Introduction
Thank you for choosing the Mackie HD1501
subwoofer. Mackie HD Series Powered Subwoofers
provide intense low-frequency extension and punch to
any Mackie full-range system. Designed and tuned by
the experts at EAW, HD1501 subs deliver 1200W peak
power via high-output 15" drivers custom-designed for
optimal pairing with Mackie full-range loudspeakers.
The HD1501 incorporates Mackie-standard professional
components like efficient Class-D Fast Recovery™
amplifiers and system-optimizing Active electronics so
that everything sounds great right out of the box.
Premium circuitry includes a symmetrical Linkwitz-
Riley crossover, precision tuning filters and user-friendly
features like high pass outputs for stereo operation with
a single sub. The 15mm birch plywood enclosures
feature a ported, direct-radiating design for chest-
pounding punch. Pair the HD1501 with any Mackie
full-range loudspeaker for an extremely powerful and
fully high-definition PA solution.
Paired with a Mackie HD1521, you have a complete
(and completely affordable) "plug and play" system that
is ideal for small clubs, DJs and rehearsal spaces. It is
also a great match when paired with the popular Mackie
SRMv2 Series and can easily integrate into nearly any
existing PA setup. The HD1501 has both full-range and
high-pass stereo outputs for connection to full-range
top boxes. Just dial in the appropriate level and use the
polarity switch to make sure the sub is in phase with the
loudspeakers. The integrated pole-cup can
accommodate a standard mounting pole, so your
favorite speaker has a nice place to sit. Or you can just
stack your full-range box right on top of the sub...the
HD1501 ain't picky.
So if you are looking for an extremely powerful,
affordable PA setup that is simple to use, then you're in
the right place. Read on to learn everything you could
possibly want to know about your new subwoofer.
