The ZX Series is the latest in a long line of distinguished and revered Mission loudspeakers and joins more recent Award winning products. The ZX series represents the most technologically advanced loudspeakers in the Mission family, with a distinct ID that will complement the finest electronics and décor.

Mission ZX incorporates purpose designed bass driver cones, precision engineered motor systems, advanced treble units and more. As ever with Mission products; ‘Music leads, Technology Follows’. No compromise.


Mission’s Ring Dome treble unit overcomes the problems inherent in conventional domes. With this technology the centre of the dome is fixed and voice coil attached part of the way across the dome. The dome is formed into two rings, with the voice coil in the centre so that it can drive the dome more accurately and efficiently.

The result is lower distortion and superior performance, at frequencies up to 30 kHz and beyond. Transient performance is dramatically improved, as is musical detailing, particularly of instrument overtones and harmonics.


Mission ZX-5 MKII Floor-standing Speaker Drivers


Mission’s DiaDrive bass unit has an advanced aluminium matrix cone and is now vented to remove trapped air behind the diaphragm, thus reducing resonance and allowing a clearer midrange performance to beyond 3kHz.


In ZX the driver surround is covered by a vented cover which controls the spurious output from the diaphragm edge, again improving midrange clarity.


Matching ‘serrations’ are built into the flare of the slot port. High pressure airflow is streamlined from the port exit whilst the asymmetric design breaks up the ‘chuffing’ distortion normally heard from circular ports.

Mission ZX bass/midrange units now feature, as standard, over-size magnet systems to deliver the punch and transient attack that feature in modern recordings.


To improve the mechanical integrity of these magnet systems, special bracing methods have been developed to ensure that the bass diaphragms respond accurately to the musical waveform. Bass output is now thrillingly dynamic with superior detailing and extension.

Mission’s Inverted Driver Geometry (IDG) of bass/midrange and treble units has been applied to equalise acoustic path lengths. IAG’s Head of Acoustic Design, Peter Comeau, has worked tirelessly to ensure a seamless integration between the drive units, so the speaker behaves as one music making system.


Designed to stand out head and shoulders above the competition, the Mission ZX range oozes luxury in appealing gloss black and gloss white finishes. Carefully selected trims and driver materials do more than catch the eye and complement the technology at play. The Mission ZX series has an all-inclusive design that continues to tell the story of the music, not just deliver hi-fi sound.
