SRM1801
Mackie SRM1801 powered subwoofers provide intense low-
frequency extension and punch to the Mackie SRM450v2
and other powered loudspeakers.
The SRM1801 powered subwoofer delivers 1000W peak
power via Class-D Fast Recovery™ amplification. The
Class-D amp design is ultra-efficient and, along with the
lightweight switch-mode power supply, drastically reduces
this subwoofer’s weight.
Premium circuitry includes built-in Active electronics, like
a precision crossover and tuning filters for accurate bass
response. Also included with the SRM1801 are user-friendly
features such as high-pass and full-range outputs for stereo
operation with a single sub. A polarity switch allows phase
alignment of the SRM1801 to the full-range loudspeakers.
A custom-designed transducer maximizes efficiency and
performance when matched with the system’s internal amp.
The 18-inch woofer uses a ferrite magnet with a 3-inch voice
coil.
The solid plywood enclosure features a ported bass
reflex design that produces tight low end. This makes
the sub extremely lightweight and portable, without
compromising power and performance. The integrated pole-
cup accommodates a standard mounting pole. Pair the
SRM1801 with the popular Mackie SRM450v2 or TH-15a
for an extremely powerful, portable and professional PA
solution.
