Floorstanding loudspeakers — Mission ZX-5

The ZX-5 is the senior floorstanding loudspeaker in Mission's flagship ZX Series, built as the most technologically advanced design within the brand's current catalogue. Bearing a distinct ID intended to complement the finest electronics and decor, the ZX Series follows Mission's established philosophy that "music leads, technology follows" rather than the reverse.

Key specs that matter

Rated response is 36Hz to 24kHz at plus-or-minus 3dB, with bass extension to 30Hz at -6dB. Sensitivity is 91dB at 2.0V/1m, with a recommended amplifier power of 30-200W and peak SPL of 114dB. Impedance is 4 ohms nominal (8 ohm compatible) with a minimum of 3.4 ohms. Crossover frequencies are 570Hz and 2.5kHz. The three-way bass-reflex design uses two 6.5-inch (165mm) aluminium-cone bass drivers, two 5.25-inch (130mm) aluminium-cone midrange DiaDrive units, and a 1.5-inch (38mm) ring dome tweeter, all fed through a rear slot-port cabinet. Oversize magnet systems on the bass/midrange drivers deliver punch and transient attack suited to modern recordings, with special bracing methods developed to ensure the bass diaphragms respond accurately to the musical waveform. At 1155 x 265 x 400+12mm and 31.2kg per unit, the cabinet is finished in Gloss Black or Gloss White. Mission's Inverted Driver Geometry equalises acoustic path lengths between the treble and bass/midrange units, with IAG's Head of Acoustic Design Peter Comeau working to ensure seamless integration so the speaker behaves as a single coherent music-making system.

Sound and use context

Expect a dynamic, detailed and immersive listening experience with superior bass detailing and extension - the smooth, extended treble from the ring dome tweeter delivers refined, airy high notes, while the Inverted Driver Geometry creates a cohesive soundstage and wider listening sweet spot ideal for larger rooms and varied seating positions.

Pairing

The wide 30-200W recommended range admits both moderately powered and considerably ambitious amplifiers, though the demanding 4 ohm minimum-3.4-ohm impedance calls for genuine current delivery from whatever amplifier is chosen.

Alternatives

Mission's ZX-4 sits below this model in the same flagship ZX Series with dual 5.25-inch DiaDrive bass drivers rather than the ZX-5's larger 6.5-inch woofers, worth considering instead if this senior model's exceptional scale and 31.2kg weight exceed what a specific room requires.
