This is a buyer’s market for vintage KLH speakers right now, and the US$290 asking price for this used KLH Audio Model 5 is a strong deal, sitting just below the 25th percentile of US$254 from our recent comparable listings. While the 75th percentile jumps to US$2,249, the median of US$290 confirms this listing is priced exactly at the fair market midpoint, making it an excellent entry point for a well-loved classic without the premium attached to rare or restored pairs.
The original KLH Model Five (1968–1977) is a revered four-driver, three-way acoustic-suspension speaker known for its smooth, balanced sound and easy driveability on 6-ohm nominal impedance. It delivers solid low-end extension down to 32Hz and handles power well, making it a timeless choice for mid-century design lovers who value tonal accuracy. At US$290, this is a clear buying opportunity for a fellow enthusiast looking to grab a genuine vintage KLH with meaningful upside, assuming the condition is as described and no major repairs are needed.

KLH Audio traces its origins to 1957 in Cambridge, Massachusetts, where audio pioneer Henry Kloss joined forces with Malcolm S. Low and Josef Anton Hofmann to form KLH Research and Development Corporation. Kloss, renowned for co-developing the acoustic suspension loudspeaker—a breakthrough that delivered superior bass from compact enclosures—propelled the brand to global dominance. By the early 1960s, KLH had become the world's largest loudspeaker manufacturer, employing over 500 people and distributing to six continents, with iconic innovations like the Model Nine full-range electrostatic speaker, the high-selectivity Model Eight FM radio, and the portable Model Eleven solid-state record player.
The brand's focus remains squarely on loudspeakers, blending heritage designs with modern engineering for two-channel stereo and home theater systems. Revived in 2019 under president David P. Kelley after decades of ownership changes, today's KLH reissues classics like the Model Five while introducing fresh models emphasizing acoustic suspension principles for accurate, room-friendly performance. Unlike broader audio categories such as amplifiers, turntables, or headphones, KLH prioritizes premium speaker categories rooted in its foundational expertise.
KLH occupies a respected mid-tier position in the hi-fi market, appealing to discerning buyers seeking high-value performance without ultra-high-end pricing. Its reputation endures among audiophiles for timeless sound quality, precision craftsmanship, and a legacy of democratizing superior audio—evident in its role introducing Dolby to consumer tape decks. Now headquartered in Noblesville, Indiana, KLH balances vintage allure with contemporary reliability, positioning it as a smart choice for knowledgeable enthusiasts building enduring systems.
