HD1531
The HD1531 3-Way High-Definition Powered Loudspeaker
delivers 1800W of peak system power via Class-D Fast
Recovery™ amplification. Class-D amp design delivers up to
95% efficiency and, along with the lightweight switch-mode
power supply, drastically reduces loudspeaker weight.
Mackie High-Definition Audio Processing provides
unmatched sonic accuracy and clarity. Mackie Active
technology includes a precision 3-way crossover, transducer
time alignment, and phase correction. Plus, patented
acoustic correction algorithms harness the power of
proprietary measurement tools that identify sonic anomalies
that are inherent to all horn-loaded systems. Extremely
complex algorithms are then applied to the HD1531 to
counter these anomalies; this improves vocal intelligibility
while removing high frequency discord.
EAW custom-designed HD Series transducers maximize
efficiency and performance when matched with the system’s
internal amps. The 15-inch woofer uses a neodymium
magnet for reduced weight, and the 3-inch voice coil
dissipates heat extremely well. The 1.75-inch compression
driver and 6-inch midrange transducer are loaded into
Mackie’s wide-dispersion WaveFront™ system, which
ensures optimum intelligibility for every seat in the house.
The integrated 3-band contour EQ with a sweepable mid
allows the user to custom-tailor system tone for their
application or correct for common room anomalies. A bypass
switch provides easy implementation of a pre-set EQ.
The 15mm birch plywood enclosure is rugged and ready
for install using the 12 integral fly points. Standard M-10
eyebolts allow the HD1531 to be flown both vertically and
horizontally. The look of the HD1531 is understated and
the front LED can be defeated for maximum stealth. The
lightweight design of the HD1531 allows for pole-mounting
on a tripod stand or atop a subwoofer.
