HD1521
The HD1521 2-Way High-Definition Powered Loudspeaker
delivers 1600W 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 2-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 HD1521 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 utilizes heat-treated titanium, which provides
increased diaphragm rigidity, eliminating distortion that can
occur due to surface inconsistencies.
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 HD1521 to be flown both vertically and
horizontally, and its 80° x 50° horn can be rotated 90° if
desired. The look of the HD1521 is understated and the front
LED can be defeated for maximum stealth. The lightweight
design of the HD1521 allows for pole-mounting on a tripod
stand or atop a subwoofer.
APPLICATIONS
Small to mid-size club/band PA systems, houses of worship,
DJs, rehearsal spaces, gymnasiums, banquet halls,
A/V rentals and many, many more.
