KLH Audio officially unveiled Model Four at High End Vienna 2026, the latest addition to its Model Collection. Model Four is an eight-inch, three-way acoustic suspension loudspeaker that combines the small footprint of Model Three and the sonic architecture of Model Five.

KLH said that Model Four unites the defining strengths of the Model Collection. The solution is built around the eight-inch woofer introduced in Model Three and shares the same midrange driver, tweeter and crossover architecture as Model 5, aiming to deliver the refined vocal presence, midrange clarity and high-frequency detail. The cabinet features the wide baffle and shallow depth proportions of Model Seven.

Model Four is the shallowest solution in the collection with a total depth of under 11 inches, and was designed to complement any space with placement flexibility and modern aesthetics. The solution features a three-way acoustic system that the company said was engineered to provide high performance at a price point of $1,999.

An 8-inch pulp-paper cone woofer with reverse roll rubber suspension works in tandem with a 4-inch pulp-paper cone midrange and 1-inch aluminum dome tweeter in an effort to produce a dynamic, full-range presentation. A three-position Acoustic Balance Control switch—a KLH original introduced in the 1960s—allows listeners to fine-tune the speaker’s mid and high-frequency character to suit every room.

KLH said that the Model Four will be available in the U.S. and select international markets beginning in September 2026. The solution will be on display and available for listening at KLH Audio’s suite #1415 at Meliá Vienna throughout High End Vienna 2026.

“Model Four represents exactly where KLH is headed: honoring the acoustic principles that made this brand stand out while designing products for how people actually live and listen today,” said KLH Audio CEO Scott Hagen. “This is not a bookshelf speaker, nor is it simply a smaller Model Five. It is a distinctive, full-range acoustic-suspension loudspeaker, meticulously built to deliver the natural, controlled and room-friendly sound that defines KLH in a form that fits more homes, rooms and listeners. Our responsibility is to protect the integrity of this brand while moving it forward, and Model Four is a major step in that direction.”
