Mission QX-12SUB MKII Subwoofer
Mission is proud to introduce the Mission QX-12SUB MKII Subwoofer to complement the latest QX MKII Series of loudspeakers.
Perfect for a QX MKII Series home-theatre system or musical bass extension in 2-channel applications, the Mission QX-12SUB MKII Subwoofer utilises a 12-inch (300mm) long-throw bass driver with astounding bass impact. Based on the same award-winning system found in the best-selling QX-12SUB, the Mission QX-12SUB MKII Subwoofer also sports fantastic new Lux Black and Lux White finish options, as well as classic walnut pearl, to perfectly match the aesthetics of the stunning QX MKII Series loudspeakers.
High Power Amplifier
The built-in amplifier is optimised for high impact at low frequencies. The fast response and high-power performance is perfect for movies or music.
No-Presses Paper Cones
A specially engineered 12” paper cone with increased self-damping properties offers an increased structural rigidity of the cone itself for a fuller performance and massive bass impact.
Low Pass Filter Slope
Continuously adjustable from 35Hz to 120Hz (@33dB) for seamless acoustic integration with your speaker’s performance.
High Sensitivity & Versatility
Low-level inputs, output connections and a dedicated LFE input are provided. Additionally, the auto power sensor is sensitive enough to detect incoming signals of extremely low levels for automatic activation of the subwoofer when required.

I recently added the Mission QX-12SUB MKII Subwoofer to my setup and it’s been incredible. The bass is deep, clean and powerful without ever feeling boomy. Movies and music feel more immersive and the sub blends perfectly with my speakers. Totally worth it.

I’ve been using the Mission QX-12SUB MKII Subwoofer for a month now and it’s genuinely transformed my home audio setup. It handles bass notes smoothly without any rough edges. Even at low volumes it adds a nice fullness to everything I play. It’s a reliable, impressive subwoofer that I’m glad I chose.
