KLH Audio Model Five Standmount Loudspeakers Ex-Demo, Great Condition. New stock is currently unavailable, so will replace these with a different finish once they're back in stock. Product Information: Iconic Mid-Century Modern Styling Acoustic Suspension Design – The most accurate and linear enclosure design available today Three-Position Acoustic Balance Control to tailor the loudspeaker’s output for the most difficult acoustic environments Dedicated midrange driver to reproduce the critical mid-frequency band Non-Resonant Die-Cast Aluminum Midrange & Woofer Frames Machined Aluminum 1” twe
Timing is decent but not special: this is a well-established vintage speaker, so the value is driven more by condition and completeness than by product age or a replacement cycle. At A$3,600, it sits above the A$3,140 median and just over the A$3,364 75th percentile of the recent AUD comps, so this is ambitious, not a bargain.
That said, it’s a respected design with a strong reputation for a full, musically engaging presentation, especially when the cabinets, drivers, and crossover parts are healthy. If it’s clean, original, and fully sorted, the upside is owning a classic that still has real enthusiast appeal; but at this price, I’d want evidence of proper restoration, matched drivers, and intact cosmetics before calling it easy money.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
