Mackie TH18S
The Mackie TH-18s Powered Subwoofer has a ported bass reflex design that produces
tight low end. 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 its power and performance.
The TH-18s features Class-D Fast Recovery™ amplification, which is 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.
The TH-18s benefits from built-in Active electronics, like a precision crossover
and tuning filters for accurate bass response.
The TH18 is a great match for the TH15A as well as Mackie's SRMv2 Series and can
easily integrate into nearly any existing PA setup you may have. 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 top boxes. The integrated pole-cup can accommodate a standard mounting
pole.
The TH-18s offers class-leading power, has a high-output 18" woofer, and incorporates
features that make it lighter and more portable than the competition. Plus, it's
made with rigid plywood (not fiberboard) to handle the rigors of the road.
