Mission QX-C MKII Centre Speaker

Mission QX-C MKII Centre Speaker

The Mission QX-C MKII Centre Speaker is a 2-way centre loudspeaker with two 5″ (135mm) bass drivers and a ring dome treble unit.

As per all Mission speaker concepts, the process of listening, listening and more listening is the key to improvement. With the added benefit of modern speaker design tools, such as computer-aided optimisation technology, crossover modelling, and laser interferometry, Mission engineers also spent considerable time fine-tuning the crossovers, components, materials, and construction.

Much like the now-established and equally class-leading Mission LX MKII series, the Mission QX-C MKII series takes an already phenomenal loudspeaker solution and refines it, optimises it, and brings even more vibrancy, finesse, and class through a process of evolution, not revolution.

QX MKII Drivers
An improved acrylic fibre cone material has been chosen for the QX MKII drivers. By it’s very nature, acrylic fibre is hard-wearing but offers a delicate appearance, in contrast of harsh driver materials seen in typical speakers of this price class. When implemented in the Mission DiaDrive System, the acrylic fibre brings natural mids and exceptional clarity. The seam-free curvilinear design features a conical support with a greater area of contact with the voice coil. This highly efficient and uncompromising system means the QX MKII series will excel in timing, with outstanding transient impact.

New look aluminium top plate
Aesthetically, the Mission QX-C MKII series introduces new Lux Black and Lux White matte finishes, along with the classic walnut pearl option. The new colour-coordinated aluminium top plate is more than just a visual ‘cherry-on-the-cake’; the added rigidity and support offered by this sturdy yet stylish addition further enhance the performance of the precision-engineered cabinets in this standout loudspeaker series.

Ring of Fire
Overcoming problems inherent in the physics of conventional domes, the ‘ring dome’ centre is fixed with a distinct and visible ‘phase plug’. This design enables extended HF reproduction by preventing cancellation along the centre axis of high-frequency waves produced near the diaphragm centre. The resonance experienced by traditional domes means that, at high energy, HF performance inevitably induces distortion. Managing this phenomenon inevitably reduces the HF capabilities in traditional domes, whereas the ‘ring dome’ is all but exempt from this complication. The result is better-controlled and much more consistent behaviour from 10kHz to 20kHz, and way, way above! Transient performance is dramatically improved, as is musical detailing, particularly of instrument overtones and harmonics.

Inverted Drive Geometry
Building on the QX styling, the Mission QX-C MKII is configured in the classic Mission IDG (Inverted Driver Geometry) format. By positioning the treble unit below the bass/midrange driver, the length of the path is equalised so the sound waves coincide at the listener’s head height. This principle improves ‘time alignment’.

QX MKII also takes the ground-breaking serrated driver surrounds to a new level. More than just a technical appearance or a pretty design touch, the surrounds have been improved through detailed airflow analysis and precise measurement. The new-look QX MKII surrounds help scatter reflections and reduce airflow interference, improving the silky-smooth performance of the drivers and ports.
