The Mackie MR624 Studio Monitor is a powered 6.5" 2-way reference speaker that is designed for mixing and monitoring in your home or project studio. It features a logarithmic waveguide system that aims to minimize reflections and diffractions for a wider sweet spot, plus a custom-tuned rear port to help ensure an even bass response. The MR624 is equipped with matched amps and drivers for an optimized 65W Class-A/B bi-amplified system. The speakers can also be optimized to your mixing environment with the adjustable acoustic space filters designed to maintain a flat response in typical placement configurations. Additionally, a high-frequency filter applies a boost or cut to compensate for particularly bright- or dull-sounding rooms. The MR624 has been designed with flexibility in mind, featuring XLR, TRS and RCA monitor inputs. The speaker has been housed in an all-wood cabinet that has been treated with acoustic absorption material for a tighter response. Additionally, the MRS10 studio subwoofer can be added for a more powerful, extended low end.
