The Mackie HD1521 2-way high-definition powered loudspeaker delivers class-leading power, clarity, and flexibility in a design that is stunning yet understated. This Mackie loudspeaker's 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 intense experience. 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.
Maximize Your Output
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). Measurements and calculators aside, it only takes one listen to know that the HD1521 delivers massive bang for your buck.
EAW Inside
The HD1521 is a perfectly tuned system that is truly greater than the sum of its parts. This is only possible due to the hard work and insane genius of the engineering team over at Eastern Acoustic Works (EAW). Not only did they fine-tune the system for complete optimization, they also custom-designed the transducers, ensuring maximum efficiency and performance.
The high-end 15" neodymium woofer features a 3" voice coil and is built to handle the massive power delivered by the low-frequency amplifier. The magnet is made using neodymium, which provides a greater magnetic field with far less material. This makes the woofer extremely lightweight without sacrificing one bit of performance. And the large 3" voice-coil is built to handle and dissipate far more heat than traditional designs.
The 1-3/4" compression driver brilliantly reproduces high frequencies with a diaphragm made using heat-treated titanium. Heat-treating increases the rigidity of the diaphragm, eliminating nasty distortion that can occur due to inconsistencies on its surface. It also greatly increases the life of the driver, so you can count on stunning high-frequency production for years.
