THE HISTORY OF KLH & THE MODEL THREE KLH Audio was established in 1957 by Henry Kloss, Malcolm Low, and Josef Hofmann. Henry Kloss first made his name in Acoustic Research with the AR-1 and its patented acoustic suspension system that revolutionized the high-fidelity industry. Kloss later left Acoustic Research to start KLH, where he immediately began marketing his acoustic suspension loudspeaker designs. Throughout the 1960s and 1970s, KLH was the top seller for acoustic suspension loudspeakers. Several models were very successful during that time and continue to be held in high regard for their tonal accuracy and precision today. The KLH Model Three is an all-new acoustic suspension loudspeaker model, first introduced in 2022. This loudspeaker will carry on the legacy of accurate audiophile-quality performance while delivering great value to the customer. ACOUSTIC SUSPENSION First introduced in 1954, the acoustic suspension principle has long been considered the most accurate of all loudspeaker designs. The original AR-1, the well-known AR-3, and various later models were all brought to market by Edgar Villchur and Henry Kloss. Several brands, including KLH, would adopt the acoustic suspension principle and use it in their loudspeakers designs for many years to come. This design principle dominated the speaker market well into the 1970s. In an acoustic suspension design, the air volume inside the enclosure serves as a cushion of air, or air spring, to provide a restoring force for the woofer cone. The said air inside the enclosure becomes the dominant part of the woofer’s suspension. Because the air volume inside the enclosure is more linear than the mechanical parts of the woofer’s suspension, the woofer’s diaphragm can move more linearly. This linear movement enables the driver to operate at higher excursions with less distortion than traditional bass-reflex systems. Acoustic suspension systems receive worldwide praise for their greater accuracy, tighter bass transients, and exceptional bass resolution and texture. TWO-WAY DESIGN The KLH Model Three is a compact, 2-way system that provides full-range sound to average-sized listening spaces. KLH designed an 8” woofer specifically for this 2-way system, and it features a smooth and extremely accurate response up to 1,600 Hz. This woofer delivers clear vocals and offers rich reproduction of lower midrange instruments- all while minimizing distortion. Meanwhile, the 1” tweeter provides a smooth extended response with low distortion. The dispersion characteristics are polished and natural, which is crucial for a large and accurate stereo image.
