s philosophy, the Cornwall IV American Club is based on a highly efficient three-way design. Its architecture combines a 38 cm (K-33-E) direct-radiating woofer for low frequencies with two horn-loaded compression drivers for the midrange and treble.
The K-702 midrange driver uses a 4.45 cm polyimide diaphragm for exceptional detail and dynamic reproduction. It is paired with a modified Tractrix horn featuring patented “Mumps” technology, which optimizes the polar dispersion of midrange frequencies, ensuring remarkable sonic coherence throughout the listening area.
For the treble, the K-107-TI compression driver with a 2.54 cm titanium diaphragm delivers exemplary precision and extension, without the aggressiveness that characterized some older Klipsch models.
The passive crossover has been completely redesigned with a steep-slope topology inspired by the legendary Klipschorn and La Scala, using high-end components to minimize electrical degradation and preserve signal integrity.
The Cornwall IV marks a significant step forward from its predecessor with several major improvements. The new K-702 midrange compression driver, paired with a redesigned horn, offers increased clarity and more detailed reproduction of the midrange frequencies, where most musical information resides.
The front-firing Tractrix ports have been optimized to improve air transfer efficiency, reducing port noise while increasing bass pressure and depth. This design delivers deeper and better-defined bass than the previous generation.
The internal wiring has been completely revised to maintain signal integrity, while the new binding posts make connections easier and allow for bi-wiring or bi-amping.
These improvements result in a faster, more expressive, and less directional listening experience than the Cornwall III, with a more natural and engaging sound presentation.
The Cornwall IV American Club stands out for its ability to deliver a life-sized soundstage with striking dynamics. Its extraordinary efficiency of 102 dB (2.83V/1m) allows it to reach impressive sound levels with very little power, even when driven by amplifiers of just a few watts.
Listeners often report discovering musical details they had never noticed before in their familiar recordings—subtle bass lines, keyboard nuances, or complex rhythms that were previously masked. This ability to reveal the texture and structure of recordings transforms the listening experience into a true musical exploration.
Contrary to common misconceptions about horn speakers, the Cornwall IV does not exhibit tonal coloration or harshness. After a break-in period of about 400 hours, it offers a natural and refined reproduction of acoustic instruments and voices. The accuracy of timbres and tonal coherence allows it to excel with symphonic music as well as jazz, rock, or electronic genres.
The bass performance is particularly remarkable—despite the large 38 cm woofer, the bass is fast, articulate, and free from artificial resonance, effectively reaching down to 34 Hz. This speed preserves the clarity of the midrange without masking or frequency overlap.
Although its imposing size (96.5 cm high, 64.3 cm wide, 39.4 cm deep) requires substantial space, the Cornwall IV is more flexible in placement than it might appear. Originally designed as a corner speaker (hence the name “Corn-wall”), it can be positioned against a wall without compromising its acoustic performance.
Its exceptional efficiency allows it to pair with amplifiers of any power. Low-power tube amp enthusiasts will particularly appreciate this feature, as it enables comfortable listening levels with just a few watts. The nominal 8-ohm impedance also facilitates compatibility.
For optimal integration into a listening room, it is recommended to maintain sufficient distance from the listening position. The Cornwall IV projects a powerful and expansive sound that benefits from some space—unlike speakers designed for nearfield listening.
Demanding users can take advantage of the dual binding posts for bi-wiring or bi-amping, further optimizing separation between frequency ranges.
The American Club Edition is an ultra-limited series of 100 pairs worldwide, featuring an exclusive Dark Cherry finish not available on standard models. The technical specifications and acoustic performance remain identical, but the collector’s status of this special edition makes it a particularly sought-after investment for brand enthusiasts.
With their large dimensions and expansive sound character, the Cornwall IV is ideally suited for medium to large rooms. In a small space, their physical and acoustic presence may be overwhelming. For more modest spaces, other models in the Heritage range, such as the Heresy IV, offer a more appropriate alternative while retaining the Klipsch sound signature.
Thanks to their exceptional efficiency of 102 dB, the Cornwall IV can reach comfortable sound levels with just 2 to 20 watts. They are particularly well-suited to low-power tube amplifiers. The maximum admissible power of 100W RMS (400W peak) also allows for the use of more powerful amplifiers, though this is rarely necessary for home listening.

Very happy with my purchase, pairs perfectly with my Line Magnetic LM-216IA. I’m rediscovering my music with an incredible amount of detail

In the same vein as the klf30
Very good reproduction with a tube amplifier both at low power 2 to 3 W and at 6-7 W
Then the reproduction will depend on the amplifier and the listening room
After the klf30, no disappointment with the Cornwall

Slight cabinet and midrange horn resonance. Listening experience radically different from the RF-7s they replace: remarkable tonal balance and treble that extends smoothly.
On first listens, there’s a strong bass resonance that makes you want to send everything back, but it disappears with break‑in. Full, expansive bass, very different from the ultra-tight upper bass of the La Scala and RF-7.
On paper, the crossover frequency is too high for the woofer and too low for the mid compression driver. In practice, the bass driver has a bit of trouble reproducing complex symphonic passages without intermodulation. On the other hand, the whole setup excels on live rock or jazz, or on tracks with soloists.
The 15" woofer moves very little yet shifts large volumes of air. The result is very low distortion, even at high volume.
Very high efficiency: you can hear tube hum. On the scope, I very rarely reach 250 mW. At that level, many class A/B amps are actually running in class A, and single-ended tube amps operate with “reasonable” distortion levels. Under these conditions, in fact, many amps with undersized power supplies and output transformers become usable and musical.
With an SMSL SU9 + DIY tube buffer + NAD C298: ultra-realistic, ultra-dynamic, and musical listening. With an AN 300B kit, very pleasant but you can hear the bandwidth limitations of the transformers. With an Aleph 3 clone, superb sound. With a Yaqin VK2100, a big surprise with a pleasant sound, far less colored than on 92 dB Triangle speakers. It really makes you want to try a 2A3 or a First Watt F4. Choose an amp with low gain, or a 32‑bit digital preamp, otherwise you’ll end up with the volume at minimum. As for soundstage, with the 15" drivers there’s a sense of a sort of sound wall, not unpleasant. Would deserve a DSP for time alignment between bass and midrange. All in all, a very fine achievement by the engineers at Klipsch. And a VERY good pair of speakers for those who listen to jazz or rock. Not disappointed with the purchase.
