This makes the sub extremely lightweight and portable, without compromising the power and performance that you need. It’s the first ever 18″ subwoofer specifically designed for use with the best-selling SRM450v2—add some serious low end to your portable PA with the SRM1801.

SHAKE, SHAKE, SHAKE THE ROOM

What does 1000W of peak power mean to you? It means having a subwoofer that delivers rump-shaking bass night after night. It means getting class-leading power and output. To accomplish this, the SRM1801 features Class-D Fast Recovery™ amplification. Class-D amps are more efficient and lightweight, with far less waste heat produced versus competing designs. Fast Recovery means you can occasionally push into clipping without a ton of nasty distortion. So, power is no problem… but how does it sound? The SRM1801 benefits from built-in Active electronics, like a precision crossover and tuning filters for accurate bass response. Some subwoofers have decent power, but when you listen, everything sounds loose and flabby. The SRM1801 delivers professional low end that you can feel…custom tuned to be tight and punchy.

SYSTEM FRIENDLY

Paired with a Mackie SRM450v2, you have a complete (and completely affordable) “plug and play” system that is ideal for small clubs, DJs or rehearsal spaces. The SRM1801 has both full-range and high-pass stereo outputs for connection to full-range top boxes. Just dial in the appropriate level and use the polarity switch to make sure the sub is in phase with the top boxes. The integrated pole-cup can accommodate a standard mounting pole, so your favorite speaker has a nice place to sit. Or you can just stack your full-range box right on top…the SRM1801 ain’t picky. It’s also a great match for the popular Mackie TH-15A and can easily integrate into nearly any existing PA setup you may have.
