TECHNICAL INFORMATION

HR624 MK2 Specifications
Enclosure
Materials and Construction:
⁄ -inch (19 mm) thick MDF cabinet construction with internal
3
4
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.
