Epos Acoustic M22i Floorstanding Speakers

Epos Acoustic M22i FloorStanding Speakers.

The current flagship of the Mi range of speakers, the 2 ½- way M22i, has deeper bass and higher power handling than the M16i. In designing the M22i, the Epos engineering team designed a high performance two channel speaker that would be equally at home in a home theatre application.

The M22i uses the revised Epos 25mm (1 in.) low distortion metal dome tweeter, designed for smooth, clear and extended treble. The upper frequency crossover is centred on 5kHz and the minimalistic 1st order crossover is simply a polypropylene film capacitor.

Epos has designed a robust new 165mm (6.5in.) mid-range woofer with die-cast aluminium alloy chassis, phase plug and moulded polypropylene cone. Its curved cone profile and graduated thickness were engineered to ‘roll off’ high frequencies mechanically, in a smooth fashion. It also has very high power handling. As such, the woofer requires no electrical crossover (neither high pass, nor low pass) to reproduce dynamic, natural bass and mid-range frequencies in this model.

The mid-range driver runs in a sealed chamber, with the tweeter. It is designed to naturally roll-off around 80Hz, with useful output below that. The woofer and mid-bass output overlap and work effectively as one bigger unit. This reinforces the power and dynamics of this compact speaker.

The 165mm (6.5in.) bass driver is similar to the midrange but has a weighted dust cap instead of a phase plug. It is mounted in a separate chamber in the lower section of the cabinet and is loaded with a rear-firing port, flared at both ends for low turbulence and minimal distortion. It is also filtered by the crossover to limit frequencies above 100Hz.

Together, the woofer and mid-range units handle very high powers. We recommended that the M22i should be partnered with an amplifier that is capable of driving a four Ohm load to high levels.
