MACKIE HR624 MK2 STUDIO MONITOR (PAIR)

Back in the ’90s, our HR Series studio reference monitors revolutionized studio monitoring. With their incredible sound quality and affordability, they earned a wide and loyal following, fast becoming the industry standard. Today’s studio demands a monitor that can reproduce sound as precisely as it is recorded. The same innovation that launched our pioneering HR Series has led to the birth of just such a monitor as well as a new studio standard. Meet the HRmk2.

SPECIFICATIONS (EACH):

Materials and Construction:

3/4-inch (19 mm) thick MDF cabinet construction with internal

bracing to add to cabinet stiffness.

Piano-black gloss finish.

Die-cast aluminum exponential wave guide for controlled, wide

dispersion from high-frequency driver and Zero Edge Baffle™ to

minimize diffraction around the cabinet edges.

Open cell adiabatic “foam fill” acoustical damping material absorbs

internal reflections, preventing delayed sound coloration.

Flush-mount connector system allows monitor to be placed

against a wall without need for connector clearance
