Product Description for the Mackie HR824-MKII Studio Monitor

We began producing the original HR824 Studio Monitors in 1997, and they quickly became the standard by which near-field studio reference monitors were compared for extremely flat frequency response at a reasonable price. The HR824 MK2s have been rede- signed with modern components for improved accuracy and an extended low-frequency response.

Investments in Excellence... When we decided it was time to update the HR824s, we turned to our expert loudspeaker and transducer de- sign engineering team at EAW to determine how to make an already excellent studio monitor even better. The first thing they noticed was that the front baffle could be redesigned with a rounder aluminum construction to further reduce edge diffraction for improved imag- ing. The volume of the cabinet was increased slightly to improve the low-frequency response. The amplifiers have been adjusted with all new ‘voicing’ to match the new cabinets. However, the amplifiers’ design is fundamental- ly the same and has a very similar characteristic to the original model. If you are upgrading from the original HR824s, you won’t have to relearn the sound. The MK2s still deliver the clarity, ultra-linear frequency response, and broad stereo imaging of the originals.

An elegant piano-black gloss finish emphasizes that these studio monitors are in a class by themselves, pleasing to the most discerning eye as well as the most discerning ear.

The result? The HR824 MK2 Studio Monitors are extremely accurate and versatile, loaded with unique con- trols that allow you to fine-tune the sound to match your individual environment precisely. You’re gonna love these!

What are they? The Advantages...

The HR824 MK2 Studio Monitors are high- resolution, two-way, bi-amplified, active moni- tors employing a 6th-order Butterworth system with a built-in rear-firing mass-loaded passive radiator. Whew! There are many benefits to integrating an active crossover, power amplifi- ers, and drivers into a single cabinet, and we’ve taken full advantage of these benefits in the design of the HR824 MK2.

  • The crossover point is designed so that the high- and low-frequency drivers are fed only the frequencies they are best able to reproduce.
  • The amplifiers are designed to provide maximum acoustic output from the speakers, yet minimize the danger of speaker damage due to overdriving.
  • In addition, the amplifiers’ gain and frequency re- sponses are individually hand-trimmed to compen- sate for typical manufacturing tolerances between the drivers and produce a smooth frequency response from 35 Hz to 20 kHz.
  • The connecting wires between the amplifier outputs and the drivers are kept to an absolute minimum, so the damping factor of the amplifier isn’t compro- mised by the resistance of long speaker cables.
  • The acoustic sum of the outputs from the two driv- ers are optimized electronically, as well as physi- cally, so the amplitude response is unity and the phase difference is minimal.

In short, all the complex interconnected components in the system are designed to work in harmony with each other to produce the best possible sound.

The Transducers...

The monitors feature an 8.75-inch high-precision, low- distortion woofer and a 1-inch ferrofluid cooled titanium dome tweeter on the front, and a 6-inch x 12-inch ellipti- cal flat piston passive radiator in the back.

The high-frequency driver is mounted on a massive, acoustically non-resonant die-cast aluminum exponential waveguide, which results in wide, controlled dispersion of high-frequency sounds. The unique passive radiator design provides tight, articulate bass response down to 35 Hz — an astounding accomplishment for a cabinet of this size! And since the radiator is producing most of the sound at the lowest frequencies, there is very little distortion from the woofer because its cone movement is minimal at those frequencies.

The Cabinet...

The cabinet is made of MDF with a high-gloss piano- black finish. Internal bracing increases the strength and rigidity (stiffness) of the box. An open-cell adiabatic foam material fills the inside of the box to absorb inter- nal reflections and dampen standing waves. Mounting hardware is installed on the bottom of the cabinet that fits the 60.0 WB OmniMount wall-mount bracket (see “Placement” on page 6 for more info).

FR Series Power Amplifiers...

What better way to power the loudspeakers than with our acclaimed FR Series “Fast Recovery” power amplifi- ers. Our Fast Recovery design uses low negative feed- back, yet allows the amplifiers to maintain low distor- tion and stability even when driven into clipping. The low-frequency amplifier produces up to 150 watts continuous (350 watts peak) before clipping, while the high-frequency amplifier produces up to 100 watts continuous (210 watts peak).


The HR824 MK2s were designed to be placed in a vertical position. If you find it necessary to place the speakers in a horizontal position (on their sides), place them so that the woofers are toward the inside; that is, so the woofers are closest to each other. This provides the best low-frequency summing and overall imaging. The HR824 MK2s may also be wall-mounted using the mounting hardware located on the bottom of the cabinet. These are currently designed to be used with the OmniMount 60.0 WB (Wall-to-Bottom) wall-mount bracket, which provides a wide range of horizontal and vertical movement to meet your coverage requirements. However, many companies change specifications without notice.
