The Klipsch Heritage

In 1946, a genius, madman, and maverick named Paul W. Klipsch revolutionized audio from a tiny tin shed in Hope, Arkansas. Armed with a patent for his corner horn design and an uncompromising attitude that earned him the unofficial company motto of "Bullshit!" - Paul Klipsch set out to bring the live concert experience into American living rooms. His goal wasn't just better sound; it was the truth of music itself.

From that humble tin shed to becoming one of America's most celebrated audio pioneers, Klipsch built a legacy on four acoustic principles that remain unchanged: high efficiency, low distortion, controlled directivity, and wide dynamic range. Today, 78 years later, Klipsch speakers are still hand-built in that same Hope, Arkansas facility - now a full-fledged factory where American craftsmen continue Paul's mission.

Product Excellence Defined

The Heresy IV represents acoustic heresy in the best possible way. Originally designed in 1957 as a center channel between Klipschorns, Paul Klipsch was told he couldn't possibly build a direct-radiating speaker - it violated his own corner horn principles! "The hell I can't," Klipsch said. "And that's exactly what I'm going to call it!" This rebellious speaker has been in continuous production ever since, evolving through four generations while maintaining its legendary sound.

Revolutionary K-702 Midrange Technology

• All-New Polyimide Diaphragm: Larger compression driver delivers exceptional clarity and dynamics
• K-704 Tractrix Horn Loading: Modified with Mumps technology for smoother response
• Extended Frequency Range: Covers 850Hz to 4.5kHz with minimal distortion
• Reduced Tweeter Stress: Lower 4.5kHz crossover point improves high-frequency performance
• Phase-Coherent Design: Seamless integration with woofer and tweeter
• Premium AudioQuest Internal Wiring: Type 4 Star-Quad Geometry for signal purity

Breakthrough Bass Performance

• First-Ever Rear Port Design: Tractrix geometry extends bass response by 10Hz
• 12" Fiber-Composite Woofer: High-efficiency design with powerful motor structure
• 48Hz Extension at -4dB: Unprecedented low-frequency performance for Heresy series
• Custom Port Flares: Reduces turbulence for cleaner, punchier bass
• Steep-Slope Network: Fourth-generation crossover for tighter control
• Room-Filling Authority: The bass depth that makes listeners wonder where you hid the subwoofer

Performance Characteristics

The Heresy IV doesn't just play music - it unleashes it. These speakers deliver the unconstrained, dynamic presentation that only horns can achieve. At 99dB sensitivity, they sing with just a few watts, yet handle 100 watts continuously. The soundstage extends beyond the cabinet boundaries with pinpoint imaging that places instruments in three-dimensional space. This is live music energy captured in American Walnut cabinets.
