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.

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. 

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.

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.

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.

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!
