Based on the QX-2 MKII, but built around a much larger floorstanding cabinet, the QX-4 MKII speakers hit hard. Working in conjunction with the larger cabinet, a second woofer helps drop the bass and increase the volume potential. If you have a larger room to fill, prefer your music loud or simply want the effortless bass that goes with floorstanding speakers, the QX-4 MKII is hard to beat.Featuring Mission’s ‘ring dome’ tweeter design, these speakers offer the perfect balance of stunning musical detail with a smooth, low distortion output. Thanks to a twin cavity venting system, backpressure is reduced, meaning the treble response can ‘breathe’. Offering low resonance and the purest detail, the QX speakers are a class above at the top end.With an improved hybrid blend of soft pulp and acrylic fibre, the seam-free woofer is designed for effortless movement and maximum clarity. For the dynamic thrill you’d expect from Mission speakers, a clever DiaDrive, sub cone system transfers maximum transient impact directly from the motor system – meaning that the crack of a drum is crisp and instantaneous.Mission have put much work into the QX-Series MKII to reduce distortion. Computer optimised modelling and laser interferometry make this MKII even better than the original. As well as the vented treble unit and DiaDrive woofer, a slot port system enhances airflow leaving the cabinet. Reduced pressure here enhances the low frequency response without introducing distortion.
