Mackie Professional Audio
HD1501, High-Def. Powered Loudpseakers

Portable, Professional PA
Just pair up the HD1501 Powered Subwoofer with any HD Series full-range loudspeaker for an extremely portable PA that delivers unmatched clarity and eliminates the need for tons of expensive and heavy outboard gear. The precision-tuned HD1501 is a perfect match for the top boxes, with a high-pass output specifically designed to alleviate the power-hungry low frequencies from getting to your top boxes, allowing them to do what they do best. The entire system features protective circuitry including peak and RMS limiting, over-excursion and thermal protection to keep those lows pumping at all costs. It’s also a great match for your SRM450v2.

Power and Agility
The HD1501 Powered Subwoofer delivers 1200 watts of peak power using Mackie’s Class-D Fast Recovery™ amplification. Class-D amps allow for extremely high-output in a design that is much lighter than traditional amplifiers. Normally, a sub that can push that kind of power is no fun to lug around. Okay, we can’t promise a fun load in, but we can say that your subs are now probably lighter than your bassist’s rig. It’s also really compact, which means you might even be able to carry it all by yourself…sorry roadies. Plus, our Fast Recovery™ design allows the amplifier to recover more quickly when pushed into clipping. This means less distortion when things get too loud. Hey, we would just tell you to turn it down, but we’re not the cops or your old man neighbor.

Tweaked and Tuned
Mackie has once again called on the sonic geniuses over at EAW to make the HD1501 the most punchy, chest-pounding subwoofer in its class. The ported, direct-radiating design means super-low frequency extension that is smooth and powerful. EAW also custom specified the 15˝ driver to work in perfect harmony with the amplifier. Some of the other guys claim high wattage, but use limiters to reduce the amount of actual power that hits the speaker. That’s like buying a 40-year-old single malt scotch and mixing it with Mountain Dew. We would never do that to you… the woofer is designed to soak up each and every bit of power the amp puts out. Precision phase control and tuning filters make the HD1501the perfect companion to the HD1521 or SRM450v2, especially when using the high-pass outputs. A finely tuned, phase aligned and undeniably professional PA system is just a couple of patches away.

Ready for Anything
The phrase "would survive a nuclear explosion" is thrown around a lot these days, so we won’t do that here. But it goes without saying that the HD1501 embodies Mackie’s "Built-Like-A-Tank" philosophy and is certifiably road-worthy. First off, the enclosure is built using 15mm birch. Wood is not only more durable than plastic, but delivers a more natural sound. Hey, we were founded by hippies and dig that natural stuff. But, outward appearances do matter, so we’ve covered the HD1501 in durable textured black paint that minimizes the risk of scratching. The grill is equally robust, made using powder coated steel and flush with the enclosure to avoid denting. But we also thought of the install market and you can flip off that trademark "Mackie Blue" LED on the front if you want the HD1501 to blend seamlessly into the background. Throw in the fact that is one of the most compact subwoofers available and you’ve got an ultra-professional bass bin that can be tossed in the back of your sub-compact, bio-diesel electric hybrid (like I said…founded by hippies).
