The ES60 is a tower loudspeaker with a four-driver array: three 6.5-inch mica-reinforced polypropylene woofers and a 1-inch Terylene dome tweeter. A 2.5-way cascaded crossover, set at 2.4 kHz, joins the drivers. Frequency response runs from 32 Hz to 40 kHz, which meets the Hi-Res Audio certification, and sensitivity is 90 dB.

Bass output is supported by a patented Power Port design that guides air from the port into the room to reduce turbulence. The cabinet is built from damped MDF with laser-optimised internal bracing to limit resonances. A magnetic, anti-diffraction grille can be taken off for a different look.

The speaker connects through dual gold-plated five-way binding posts and works with 4 and 8 ohm amplifier outputs. Recommended amplifier power is 50 to 300 watts per channel. It is sold individually, and is listed as compatible with Dolby Atmos and DTS:X systems.
