Introduction
Thank you for choosing the Mackie Thump TH-18s subwoofer. Mackie’s Thump Series powered loudspeakers
achieve the perfect balance of power, portability, and most importantly, value. Designed by the same team that
produced the best-selling Mackie SRM450v2, Thump Series loudspeakers deliver real power in a design that is
extremely lightweight and portable. The TH-18s incorporates Mackie-standard professional components like
efficient Class-D Fast Recovery™ amplifiers and system-optimizing Active electronics so that everything sounds
great right out of the box.
The TH-18s has a ported bass reflex design that produces tight low end. And the lightweight, ultra-efficient
Class-D Fast Recovery™ power amplifier delivers 1000W peak power with less risk of thermal overload. This makes
the sub extremely lightweight and portable without compromising the power and performance that you deserve.
Pair this power with our proven built-in Active electronics, including a precision crossover and tuning filters, and
you get professional low end that you can feel...custom tuned to be tight and punchy.
Paired with a Mackie TH-15A or the popular SRM450v2, you have a complete (and completely affordable) “plug
and play” system that is ideal for small clubs, DJs and rehearsal spaces. The TH-18s 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 loudspeakers. 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 of the sub...the TH-18s ain’t picky.
So if you are looking for an extremely powerful, affordable PA setup that is simple to use, then you’re in the right
place.

™ amplification
