Mackie THUMP M-TH18SA 1000w 18" Powered Subwoofer

The Mackie TH-18s powered subwoofer speaker delivers powerful, chest-thumping lows that instantly bring massive Thump to any Mackie PA system. Designed by the same team that produced the SRM450v2, 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 Mackie subwoofer extremely lightweight and portable, without compromising the power and performance that you need—at a price point that doesn't kill your budget.

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 TH-18s features Class-D Fast Recovery amplification. Class-D amps are more efficient and lightweight, with far less waste heat produced. Fast Recovery means you can occasionally push into clipping without a ton of nasty distortion.

The TH-18s' sound benefits from built-in Mackie Active electronics, like a precision crossover and tuning filters for accurate bass response. This helps the Mackie subwoofer deliver professional low end that you can feel, custom tuned to be tight and punchy.

System Friendly
Paired with a Mackie TH-15A, you have a complete (and completely affordable) plug-and-play system that is ideal for small clubs, DJs, or rehearsal spaces. The Thump subwoofer speaker is also a great match for the popular Mackie SRMv2 Series and can easily integrate into nearly any existing PA setup you may have. The TH-18 speaker 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. If you prefer you can also stack your full-range box right on top of this sturdy Mackie speaker.

Value Loaded
The Mackie TH-18 subwoofer gives you what you need without decimating your budget. For its price range, the TH-18 powered subwoofer offers an exceptional amount of power, has a high-output 18" woofer that can be felt from across the room, incorporates features that make it lighter and more portable, and it's made with rigid plywood (not fiberboard) to handle the rigors of the road.
