The Mackie HD1521 2-Way High-Definition Powered Loudspeaker delivers 1600W of peak system power via Class-D Fast Recovery amplification. Class-D amp design delivers up to 95% efficiency and, along with the lightweight switch-mode power supply, drastically reduces loudspeaker weight.

Mackie High-Definition Audio Processing provides unmatched sonic accuracy and clarity. Mackie Active technology includes a precision 2-way crossover, transducer time alignment, and phase correction. Plus, patented acoustic correction algorithms harness the power of proprietary measurement tools that identify sonic anomalies that are inherent to all horn-loaded systems. Extremely complex algorithms are then applied to the HD1521 to counter these anomalies, elevating the experience of both the audience and engineer.

EAW custom-designed HD Series transducers maximize efficiency and performance when matched with the system's internal amps. The 15-inch woofer uses a neodymium magnet for reduced weight, and the 3-inch voice coil dissipates heat extremely well. The 1.75-inch compression driver utilizes heat-treated titanium, which provides increased diaphragm rigidity, eliminating distortion that can occur due to surface inconsistencies.

The integrated 3-band contour EQ with a sweepable mid allows the user to custom-tailor system tone for the application or correct for common room anomalies. A bypass switch provides easy implementation of a pre-set EQ.
