Serious hi-fi speakers have long demanded a certain kind of listener, one with a dedicated room, a generously sized space, and the freedom to place enclosures wherever the acoustics dictate. That’s a fine arrangement for a fortunate few, but most people live in apartments, condos, and first homes where the furniture stays where it is, and the speakers need to fit around it, not the other way around.
KLH Audio has spent nearly seven decades building speakers for exactly that reality, and the Model Four is its latest expression of it. Unveiled at High End Vienna 2026, it’s a three-way acoustic suspension loudspeaker designed to fill the gap between the bookshelf-sized Model Three and the fuller Model Five, bringing genuine floorstanding performance into a cabinet compact enough to sit comfortably close to a wall.
Designer: KLH Audio
The technology that makes this possible is acoustic suspension, the sealed-enclosure design that KLH pioneered in the 1950s. Unlike ported enclosures, which become muddy and bloated when pushed against a wall or tucked into a corner, a sealed cabinet performs consistently wherever it lands. The Model Four delivers tight, accurate bass with just a few inches of rear clearance, a freedom that ported designs simply can’t match.
The cabinet measures 26 inches tall and just 8.25 inches deep, making it the shallowest floorstanding speaker in KLH’s lineup. The included 6-degree slanted riser adds the angle needed to align the tweeter and midrange with the listener, bringing the total depth to just under 11 inches. That’s narrower than many bookshelves and considerably thinner than the floor plans most audiophile floorstanders require before they’ll sound right.
Inside the sealed, reinforced MDF enclosure is a three-driver system assembled from the best parts of the broader Model Collection. An 8-inch pulp-paper cone woofer reaches down to 46Hz, a 4-inch pulp-paper midrange handles vocals and instruments with the same clarity that earned Model Five its reputation, and a 1-inch aluminum dome tweeter extends the response to 20,000Hz. Power handling reaches 150 watts, with peaks up to 600 watts.
Not every room sounds the same, which is why KLH carried over its three-position Acoustic Balance Control switch, a feature the brand introduced in the 1960s. It gives listeners a way to adjust the mid and high-frequency character to match their room’s natural acoustics, a practical acknowledgment that the speaker will land in spaces KLH can’t anticipate. Five-way gold-plated binding posts handle connectivity on the back panel.
The visual side of the package is equally considered. KLH’s mid-century modern design language shows up in the knit grilles and wood-veneer cabinetry, available in English Walnut with a Stonewash Knit Grille, Black Ash with a Grey Knit Grille, and White Oak with a Black Knit Grille. The matte black riser stand ships with the speaker, keeping the total out-of-pocket cost honest from the start.
The Model Four arrives in September 2026 through premium audio dealers and directly from KLH Audio, priced at $999.99 per speaker, or $1,999.98 per pair, with a 10-year warranty and the riser stand already included. For anyone who has spent years making peace with bookshelf speakers because larger alternatives demanded a dedicated room, it’s the kind of offer that closes the argument.
