Klipsch Model T Shorthorn: The Rare Experimental Horn That Paved the Way

Few names in high-fidelity audio carry the legacy of Paul W. Klipsch, the acoustical engineer whose obsession with efficiency, dynamics, and lifelike sound reproduction revolutionized loudspeaker design. Among his most celebrated creations are the Klipschorn and the later La Scala, but nestled in the experimental lineage between them lies a rare and historically significant model: the Klipsch Model T Shorthorn, introduced in 1955 as a bold departure from traditional speaker form and function.

Historical Context and the Birth of the Shorthorn

By the mid-1950s, Paul Klipsch had already established his reputation with the Klipschorn (launched in 1946), a corner-loaded folded horn speaker renowned for its extraordinary sensitivity and full-range performance in domestic settings. However, the Klipschorn’s large size and requirement to be placed in room corners limited its placement flexibility. Seeking a more versatile yet equally powerful alternative, Klipsch began experimenting with a shorter, front-firing horn design that could deliver high efficiency without the spatial constraints of corner loading.

The Model T Shorthorn, introduced in 1955, was the result of this experimentation. It was never intended for mass production—instead, it served as a prototype and limited-run testbed for new horn geometries and driver configurations. Built by hand in Klipsch’s workshop in Hope, Arkansas, fewer than 200 pairs are believed to have been produced, making it one of the rarest Klipsch models ever made. The “T” designation is thought to reference its transitional role—bridging the gap between the original Klipschorn and the future La Scala, which would adopt many of the Shorthorn’s innovations.

Despite its limited availability, the Shorthorn was demonstrated at audio shows and to select dealers, earning praise for its dynamic punch and clarity. Though it was ultimately superseded by the more refined La Scala in 1959, the Shorthorn remains a prized artifact of Klipsch’s engineering evolution.

Technical Specifications

Sound Quality Characteristics

The Model T Shorthorn was engineered for maximum efficiency and dynamic realism. With a sensitivity of 105 dB, it could produce concert-hall volume levels from just a few watts of tube amplifier power—making it ideal for the low-powered amplifiers of the era.

Sonically, the Shorthorn delivers a punchy, immediate presentation with exceptional transient response. The 15-inch folded horn woofer produces deep, articulate bass for its era, though not quite matching the sub-bass extension of the corner-loaded Klipschorn. The upper bass is full and warm, providing a solid foundation for orchestral and jazz recordings.

The Klipsch 832 compression driver, mated to a Tractrix horn, offers a bright, detailed, and highly dynamic treble. Early listeners noted its “lifelike” presence—particularly with vocals and brass instruments. However, the treble can be forward, requiring careful room placement and amplifier pairing to avoid harshness.

Overall, the Shorthorn’s sound is bold and unapologetic, favoring realism and dynamics over neutrality. It excels with acoustic recordings, big band jazz, and vocal performances—genres that benefit from its high resolution and low distortion.

Notable Features and Innovations

• Front-Firing Folded Horn: Unlike the Klipschorn, the Shorthorn did not require corner placement, offering greater setup flexibility while retaining horn efficiency.
• Tractrix Horn Geometry: The tweeter’s horn uses a mathematically derived Tractrix profile, reducing internal reflections and improving high-frequency dispersion—a hallmark of later Klipsch designs.
• Hand-Built Construction: Each cabinet was crafted from Baltic birch and solid wood, with meticulous attention to internal bracing and sealing.
• High-Efficiency Design: At 105 dB sensitivity, it remains one of the most efficient home speakers ever made.
• 16-Ohm Impedance: Matched to the output transformers of tube amplifiers common in the 1950s.

Market Value and Collectibility

Due to its experimental status and extremely limited production, the Klipsch Model T Shorthorn is a highly sought-after collector’s item. In recent years, original pairs in good condition have sold at auction and through private collectors for $8,000 to $15,000, with fully restored examples commanding even higher prices.

Collectibility is driven by:

• Historical significance as a transitional model
• Direct connection to Paul Klipsch’s personal engineering work
• Rarity (fewer than 200 pairs made)
• Growing interest in vintage horn speakers among audiophiles

Originality is key—speakers with original drivers, horns, and cabinetry fetch premium prices. Refinished cabinets or replaced components can significantly reduce value.

Common Issues and Maintenance

Owning a Model T Shorthorn requires careful stewardship. Common issues include:

• Aging Foam Surrounds: The original foam on the 15-inch woofers often disintegrates after 60+ years. Re-foaming or reconing is typically necessary.
• Tweeter Diaphragm Fatigue: The aluminum diaphragm in the 832 driver can develop micro-cracks. Testing with low-level pink noise can reveal distortion.
• Crossover Component Drift: Paper capacitors and older resistors may degrade, affecting tonal balance. Upgrading with modern audiophile-grade parts is common but controversial among purists.
• Cabinet Integrity: Check for warping, veneer lifting, or insect damage, especially in older walnut finishes.
• Horn Cracks: The Tractrix horn’s MDF or plywood construction can develop hairline cracks, affecting sound quality.

Maintenance best practices:

• Store in a climate-controlled environment
• Avoid direct sunlight to prevent veneer fading
• Use a soft cloth for cleaning; never use liquid cleaners on drivers
• Have drivers professionally tested before purchase
• Consider professional restoration for full refurbishment

Comparison to Similar Models

The Shorthorn strikes a balance between the Klipschorn’s bass depth and the La Scala’s forward placement. It lacks the Heresy’s mass-market appeal but exceeds it in dynamics and efficiency. Compared to contemporaries like JBL’s professional-grade systems, the Shorthorn offers a more integrated, home-optimized design.

Conclusion

The Klipsch Model T Shorthorn is more than a speaker—it’s a milestone in the evolution of high-fidelity audio. As an experimental model from Paul Klipsch’s golden era, it embodies the spirit of innovation that defined American hi-fi in the 1950s. While rare and demanding in upkeep, its breathtaking dynamics, historical importance, and connection to one of audio’s greatest pioneers make it a crown jewel for serious collectors and vintage audio enthusiasts alike.

For those lucky enough to hear a well-restored pair, the Shorthorn isn’t just a relic—it’s a living testament to the power of horn-loaded sound, delivering a visceral, emotionally engaging experience that few modern speakers can match.
