The HD1521 2-Way High-Definition Powered Loudspeaker delivers class-leading power, unmatched clarity and extreme flexibility in a design that is understated, yet stunning.
Class-D Fast Recovery' amplification produces a ridiculous 1600W of peak system power. High-Definition Audio Processing incorporates next-generation Mackie "Active" electronics and re-defines powered loudspeakers by implementing Mackie's patented acoustic correction processing for an experience that is unrivaled in the world of portable powered PA systems. System tuning and custom transducer design by EAW ensures an optimized system that sounds great every time. The compact yet rugged, all-wood enclosure offers superior protection and a clean, unimposing look that will blend seamlessly into almost any environment. HD1521 2-Way High-Definition Powered Loudspeaker Elevate Your Experience.The HD1521 incorporates the latest in Class-D amplifier technology to deliver a chest-pounding 1600W of peak system power. Both internal amps are designed using Mackie's legendary Fast Recovery' circuitry. Other amplifiers can "latch" when pushed to clipping, leading to distorted audio, but Fast Recovery' amplification reacts instantly to the occasional aggressive transient, drastically reducing the time it takes for the amp to recover, ensuring clean audio under the most demanding of situations. This potent bi-amplified system is the highest powered 2-way available in its class, providing a beefy 700W RMS low-frequency amplifier and a 100W RMS high-frequency amplifier that, when combined, can deliver a max SPL up to 135dB (calculated, measured maximum SPL of 125dB). There is a lot of debate regarding SPL measurements, and what you see on paper doesn't always tell the whole story. To forever eliminate confusion and prove that Mackie is dedicated to providing real, testable specs, we have worked up a handy (and somewhat nerdy) guide to the shady world of SPL measurements: Will the Real Maximum SPL Please Stand Up?Measurements and calculators aside, it only takes one listen to know that the HD1521 delivers more bang for your buck that any other portable 2-way loudspeaker out there.FEATURES:* 1600W of ultra-efficient Class-D Fast Recovery' amplification LF 700W RMS / 1400W peak HF 100W RMS / 200W peak * High-definition audio processing: Revolutionary patented acoustic correction Transducer time alignment and phase correction Precision 2-way crossover * Custom designed transducers by EAW 15" neodymium woofer with 3" voice coil 1.75" compression driver with heat-treated titanium diaphragm * User-adjustable 3-band contour EQ with sweepable mid-frequency * Ultra-compact and lightweight (80lbs) * Integrated limiting and protection circuitry * Rugged all wood cabinet (15mm birch plywood) * 12 integrated fly points for horizontal and vertical rigging * Stand / pole mountable
