Henley Audio has announced the UK introduction of two new Klipsch® Heritage Series speakers. First unveiled by Klipsch in late-2019, the latest-generation Heresy IV and Cornwall IV designs are now available in the UK through Henley Audio’s network of Klipsch Heritage stockists.

Klipsch Heritage speakers are handcrafted in the USA, based on designs originally drawn by company founder Paul W. Klipsch. With these latest generation announcements, the Heresy IV and Cornwall IV successfully advance on their historical legacy for sound, while still being relevant for modern applications and environments.

Klipsch Heresy IV

First introduced in 1957, the Heresy is a three-way loudspeaker design that started out as a compact centre channel to accompany the Klipschorn® in three-speaker stereo arrays. The Heresy IV (£3,500.00 SRP) is an entirely re-voiced and re-worked latest generation design of this iconic speaker.

When Paul W. Klipsch was developing a small speaker for centre channel use, an acquaintance declared that he couldn’t possibly introduce it to the public because it was in direct violation of the corner horn principles and amounted to acoustic heresy. “The hell I can’t,” Mr Klipsch said. “And that’s exactly what I’m going to call it”! Since then, the Heresy has been one of Klipsch’s most popular speaker models and now marks the entry point to the flagship Heritage Series range.

Acoustically, the Heresy IV benefits from a K-107-TI titanium diaphragm high frequency driver, with an all new wide-dispersion phase plug, above a new K-702 midrange compression driver, with a polyimide diaphragm mated to a K-704 Tractrix® horn. For the bass, a K-28-E 12” woofer does the job. Elsewhere inside, there is an all-new high-fidelity crossover network, based on the Klipschorn’s three way steep-slope design, for truer to life sound, best-in-class efficiency, and comfortable power handling. Internal cabling is supplied by Audioquest.

For the first time in its long legacy, the Heresy now also features a rear port – improving low-frequency extension by almost 10Hz against the previous version. Utilising Tractrix  geometry, the Heresy IV ports allow for fast  and efficient air transfer.

The Heresy IV has also benefited from a series of cosmetic improvements. With cabinetry still handcrafted in Hope, Arkansas, each speaker pair has a book-matched wood veneer finish. The taller and narrower profile, compared to its predecessor, as well as the updated grille, also make the Heresy IV appear more elegant than before. The subtle matte black slant-riser base is removable for different installation options in any environment.

SRP £3,500.00

Available in American Walnut, Natural Cherry, Satin Black Ash and Distressed Oak finish.

Klipsch Cornwall IV

The Cornwall was introduced in 1959 to serve as a larger, full-range alternative to the Heresy® and  was so-named because you could conveniently position it either in a corner or against a wall. Utilising a three-way design with horn-loaded compression drivers for the midrange and treble, alongside a direct-radiating 15-inch woofer for the low frequencies, the Cornwall delivers a full-range response with a sensitivity approaching that of fully horn-loaded models.

As the “largest of the compact” Heritage speakers, the Cornwall IV (£6,500.00 SRP) offers the highest performance of any non-fully horn-loaded speaker Klipsch make. Only the Klipschorn and La Scala (with their horn-loaded, low-frequency designs) exceed the Cornwall in bass extension and output. But with the latest updates introduced in the Cornwall IV, this storied loudspeaker is ready to achieve even greater significance than its illustrious predecessors.

Inside, the Cornwall IV features a new mid-frequency driver and a new large format midrange horn with mumps technology for better response throughout the frequency band. Above the mid-range is Klipsch’s popular K-107-TI 1” tweeter and below is a K-33-E 15” Fibre-composite cone woofer for deep bass. Married together with a newly voiced cross-over network, featuring high-quality Audioquest cabling throughout. The Cornwall IV retains the front-port design of its predecessor, but the system has been improved with Klipsch’s Tractrix port technology. Utilising Tractrix geometry, the Cornwall IV can achieve fast and efficient air transfer.

The outside of the Cornwall IV is a change from its predecessors as well. It features a new logo design grille to match other Heritage products, and a new matte black riser to give a floating appearance.

Finished in one of three elegant book-matched wood veneers, each Cornwall IV cabinet is still made in the company’s factory in Hope, Arkansas.

SRP £6,500.00

Available in American Walnut, Natural Cherry and Satin Black Ash finish.
