PRODUCT OVERVIEW

The?Mackie SRM1850 18″ Powered Subwoofer?is designed to extend the low-frequencies of sound systems and is well suited for various sound reinforcement applications including portable DJ’s, live stage, houses of worship, theater, rehearsals, and more. The integrated Class-D amplifier drives 1600W of power to the 18″ woofer, which provides a frequency response of 40 to 120 Hz with a max SPL of 132 dB. The tour-grade poplar plywood enclosure is front ported and internally braced to deliver maximum low-frequency extension and punch.

The SRM1850 subwoofer features stereo XLR inputs (L/R) and two full-range outputs as well as two high-pass outputs. The integrated variable digital crossover includes presets for the optional SRM550 and SRM650 full-range loudspeakers. The built-in Smart Protect DSP protects the subwoofer from overloads, while a compression circuit prevents damaging transient peaks while remaining transparent under normal operating conditions. The Mackie SRM1850 ships with a power cord.
