Mission M31i
2-way bass-reflex bookshelf speaker from Mission, recognised for its musicality and awarded a Diapason d'Or in 2005.
Description
The Mission M31i is a compact bookshelf speaker built around a 2-way bass-reflex design. It is aimed at music lovers seeking a faithful rendering of tone rather than a spectacular effect, in a format suited to a modestly sized home installation.
The 130 mm woofer, using DiaDrive technology, works in tandem with a 25 mm Viotex dome tweeter fitted with FF cooling designed to withstand demanding use without degrading tonal quality. This pairing covers a stated frequency response of 65 Hz to 20 kHz, placing this speaker firmly in a particularly refined midrange-to-treble register, with a present but not extreme bass, the latter being reserved for larger-volume speakers.
In terms of listening character, the M31i stands out for a natural midrange, free of colouration or any sense of constriction, and a treble described as refined. Its tonal accuracy and instrumental realism make it a speaker geared towards musicality rather than technical showmanship, with a lively dynamic and good reproduction of fine nuances. This profile earned it the Diapason d'Or 2005 award from Diapason magazine.
This model will suit a listener who favours acoustic or vocal music, in a reasonably sized living room or office, paired with an integrated amplifier or a compact system. Its bookshelf design makes it intended for placement on a cabinet or stands rather than a floorstanding installation.

What to check before buying used
The 130 mm DiaDrive woofer warrants a check of the surround, which is often prone to hardening or cracking with age, as is the tweeter's Viotex dome, which should show no deformation or signs of being pushed in. Check for any unwanted noise or distortion at moderate volume, which would indicate a fault with the magnet or the voice coil. The cabinet and bass-reflex ports, sensitive to knocks and humidity, should be free of cracks or veneer lifting in order to preserve the enclosure's acoustic tuning.
