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 RecoveryTM 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.
