Turn your studio's sweet spot into a full-on sweet zone.
The high-resolution Mackie HR824mk2 Active Studio Reference Monitor sounds as smooth as it looks. The rounded contours of the HR824mk2 monitor's Zero Edge Baffle minimize diffraction to give you a crystal clear audio image of your mix. The Mackie Optimized Waveguide delivers full, articulate mids, while the rear-firing, mass-loaded passive radiator ensures tight bass extension to 37Hz. Acoustic Space, low-frequency (LF) roll-off and high-frequency (HF) controls let you easily tailor the sound to suit your space and taste. And thanks to remarkably linear frequency response, Mackie HR824mk2 audio monitors ensure accurate mix translation. Combine all this with wide, even dispersion, and Mackie HR824mk2 monitors turn your studio's sweet spot into a full-on sweet zone.
