The brand new SRM1801 active 1000w sub woofer from Mackie brings low end thump to any PA system.

Designed to perfectly accompany Mackies SRM speaker range, the SRM1801 incorporates a ported bass reflex design that produces tight low end rather than floppy loose low end that is apparant in some other subs.

The SRM1801 is lightweight and easily portable due to its Class D, lightweight, fast recovery 1000 watt amp, meaning that you can occasionally push into clipping without a ton of nasty distortion.

The SRM1801 18 inch sub can be used to add well needed low end to any PA set-up whether you´re using SRM450´s, SRM350´s, TH15-A´s or any other PA speakers via its full-range and high-pass stereo outputs. Speakers can be pole mounted to the SRM1801 or simply stacked on top.
