A THX-approved, 6" high-resolution active studio monitor that offers powerful, accurate mix guidance.
The Mackie HR624mk2 high-resolution Active Studio Reference Monitor is the perfect alternative when space is limited. The HR624mk2 monitor offers the same design as the Mackie HR824mk2 in a more compact package. The new Zero Edge Baffle minimizes diffraction for a crystal clear audio image of your mix, and controls sound waves for wide, even dispersion. The Mackie HR624mk2 monitor's Acoustic Space, LF roll-off and HF controls let you easily tailor the sound to suit your space and your taste. Thanks to remarkably linear frequency response, with the HR624mk2 monitor, you always get accurate mix translation. Combine all this with superior bass extension, and the Mackie HR624mk2 monitor makes your studio's sweet spot a full-on sweet zone.
