When John Atkinson took apart an original Epos ES 14 for Stereophile, he found almost no crossover, the circuit that splits the music between woofer and tweeter. The woofer was wired straight to the input terminals, and a single capacitor was stuck to the tweeter's magnet. Robin Marshall, who learned his speaker engineering at the BBC, designed his drivers to make that work, and Atkinson reports that Marshall believed a minimal crossover maximized dynamic range and detail. Thomas J. Norton called the ES 14 "superbly coherent" and said it "kept drawing me into the music." The current ES range, designed by Karl-Heinz Fink, uses a fuller crossover and a sloped front panel that lines the two drivers up in time. Steve Dickinson of Hi-Fi+ heard the ES14N as "lively, energetic, coherent and cohesive." Epos suits listeners who put timing and coherence first.

The range has three models, and the ES-14N stand-mount is the place to start. What Hi-Fi? calls its dedicated stands an "essential purchase" and preferred it about 90 cm from the rear wall with gentle toe-in. Anthony Kershaw of Audiophilia found its tonal balance on the warmer side of neutral. If your speakers have to go near a wall or on a shelf, look at the compact ES-7N. It was inspired by an East German speaker, the RFT BR 25, tuned for living rooms with no space for free-standing speakers, and a toggle on the back sets it up for stands or for a shelf. Holger Biermann of LowBeats ran a pair in an IKEA Kallax from a 300B tube amp of less than 10 watts, and What Hi-Fi? drove them from a 30-watt Rotel and heard them "kick like a mule" on Kendrick Lamar. Epos recommends the tweeters on the inside, and Fink advises listening with the grilles off. The ES-28N floorstander completes the range.

Robin Marshall founded Epos in 1983. Stereophile describes him as an ex-BBC engineer and onetime consultant to Monitor Audio, and Atkinson notes that he had played a small role in the BBC's LS3/5A. The larger ES 20 was his first model, but the smaller, ported ES 14 made the name, and Stereophile reviewed it in 1988, 1990 and 1995. Dickinson places the ES14 in the British "flat-Earth" school of the 1980s and 90s, alongside Linn's Kan and Sara, which prized dynamics, tunefulness and timing. Today Epos is based in Essen, Germany, and Fink, who has consulted for Naim, Tannoy, Wharfedale and Mission, designs its speakers. Fink told Fidelity that he came across an old interview in which Marshall said his speakers drew on the knowledge and ideas of their time, and he took that as his cue to push the boundaries rather than copy the past. What Hi-Fi? gave the ES14N full marks for sound, build and compatibility and said it set "the performance standards at this level," and the ES-7N won a What Hi-Fi? Award in 2026.
