ZERO-EDGE BAFFLE™
The one-piece cast aluminum Zero Edge Baffle™ features precisely engineered curvature that minimizes diffraction for a crystal clear image of your mix, and effectively controls sound waves so you get detailed lows, full, articulate mids, and shimmering highs.
PRECISION AMPLIFICATION
The HRmk2 Series monitors contain separate onboard amplifiers for each driver, plus onboard active crossovers and time-correction circuitry, which helps ensure highs and lows reach your ears at the same time. The HRmk2s also have protection circuitry built in to protect from damaging input levels.
UNPARALLELED QUALITY
We go to elaborate lengths to ensure each HRmk2 sounds as good as our experts intended. Each one we manufacture is subject to rigorous testing and pre-screening during the production process, then calibrated and tuned with an environmentally controlled test chamber before final packaging.
ROTATABLE LOGO
Due to their ultra-wide sweet zone, our HRmk2 monitors can be oriented vertically or horizontally, so we made our Mackie logo rotate-able. No matter which way you orient your HRmk2s, they’re always right-side up!
PASSIVE RADIATOR
The passive radiator replaces the port found on most speaker systems. One primary advantage of a passive radiator is that it can reproduce low frequencies with lower distortion and at a higher sound pressure level (SPL) than a simple port or duct.
CABINET DESIGN
The HRmk2 monitors feature a wood cabinet, with custom internal bracing to increase its strength and rigidity in desired locations. To absorb internal reflections and dampen standing waves inside the cabinet, an open-cell adiabatic foam material is placed strategically inside the box.
POWER AND OVERLOAD LED
Our LED power indicator is a tasty shade of white and red for when things get pushed a little too hard. We took care to make sure the brightness is just right, too. The light shines bright enough so you can see it just fine in a well-lit room, and in a dark environment, it won’t distract or blind you.
Enclosure
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.
