Subwoofers — Mission QX-12SUB MKII

The QX-12SUB MKII is a powered subwoofer from Mission's QX range, built to partner with the brand's QX-series main speakers. This model extends Mission's more developed QX engineering into the bass-reinforcement category, offering a capable companion to the brand's QX-series floorstanders and bookshelf speakers.

Position in line

It sits alongside the ZX-12 Sub in Mission's subwoofer hierarchy, within the QX product family. This positioning alongside the ZX-12 Sub suggests Mission offers subwoofers tailored to each of its main speaker ranges, with the QX-12SUB specifically voiced to complement the brand's QX-series speakers.

Key specs that matter

Rated response is 35 Hz to 120 Hz. The built-in amplifier is rated at 450 W. At 47.8 x 40.0 x 46.5 cm and 23 kg it is a substantial cabinet, consistent with the considerable amplifier power this model carries.

Sound and use context

Expect solid, well-controlled bass reinforcement suited to pairing with Mission's QX-series speakers - a capable performer likely voiced specifically to integrate seamlessly with the brand's own QX main speaker range.

Pairing

Standard line-level or speaker-level subwoofer inputs work with any stereo or AV receiver offering a subwoofer output, so it need not be restricted purely to a Mission-only system.

Alternatives

The ZX-12 Sub sits nearby in Mission's broader subwoofer range, worth comparing directly on cabinet size and specific main speaker pairing before choosing between these two closely related Mission subwoofers. Mission broader subwoofer catalogue gives buyers a reasonably clear set of options tailored to specific main speaker ranges, and a dealer conversation about the exact QX-series speakers already owned helps confirm this is the correctly matched subwoofer choice. Corner or wall placement remains the simplest way to reinforce output from a subwoofer of this kind. Overall this remains a sensible, well-matched choice for a Mission QX-series based home system. A phase switch, where fitted, is worth experimenting with to find the smoothest blend with the main speakers. A dedicated subwoofer cable run also helps avoid any hum introduced by a shared or undersized cable. Standard subwoofer level inputs should also be checked for compatibility with the specific main amplifier already owned. A dealer visit remains the simplest way to confirm current stock and pricing for this specific model.
