Mackie HD1801

The Mackie HD1801 18-inch powered subwoofer provides intense low-frequency extension and punch to any Mackie full-range system. The HD1801 High-Definition Powered Subwoofer 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 this subwoofer’s weight.

EAW custom-designed HD Series transducers maximize efficiency and performance when matched with the system’s internal amp. The 18-inch woofer uses a ferrite magnet with a 4-inch voice coil.

Premium circuitry includes a symmetrical Linkwitz-Riley crossover, precision tuning filters and user-friendly features such as high pass outputs for stereo operation with a single sub. The lightweight and portable 15mm birch plywood enclosures feature a ported, direct-radiating design. It is rugged and ready for install using the 12 integral fly points. Standard M10 eyebolts allow the HD1801 to be flown both vertically and horizontally.

The professional look of the HD1801 may be further enhanced by defeating the front panel LED. The integrated pole-cup accommodates a standard mounting pole. Pair the HD1801 with any Mackie HD-Series full-range loudspeaker for an extremely powerful and fully high-definition PA solution.
