Introduction

Thank you for choosing the Mackie HD1801 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, HD1801 subs deliver 1600W peak power via high-output 18” drivers custom-designed for optimal pairing with Mackie full-range loudspeakers. The HD1801 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 HD1801 with any Mackie full-range loudspeaker for an extremely powerful and fully high-definition PA solution.

Paired with a Mackie HD Series loudspeaker, you have a complete (and completely affordable) “plug and play” system that is ideal for small clubs, DJs and rehearsal spaces. The HD1801 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. You can fly it using the integrated M10 flypoints. Or you can just stack your full-range box right on top of the sub...the HD1801 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.
