Mackie HR624 MK2 - 6" 2-Way High Resolution Active Studio Monitor
The HR624 MK2s have been redesigned with modern components for improved accuracy and an extended low-frequency response. The HR624 MK2 Studio Monitors are high-resolution, two-way, bi-amplified, active monitors employing a 6th-order Butterworth system with a built-in rear-firing mass-loaded passive radiator.There are many benefits to integrating an active crossover, power amplifiers, and drivers into single cabinet, and Mackie has taken full advantage of these benefits in the design of the HR624 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 over driving. In addition, the amplifiers’ gain and frequency responses are individually hand-trimmed to compensate for typical manufacturing tolerances between the drivers and produce a smooth frequency response from 45 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 compromised by the resistance of long speaker cables.The acoustic sum of the outputs from the two drivers are optimized electronically, as well as physically, so the amplitude response is unity and the phase difference is minimal.
Mackie 1604VLZ4 Key Features
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 internal reflections and dampen standing waves. Mounting hardware is installed on the bottom of the cabinet that fits the WB-60 OmniMount wall-mount bracket.
Power AmplifiersThe low-frequency amplifier produces up to 100 watts continuous before clipping, while the high-frequency amplifier produces up to 40 watts continuous.
