Mackie engineers, joined by audio gurus from EAW, worked hard to conceive of a way to preserve the all-important character of the original HR, while delivering performance—as well as appearance—that’s better than ever.
The HR624mk2 high-resolution Active studio reference monitors represent the evolution of revolutionary thinking.

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. The integrated Optimized Waveguide accurately and efficiently controls dispersion characteristics of the sound on and off axis, resulting in a wide sweet spot with smooth transitions from lows to highs. More inert than a wood or plastic baffle, the Zero Edge Baffle’s cast metal surface reduces surface vibrations during playback, thereby minimizing distortion to the sound’s waveforms; the result is improved time-domain characteristics, which equates to dramatically enhanced depth of field.
The HRmk2 is a bass reflex 6th-order system. Rather than use ports, the vent takes the form of a passive radiator, a mass-loaded flat piston coupled to the air trapped within the enclosure. You can’t see the passive radiator because it is located at the rear of the cabinet, behind the power amplifier assembly.
The HRmk2s have protection circuitry built in to protect from damaging input levels. With the same class A/B amplifier design as the original HR Series, the HRmk2s retain the much-loved character of our classic monitor, and carry on the Acoustic Space circuitry of the classic HRs, which allows you to tune the monitors to your room.
Designed into the heart of the amplifier circuits are EQ and filter sections that allow each amplifier to be precisely factory-tuned, ensuring that what we designed in our labs is what you end up with in your studio.
Each HRmk2 monitor features a high-precision, low-distortion woofer—6.7-inch for the HR624mk2—and a 1-inch ferrofluid cooled titanium dome tweeter.
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. Combining a wood cabinet with Mackie's metal Zero Edge Baffle adds that unquantifiable bit of warmth
, producing sound that’s true—and never lifeless.
Paint It Black
With the potential for the speakers to be used in settings from home theatres to gaming rooms to studios, we opted for a look that would be universally appealing. The high-gloss, piano black finish of the cabinet complements the deep charcoal grey of the Zero Edge Baffle, and gives the HRmk2 a modern, professional look that suits just about any environment. All HRmk2s ship with peelable, protective film on each side to ensure that they look as brilliant in your studio as they do when they leave the factory.
LED Power and Overload
Mackie's LED power indicator is a tasty shade of white—a cool, refreshing change from your typical red. Mackie 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. Mackie saved the red for when you’re overdoing it—you’ll see the scarlet HRmk2 overload LED when your input levels are too high.
Rotating Mackie Logo
Due to their ultra-wide sweet zone, the HRmk2 monitors can be oriented vertically or horizontally, sp Mackie made their logo rotate-able. (Yes, we thought of everything.) No matter which way you orient your HRmk2s, they’re always right-side up! Each HRmk2 also supplies Omnimount capability, so you aren’t forced to screw into—and damage—the enclosure’s surface in order to mount to the wall or from the ceiling.
Mackies goes to elaborate lengths to ensure each HRmk2 sounds as good as their experts intended. Each one they 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. Their Golden Reference Unit serves as the reference point for calibration; there is one of each model in the HRmk2 family. Hand-engineered in the US, the Golden Reference Unit is the master
for HRmk2 production units—it is the final design arrived at and approved by the HRmk2 team. The Golden Reference Unit and the test chamber are calibrated as a system every few hours, to compensate for temperature and humidity variations, and the resulting measurements are used to calibrate each HRmk2 production unit. Each HRmk2 monitor is tuned to be within 1.5 dB across the entire frequency range of the Golden Reference Unit, and gets its own birth certificate
with a chart plotting the frequency difference between it and the Golden Reference Unit. The birth certificate is then verified and signed by a Mackie Acoustic Technician.
Mackie's strict quality control means all their HRmk2s meet their published specifications, and that there is little-to-no variability between units. No matter if you get your first HRmk2 pair now and add another pair for your surround setup months later, you can be confident you have a precisely tuned system that has been designed to work in unison, and that every HRmk2 pair is a true matched pair
