The HD1521 2-Way High-Definition Powered Loudspeakerdelivers 1600W of peak system power via Class-D FastRecovery™ amplification. Class-D amp design delivers up to95% efficiency and, along with the lightweight switch-modepower supply, drastically reduces loudspeaker weight.

Mackie High-Definition Audio Processing providesunmatched sonic accuracy and clarity. Mackie Activetechnology includes a precision 2-way crossover, transducertime alignment, and phase correction. Plus, patentedacoustic correction algorithms harness the power ofproprietary measurement tools that identify sonic anomaliesthat are inherent to all horn-loaded systems. Extremelycomplex algorithms are then applied to the HD1521 tocounter these anomalies, elevating the experience of boththe audience and engineer.

EAW custom-designed HD Series transducers maximizeefficiency and performance when matched with the system'sinternal amps. The 15-inch woofer uses a neodymiummagnet for reduced weight, and the 3-inch voice coildissipates heat extremely well. The 1.75-inch compressiondriver utilizes heat-treated titanium, which providesincreased diaphragm rigidity, eliminating distortion that canoccur due to surface inconsistencies.

The integrated 3-band contour EQ with a sweepable midallows the user to custom-tailor system tone for theirapplication or correct for common room anomalies. A bypassswitch provides easy implementation of a pre-set EQ.

The 15mm birch plywood enclosure is rugged and readyfor install using the 12 integral fly points. Standard M-10eyebolts allow the HD1521 to be flown both vertically andhorizontally, and its 80 degree x 50 degree horn can be rotated 90° ifdesired. The look of the HD1521 is understated and the frontLED can be defeated for maximum stealth. The lightweightdesign of the HD1521 allows for pole-mounting on a tripodstand or atop a subwoofer.
