Description

Legendary Vintage Klipsch 3-Way Speakers Custom finished in Solid Cherry Veneer.

The Heresy has for decades garnered a storied reputation among high-end audio enthusiasts. Made by hand in the US, this is a true high fidelity loudspeaker system.

The history of the Klipsch Heresy is rich. It was originally introduced in ’57 as a center channel speaker to go between two Klipschorns in larger rooms. When Paul Klipsch came up with the idea and the design, people told him he couldn’t do it, that it was acoustic heresy. “The hell I can’t,” he said, “and that’s exactly what I’m going to call it.” The resulting Heresy was a 3-way, acoustic suspension (sealed) design with a horn tweeter, horn midrange, and a 12” accordion surround woofer.

The Heresy’s will bring out things in recordings you just won’t hear with other speakers. There are details, subtleties, and elements that they bring out in the soundstage that are unique to only them. Speaking of soundstage, when properly placed, they have amazing imaging that is very tough to duplicate.

The voice (flavor) of the Heresy is absolutely a very forward one. There is no mistaking the horn-loaded sound. Yet, the acoustic suspension (some have argued infinite baffle) design does make the bass a bit more subtle and tight than many other Klipsch offerings.

From Klipsch:

“Quality sound system for theaters, homes, and nightclubs; monitor for recording and broadcast studios; or other professional or serious amateur use where faithful reproduction is demanded.

The Klipsch Heresy Loudspeaker is a high-efficiency, low-distortion system covering a wide range of frequencies with an unusually smooth response. Bass range extends solidly from 50 Hz, usable to 45.

This loudspeaker affords the same smoothness of response as the Klipschorn, but the bass cutoff is approximately 20 Hz higher. Horn-loaded throughout its treble spectrum, it maintains low diaphragm amplitudes and velocities necessary for low modulation distortion. The resulting clarity, a feature of all our speakers, even at the volume levels required for auditorium use, is typical of this highest level of quality.”

Pricing: As with many classic vintage speakers, the pricing for the Heresy’s is all-over the map. One reviewer mentioned a garage-sale find at just $15 (wow!) High water mark that we could find is a beautiful fully customized pair in high gloss orange (very cool) at $5K USD (about $6770 Cnd). Our pair has been beautifully refinished in solid cherry veneer. Grills have been freshly re-clothed, and we special ordered replica Klipsch “Laser” badges to complete the look. We made the conscious decision to leave the back panels original so as to not cover the original labels. They are not sequentially numbered, but they are a beautiful pair, and they sound fantastic, with all drivers doing their jobs perfectly. They also look fantastic on our Radique Audio Hand-Crafted 14″ Cherry Finished Speakers stands (sold separately).

Klipsch began in Hope, Arkansas, in 1946, when Paul W. Klipsch started building his corner-horn Klipschorn, and its Heritage speakers are still built by hand in Hope.

The Klipsch story, 1946 to today

Paul W. Klipsch was posted to Hope, Arkansas, in 1941 as an Army officer. He patented his corner-horn design in the mid-1940s and founded Klipsch in Hope in 1946; Klipsch says its first speaker was built by hand there that year, with the horn made in a tin shed. He hired his first employee in 1948.

The Heritage line. The Klipschorn of 1946 was followed by the Heresy (1957), designed as a centre speaker to sit between a pair of Klipschorns, the Cornwall (1959), the La Scala (1963) and the Forte (1985).

A new generation. Fred Klipsch bought the company from Paul Klipsch in 1989, and headquarters later moved to Indianapolis. Paul Klipsch died in 2002 at 98. The Reference Series arrived in 1999.

A Canadian connection. In 2006 Klipsch bought Audio Products International of Toronto, with its Energy and Mirage brands. Audiovox, later VOXX, bought Klipsch in 2011, and Gentex bought VOXX in 2025.

Which Klipsch is which?

Heritage: the Klipschorn, Heresy, Cornwall, La Scala and Forte, built to order by hand in Hope. Drivers change between generations, so identify the version.

KG series (mid-1980s to early 1990s): lower-priced horn-tweeter floorstanders such as the KG 4 (1985 to 1992) and KG 5.5.

Reference (1999 onward): horn-tweeter towers, bookshelf speakers and centres, from the RB-5 and RF-7 to the later RF, RB and RC models.

Synergy (late 1990s and 2000s): such as the KSF 8.5 and the SF-1.

Subwoofers: powered models such as the RPW-10.

Buying used Klipsch: what to check

Horn diaphragms. The compression drivers in older Klipsch speakers age; owners report tired midrange diaphragms on Heritage models and raspy tweeters on some KG pairs. Listen to each horn on its own at a moderate level.

Reference tweeters. A crackling tweeter can be a loose connection, and owners say these tweeters can fail if played very loud.

Crossovers and passive radiators. Many Heritage and KG owners recap their crossovers, and KG passive radiators can have cracked surrounds.

Modifications. Aftermarket diaphragms and crossovers are common upgrades on Heritage and KG models. Ask what has been changed.

Where it was made. Heritage models are built in Hope. Check the label before calling any other Klipsch "made in USA".
