Klipsch Heresy 1 3-way speakers in gorgeous high end oiled walnut finish (HWO). Fantastic pair of the legendary heritage series Heresy I speakers in classic oiled walnut finish. Per the serial codes stamped on the cabinets, these were numbers 9 and 10 of the 1000 units built in 1979. The pair came from a single owner who maintained them in very good condition. The original paper tag is also present, and--while not in great condition--contains the handwritten names of the craftsmen that inspected and tested them. These are original condition showpieces with K-22 woofers, K-55v midrange drivers on K-700 horns and K-77 tweeters with Type E crossovers. We handbuffed these with pure tung oil to eliminate any slight uv fading and restore their original luster. Highly doubtful you'll find another pair in this condition unless you are buying them new. Immaculate, among the first 10 pairs made in 1979, and priced to sell.

Founded in 1946 in Hope, Arkansas, Klipsch traces its roots to Paul W. Klipsch, a visionary audio engineer and maverick who handcrafted his first speakers in a tin shed behind a dry cleaner. Patented in 1945, the revolutionary Klipschorn corner horn loudspeaker embodied his quest for live-like sound reproduction, drawing from Bell Labs principles to deliver wide frequency range and expansive soundstaging. This American pioneer shook hi-fi foundations, blending acoustic innovation with unyielding craftsmanship, and registered Klipsch & Associates to bring that tin-shed magic to the world.
Klipsch excels in loudspeakers, from flagship horn-loaded models like the enduring Klipschorn to high-fidelity enclosures, drivers, and complete systems for home audio, public address, and even personal computers. While deeply rooted in speakers, the brand has expanded into headphones and music systems, maintaining a focus on efficient, dynamic designs that prioritize clarity and power without excess amplification needs.
Renowned for its heritage-driven efficiency and bold, live-performance sonics, Klipsch holds a commanding mid-to-high-end position in the market, appealing to discerning buyers who value American-made authenticity over mass-market compromise. Neither purely vintage collector bait nor niche boutique, it bridges classic horn technology with modern reliability, earning cult status among audiophiles chasing that bigger, clearer sound Paul Klipsch first chased in 1946.
