Klipsch Model T Shorthorn (Experimental, 1955): The Compact Vision of Paul W. Klipsch

Paul W. Klipsch introduced the Klipschorn in 1946. It was a corner-loaded folded horn loudspeaker with unusually high efficiency, dynamic range and realism. By the mid-1950s he was already working on ways to get that sound into more practical, space-conscious forms. One of those explorations was the Model T Shorthorn (Experimental, 1955), a rare, little-documented prototype.

The Klipsch Model T Shorthorn was not a production model. It was designed during a period of rapid experimentation at Klipsch & Associates in Hope, Arkansas, as part of an effort to build a more compact alternative to the full-sized Klipschorn. The Klipschorn needed a room corner and a lot of floor space.

Historical Context: The Drive for Compact Horns

By 1955, the Klipschorn had a loyal following among audiophiles and recording engineers for its 105 dB sensitivity, full-range response and lifelike dynamics. Its size and strict placement requirements hurt its appeal in smaller homes and modern living spaces. Paul Klipsch began looking at truncated horn designs that could keep the high efficiency while cutting cabinet depth and overall footprint.

The Model T Shorthorn came out of that research. The "T" likely refers to its experimental classification within Klipsch’s internal naming system, and possibly means "truncated" or "tabletop." The Klipschorn used a folded bass horn extending deep into the corner of a room. The Shorthorn used a shortened horn path, giving up some low-frequency extension to be compact.

Detailed records of the Model T are scarce, which is typical for experimental units from this era. Surviving photographs, correspondence and collector accounts suggest that only a handful were ever built, possibly as proof-of-concept models for potential production or for evaluation by audio professionals.

Sound Characteristics and Performance

As a truncated horn, the Model T Shorthorn was a compromise between the full-scale Klipschorn’s bass and the space demands of a home. It could not reproduce the sub-40 Hz extension of its larger sibling, but it kept much of the horn-loaded efficiency and dynamic punch of the Klipsch approach.

Listeners familiar with vintage Klipsch designs would recognize the Shorthorn’s sound: lightning-fast transient response, effortless dynamics and a forward, engaging midrange suited to vocals and acoustic instruments. The shortened bass horn likely rolled off below 50 Hz. Placed near a wall or corner, it still gave solid lower-midbass presence, more than enough for the 78 RPM records and AM radio broadcasts of the era.

The high-frequency section used a smaller horn loaded with a 2" compression driver. It gave clarity and projection without the harshness sometimes associated with early horn tweeters. Paul Klipsch’s attention to time alignment and phase coherence kept the crossover region smooth and coherent, as in his other designs.

Notable Features and Innovations

Despite its experimental nature, the Model T Shorthorn had several forward-thinking features:

Truncated Folded Horn Design: A pioneering attempt to reduce cabinet depth while preserving horn loading efficiency.
Corner-Placement Optimization: Though smaller, it still benefited from boundary reinforcement, allowing it to deliver more bass than its size suggested.
Hand-Crafted Pine Enclosure: Built with the same solid-wood craftsmanship as the Klipschorn, reflecting Klipsch’s belief in acoustic integrity over cost-cutting.
Modular Crossover Network: Early evidence of Klipsch’s modular design approach, allowing for tuning adjustments during development.

The Model T also foreshadowed later Klipsch models like the La Scala (1963) and Heritage Series, which brought horn-loaded performance into more compact, versatile forms.

Common Issues and Maintenance

The Model T Shorthorn is so rare that maintenance guidance is largely speculative. Based on similar vintage Klipsch horns, potential concerns include:

Aging Compression Driver Diaphragms: The aluminum or titanium diaphragms in 1950s drivers may suffer from fatigue or corrosion. Re-coning or replacement with period-correct units may be necessary.
Woofer Surround Deterioration: The original foam or cloth surrounds on the 15" woofer are likely degraded. Modern restoration often involves replacement with butyl rubber surrounds.
Crossover Component Drift: Paper capacitors and older resistors may have drifted in value, affecting tonal balance. A careful recapping with modern film capacitors is recommended.
Cabinet Integrity: While built from solid pine, decades of humidity and movement can cause warping or joint separation. Stabilization and refinishing should be handled by a specialist.

There are no schematics or parts to work from. Restoring a Model T Shorthorn takes real expertise and access to Klipsch’s archival resources.

Current Market Value and Collectibility

The Klipsch Model T Shorthorn (Experimental, 1955) is virtually unobtainable. No confirmed units are known to exist in private collections, and none have appeared at auction. If one surfaced, it would likely draw intense interest from Klipsch historians, museum curators and high-end audio collectors.

As a prototype, its value lies more in historical significance than sonic utility. Conservatively, a fully restored and documented Model T could command $10,000-$20,000 or more in today’s vintage audio market, especially with original paperwork, blueprints, or provenance linking it to Paul Klipsch himself.

Collectors of Klipsch memorabilia, early horns, or American audio engineering artifacts would consider it a crown jewel.

Conclusion: A Glimpse into Klipsch’s Evolution

The Model T Shorthorn (Experimental, 1955) is more than a footnote—it is a testament to Paul W. Klipsch’s relentless pursuit of better sound. While it never reached production, it embodies the spirit of innovation that defined Klipsch’s legacy. It represents a moment when the boundaries of horn speaker design were being pushed, not for marketing, but for musical truth.

Though shrouded in mystery and scarcity, the Model T Shorthorn reminds us that even the greatest designs begin as experiments. For vintage audio enthusiasts, it symbolizes the daring, hands-on engineering culture of mid-century America—a time when one man in a small Arkansas workshop could change the way the world listens to music.

Today, as modern Klipsch continues to innovate, the spirit of the Model T lives on: the quest to deliver high-efficiency, high-fidelity sound in a form that fits real lives. And for those who seek the roots of that journey, the experimental Shorthorn remains a legendary, almost mythical, chapter in the Klipsch story.
