Klipsch Cornwall Vs. Heresy

The Klipsch Heresy distinguishes among other speakers available for purchase for one particular reason: value. Speaking of audio, the Heresy just has fantastic audio. 

However, Klipsch Cornwall speakers are powerful in sound. They offer a huge, realistic sound staging and are among the few great speakers users will ever hear.

Klipsch Cornwall IV

The Klipsch Cornwall IV speakers are enormous, gorgeous, and prohibitively expensive. The Cornwall IVs, however, would have been the only piece in town if you were looking for excellent craftsmanship, epic design, and distinctive sound. 

They may be driven by almost any combined amp, stereo receiver, signal conditioning, tube amplifier, or AVR on the marketplace and should be utilized in bigger rooms for optimum driver compatibility.

However, certain upstream equipment is more effective with the Cornwalls than others are. 

The most recent model of Klipsch’s 15-inch, direct radiating, and multiple Heritage series is the Cornwall IV.

There has always been a love/hate relationship between the Klipsch Cornwall and the new Cornwall IV, which features a new intermediate driver, extra horns, firmware upgrades, a redesigned HF phase plug, as well a new price. 

People adored them but complained about the bass extension and the woofer-to-midrange horn transition (the bass was almost deep enough to run without a subwoofer but was not quite there).


Before the Cornwall IV can be fully run, it will take around 400 hours. From a distance, it sounds fresh, vibrant, and lively but also a little ferocious and practically immediate.

As the loudspeaker continues, the sound becomes more polished and wide, appearing forward and relaxed. 

The middle compression driver’s architecture, with its ‘Mumps’ form of the Tractrix horn, is largely responsible for the fineness of the Cornwall IV. The result is clear, open, natural music free of noise and undesirable coloration. 

Speakers with horn-loaded middle and upper drivers, like the Cornwall IV, are aggressive.

They sound much more palatable after some distance. Yes, you may sit a short distance away, but the effects could be a little overwhelming if you play loud music.

The Cornwall IV, however, keeps its balance and clarity even when played loudly. Many factors, primarily horn loading and the usage of steep-slope connectors, cause this.

Shallow roll-offs cause drive units to overlap, which prevents dynamic separation and causes small midrange frequencies.

Bass Performance

The bass performance of the Cornwall IV is tight, shockingly deep, and boom-free. It has a quick and light tone that does not distort the middle and is good up to around 35Hz roughly.

The Cornwall IV has become really swift and expressive while we are on the subject. 

With big, lively changes in the piece of music that the other loudspeakers smooth over, it will amaze and surprise listeners. However, it extends beyond only the piano, percussion, and drums.

Individuals may hear a variety of dynamic intonations that produce music that is extra engaging when just listening.

Klipsch Cornwall IV Vs. Heresy IV

The Heresy becomes a three-way loudspeaker as a small center channel to go with the Klipsch throughout three-speaker stereoscopic arrays.

The current generation version of this speaker, the Heresy IV, has been completely re-voiced and reworked.

The Cornwall was developed to compete with the Heresy as a bigger, full-range option and was so named since you could put it either against a wall or in a corner.

The Cornwall IV uses a three-way setup with horn-loaded compression speakers for the middle range and high in addition to a direct-radiating 381mm speaker for the low-frequency range.

It also comes from new drivers and a new large-size medium-range trumpet using mumps innovation.

Design and setup

The Heresy IV employs a redesigned K-702 midrange compression producer with a polyimide diaphragm coupled to a K-704 Tractrix horn atop a new K-107-TI titanium diaphragm ultrasonic speaker with a new wide-dispersion period plug. 

There is a K-28-E 305mm subwoofer for the bass. A new crossover system is also included inside, which is based on the three-way steep-slope architecture of the Klipschorn. Audioquest provides internal cabling.

In comparison to Klipsch Cornwall’s, K-107-TI 25mm tweeter sits above the midrange, while the K-33-E 381mm fiber-composite cone woofer is located below. It has Audioquest wiring throughout and has a freshly voiced crossover network linked to it. 

The Cornwall IV has the front-port layout of its predecessor, but Klipsch’s Tractrix port technology has enhanced the system.

There is now a backport on the Heresy. In Hope, Arkansas, cabinetry continues to remain handmade. 

Each loudspeaker pair has a wood veneer finish that matches the books. With a revised grille and a taller and narrower profile than its predecessor, it comes in American Walnut, Natural Cherry, Satin Black Ash, and Distressed Oak finish.

Klipsch Cornwall III Vs. Heresy III

The Klipsch Heresy III speaker has a stunning aesthetic from top to bottom. The cabinet mimics the original’s timeless aesthetic without appearing too out of character in a contemporary setting.

The box is made of MDF with a premium Black Ash, Cherry, and Walnut laminate wood finish and was undoubtedly put together in the USA.

The speaker’s overall dimensions are 23.8 x 15.5 x 13.25 inches, with a little upward tilt. The speaker may be placed in various locations because of the tiny design’s size, which is just slightly bigger than a bookshelf.

The Sound Of Klipsch Cornwall III Vs. Heresy III

The Heresy III is small, but the sound is clearly not. The speaker produces powerful lows while keeping the middle and high end clear. 

Loudspeakers in this price range, making instruments farther up sound thin, typically crush the top end and are weak in comparison to the bottom end.

The Heresy IIIs are an exception to this. The speakers enable every frequency to pass through the whole range.

The Heresy III’s low-end extension was the most stunning aspect of the audio. The assertion that the range goes as low as 58Hz is valid.

There is virtually little roll-off down here, and all these loudspeakers punch even significantly below that range. The Heresy III’s speakers still have enough low-end power to satisfy even though they cannot match a subwoofer’s output.

The Heresy III functions just as well without music and has a stronger speaker than the Heresy II, which is a feature of Klipsch’s pro cinema series. Clear conversation and carefully imitated sound design are what is heard through in-home theatre installations. 

It is difficult to surpass the Heresy IIIs in this regard, given how frequently synthetic audio design is used in contemporary movies to establish the mood of the picture.

While comparing to Klipsch Cornwall III, when the rhythm section gets active, this allows you to hear the distinctions between the drumming, lower brass, and acoustic guitar parts of an orchestra. This is one advantage of the Klipsch Cornwall III. 

The interaction between the rhythmic patterns makes it possible to experience the composer’s intention better than any other speaker. Multiple intertwined melodies become apparent.

Acoustic bass and low synthesizer sounds are separate from the percussion in pop music and are very simple to follow.  

The “thumb on string” initial assault and the fading of the rhythm section are distinct and authentic in acoustic jazz. With the bass, there is a very slight amount of audible box resonance, but it is negligible and unnoticeable. 

On this model, Klipsch ought to have employed thicker (or better supported) cabinet walls.

However, since the resonance frequency goes inside the low 30s, there is no need for a subwoofer because this loudspeaker is generally simple to hear in the depths.


The Heresy IIIs provide a very authentic sound. However, the capacity to play loudly and clearly is one feature that is sometimes absent from a low-cost system. 

The Heresy IIIs are the complete opposite of the Magnepan MMGs, which have a smooth midrange performance but cannot truly rock, and can play industrial-strength rock and roll at respectable volumes while sacrificing a small amount of consistency.

With none of the pressure that can place when a less effective speaker is connected to a small power amplifier, these speakers can truly, rock.

With a 40 watts per channel tube amplification, playing 99 DB speakers is equivalent to having 1000 watts per channel available for 89 DB loudspeakers. The Heresy IIIs really pose a small hazard to your hearing since they play so loudly and clearly. 

The resolution of The Heresy III is maintained when playing softly. People might be astonished by how realistic acoustic and voice albums sound, especially at low volumes, even if they are not a metalhead. 

The Heresy IIIs are also equally linear and dynamic. The speakers maintained their composure when playing challenging music; they conveyed exquisite details at all volume levels.

Whereas the Cornwall III is a three-way system that uses direct-radiating 15-inch woofers for the low frequencies and horn-loaded compression speakers for the midrange and tweeter.

The Cornwall III offers a great balance of strong power output, minimal distortion, and wide frequency response. 

Use the same hardwood for the veneer panels; the grain of every pair of Classic Range speakers is matched. Each loudspeaker in the pair has been identified from the other thanks to meticulous cabinet matching. 

Through manufacturing, the speakers flow together without any gaps. Each completed item is examined, tagged with a unique product code, and tested before leaving the manufacturer to guarantee that the Heritage series speakers are a well-constructed pair.


The Heresy III’s phenomenal efficiency, as well as that of many other Klipsch speakers, is one of its most intriguing features. Even at relatively low power levels, in the 10W range, the Heresy III could still emit horrifying noises. The midrange and treble speakers with horn loads can achieve this efficiency. 

The Klipsch Heresy III can generate sound with an SPL greater than 100dB with very little power. These people can churn out the audio even with very little electricity because this is far better than many speakers on the market. 

Hence, 100 dB is the same as starting a chainsaw from one meter away, and it is only at 20 dB that hearing discomfort becomes an issue. The Heresy III can, needless to say, be rather noisy.

However, the Klipsch Cornwall III is the perfect speaker for people with less powerful amplifiers (or AV receivers). The speaker’s high 8-ohm impedance is fairly constant over the frequency range. 

The amplifier receives no challenging phase angles from the straightforward crossovers. Due to the great speaker sensitivity, just one or two watts would be adequate for 99% of the listening.

Among the most, “amplifier-friendly” speakers available are the Klipsch Cornwall III models.

Klipsch Cornwall Vs. Heresy Low Volume

The low-level recording, not the loud loudness, is what gives Klipsch its enchantment. They do not go out of business or crumble. Generally, Cornwall talks just as well as the Heresy does. The Cornwall is 38 Hz, whereas the Heresy is 50 Hz. 

It may not seem like a significant change, but it is. The Cornwall offers a moderate bassline that is not an overpowering thumper, similar to the Heresy.

Given that Cornwall can replicate at 30 Hz, we support this choice on “very little sound below 40 Hz,”. 

A normal piano and the electronic synthesizers used in many popular rock songs can produce low-frequency sounds up to 25 Hz. Note that the pipe organ operates at 20–25 Hz.

If people want to experience most of the music, they should not be restricted to a full-range speaker with a lower frequency cutoff of 50 to 60 Hz.

Frequently Asked Question

How good are Klipsch speakers?

For over fifty years, Klipsch has been a leader in the high-end speaker industry, and its products are renowned for their excellent sound, high quality, and dependability. Klipsch is a great option if you want to improve your audio system.

Is Klipsch a high-end brand?

They sound decent overall, of course. Most of their versions, including the low-end ones, are considered pretty good for their price, even if only their highest, most costly models may be labeled “high-end audio” or “audiophile quality.”

With ease and the least amount of distortion, Klipsch Cornwall can produce various sounds, including the most complicated ones. It must be good if a loudspeaker can reproduce music across its completely dynamic range. With perfect clarity, they replicate the sound.

A clean and clear sound may be heard. The Blatt is preserved in the copy of brass. Trombones and trumpets are nearby. Cornwalls are so compelling because of this. However, for the price, the Klipsch Heresy III has now become a monster of a speaker.
Although the small size and inexpensive cost would lead one to believe otherwise, these speakers deliver excellent sound in a classic style for a portion of the price of comparable speakers.

It would be tougher not to suggest the Heresy III than to suggest it to everyone regarding value, legacy, and sound quality. The Heresy III is a great choice if you are looking for a mid-priced loudspeaker that delivers high-priced music.
