Mackie HD1501

The HD1501 and HD1801 subs are said to "offer many of the same benefits as the full-range models, including Class-D Fast-Recovery amplifier technology, delivering up to 1600W of peak power, as well as efficient, cool running, switch-mode power supplies."

With custom transducer design and system tuning by EAW, HD subs are designed to provide “unparalleled low-end extension, ” according to Mackie.

The HD1501 and HD1801 have 15-inch and 18-inch high-output woofers respectively, as well as Mackie’s Active processing. The HD1801 18-inch subwoofer is ideal for use with either the HD1521 or HD1531, according to the company and the HD1501 15-inch sub is perfect for systems using SRM450v2 Active Loudspeakers (or SRM350v2s), they say.
