Mackie ThumpSub GO 8" 400W Portable Battery-Powered Subwoofer

Mackie ThumpSub GO Battery-Powered Portable Subwoofer with Bluetooth
You might think your battery-powered PA system sounds good on its own. But deep down, you know it's missing a little more oomph. You want that chest-thumping low end that shakes the dance floor. Now, that's possible with the ThumpSub GO battery-powered portable subwoofer.Up to 12 Hours Total Battery LifeThumpSub GO combines two battery compartments for up to 12 hours of continuous bass thumping. Since the sub works perfectly with a single battery, it's also possible to charge a second battery elsewhere, then hot swap it out-without the unit powering down for even a moment!
Note: ThumpSub GO includes one GB-200 battery for up to 6 hours of battery life. Optional second battery sold separately.
Easy to Carry
Carry the bass like a briefcase with the built-in ergonomic handle, making ThumpSub GO the ultimate portable subwoofer for mobile DJs and performers.Horizontal
ThumpSub GO works equally well vertically, making it easy to fit into narrow spaces where it won't get in the way. Subwoofers should be felt, not seen.Effortless Integration with Your PA System
Connect Portable Loudspeakers
Connect portable loudspeakers for a complete mono, stereo or zone PA system, reinforced with deep, floor-shaking bass.
Note: Recommended for loudspeakers with up to a 10" woofer size.

Give Your Speakers Bluetooth
Connect to ThumpSub GO via Bluetooth to stream wirelessly through the whole system, including any connected loudspeakers, even if the speakers don't have Bluetooth!
Minimize Footprint with Pole Mount
Mount a speaker above ThumpSub GO with the SPM400 speaker pole (sold separately) for an all-in-one PA system with clear sound, powerful bass and a smaller footprint.

Phase Inversion SwitchPlace ThumpSub GO and your speakers wherever is most convenient, and if you have any issues with phase cancellation, use the phase inversion switch.High Pass and Full Range Modes
High Pass and Full Range modes change the balance between the subwoofer and connected loudspeakers. Try both modes and see which sounds ideal for the situation.
All of the Lights
Keep track of ThumpSub GO when the lights go down with useful LEDs for system power, overload, and one for each battery. You'll know the status in a glance.
Optimized for Thump GO
ThumpSub GO is optimized to work seamlessly with the Thump GO battery-powered loudspeaker. It's also great for adding low-frequency extension to the Mackie ShowBox all-in-one performance rig, or any portable powered loudspeaker from any brand.
