Mission is proud to introduce the QX-12SUB MKII 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 QX-12SUB MKII 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 QX-12SUB MKII also sports fantastic new Lux Black and Lux White finish options, to perfectly match the aesthetics of the stunning QX MKII Series loudspeakers.
