Key Features
Product Ref: 297457
Since its initial launch in 2017, the QX series has undergone an engineering makeover. Now, Mission presents the second generation of QX speakers; still offering speakers which are a step above the entry-level LX series. Consequently, the QX MKII speaker range is ideal for those with a slightly higher budget and looking for extra technical specs.
Externally, the QX-1 MKII bookshelf speakers retain much of their predecessor’s design characteristics. Their cabinets feature similar detailing with smooth corners and a comb tooth texture around both driver units. However, the MKII speakers are now available in a choice of black, white, or traditional walnut finishes for greater styling versatility. In addition, enhancements have been made to cabinet rigidity, ultimately reducing any unwanted resonance.
Mission has opted for a new ring dome tweeter after expressing concerns that traditional domed diaphragm tweeters facilitate the inherent flaw known as cavitation. To avoid cavitation, Mission’s QX MKII ring dome tweeter attaches its voice coil partway down the textile dome. This reduces distortive effects for more impressive delivery of high frequencies – in excess of 20 kHz!
Mission brings an upgraded DiaDrive mid-bass driver to the QX-1 MKII bookshelf speakers where a seamless diaphragm is driven by a sub cone and connected voice coil for controlled and efficient mid-low frequency handling. Further improvements include ventilation for reduced resonance and a strong ferrite magnet for controlled direction of the magnetic field.
The comb-tooth detailing around the QX-1 MKII’s driver units is not merely for show; these serrations have been intricately optimised to minimise airflow interference and smooth frequency response. Indentations like these have also been incorporated into the rear reflex ports of speakers in the MKII series. These help to limit ‘chuffing’ noises typically associated with standard circular bass reflex ports.
Mission has positioned their drivers using inverted driver geometry, meaning the mid-bass driver is placed above the ring dome tweeter to assist with time alignment. This is a feature which Mission has trademarked since the 1980s. It is ultimately a calculated decision which helps the high and low ends of music reach your ears in a beautiful blend.
