Sound Character

The Klipsch Heresy is the definition of “live” sound. It does not politely step back; rather, it projects the music forward with thrilling immediacy and dynamic impact.

Because the Heresy utilizes a sealed enclosure (unlike many of its ported larger siblings), its 12-inch woofer delivers bass that is exceptionally tight, fast, and musical. The horn-loaded midrange is the star of the show, rendering vocals, brass, and electric guitars with a visceral realism and presence that conventional cone drivers simply cannot match. The horn tweeter adds a crisp, sparkling top end that captures the leading edge of cymbals and percussion perfectly.

This speaker thrives on dynamics. It is highly revealing, incredibly energetic, and rewards the listener with a front-row seat to the performance.

HQaudios Restoration & Testing Process

Drivers, Crossovers & Cabinets

The synergy between the high-efficiency horn drivers and the sealed 12-inch woofer is what gives the Heresy its unmistakable signature. A perfectly refreshed crossover network is absolutely vital to ensure this speaker sounds smooth and musical rather than harsh.

Because the acoustic integrity of these components dictates the final sound, they receive particular attention throughout HQaudios’ restoration process. Whenever possible, close-up photographs of the horn arrays, drivers, and wood grain are included, and additional photos or videos are available upon request.

Suggested Pairing

Because of their extreme sensitivity (often 96dB or higher), the Klipsch Heresy demands amplifier *quality* over *quantity*. They will reveal the true character of whatever amplifier you connect to them.

Basic Use Guide

To help maintain the long-term performance of your vintage horns, we recommend the following:

• Placement is key: The Heresy was designed to sit on the floor, ideally on angled riser bases, placed near a wall or in a corner to naturally reinforce its bass response.
• Do not use high-wattage amplifiers with high noise floors (hiss); due to the extreme sensitivity of the horns, any amplifier noise will be highly audible.
• Use high-quality, properly gauged speaker wire.
• Keep the cabinets away from direct sunlight and extreme humidity to protect the wood veneer.
• Contact us anytime if you need assistance with room placement, tube amplifier matching, or setup.
