The Mackie ThumpSub GO is a portable battery-powered subwoofer designed to deliver powerful low-frequency reinforcement for mobile DJs, musicians, live performers, outdoor events, and portable PA systems. Equipped with two custom 8-inch woofers and a 400W peak Class-D amplifier, this compact subwoofer produces up to 123 dB peak SPL with a frequency response extending down to 32 Hz (-10 dB). Its dual hot-swappable battery compartments provide up to 6 hours of operation with the included GB-200 lithium-ion battery or up to 12 hours with an optional second battery. Built-in Bluetooth 5.4 audio streaming, dual XLR/TRS inputs, balanced XLR outputs, selectable output modes, and phase adjustment make the ThumpSub GO a flexible bass solution for professional sound systems operating with or without access to AC power.
The Mackie ThumpSub GO brings dedicated low-frequency reinforcement to portable sound systems without requiring constant access to electrical power. Designed for mobile DJs, singer-songwriters, small live performances, outdoor gatherings, and compact PA applications, it features two custom 8-inch low-frequency drivers powered by an integrated 400W peak Class-D amplifier. The system delivers up to 123 dB peak SPL with a frequency response of 39 Hz to 100 Hz (-3 dB) and an extended frequency range of 32 Hz to 152 Hz (-10 dB). This additional low-frequency output helps complement smaller powered loudspeakers that may not reproduce deep bass as effectively on their own. The compact design makes it a practical choice for portable music systems, karaoke events, presentations, and live entertainment where transportation and setup convenience are important.
One of the ThumpSub GO's defining features is its rechargeable battery system. Two battery compartments support Mackie GB-200 lithium-ion battery packs, with one battery included to provide up to 6 hours of operation. Installing a separately available second battery increases total operating time to as much as 12 hours, making the system suitable for longer events and extended performances. The hot-swappable design allows one battery to be replaced without interrupting audio playback when another charged battery is installed and supplying power. Each GB-200 battery features an 8880 mAh capacity and an 11.1V nominal rating, with an approximate charging time of three hours under supported conditions. The subwoofer can also operate from standard 100-240V AC power, allowing users to switch between battery-powered portability and conventional electrical operation depending on the venue.
Flexible audio connectivity makes the ThumpSub GO easy to integrate into portable PA systems. Two balanced XLR/1/4-inch TRS combination inputs accommodate compatible wired audio sources, while two balanced XLR outputs provide connections for powered loudspeakers and additional equipment. The output mode switch allows operators to select stereo or mono routing, and the high-pass mode switch provides full-range or filtered output signals for connected speakers. A phase inversion switch allows adjustment between normal and inverted polarity to help optimize bass integration. Bluetooth 5.4 streaming adds wireless playback from compatible smartphones, tablets, and other Bluetooth audio devices, with streamed audio also available through the connected speaker system. These features allow the subwoofer to serve as a low-frequency extension and audio connection point for compact portable sound setups.
The ThumpSub GO is optimized for pairing with the Mackie Thump GO battery-powered loudspeaker and can also complement other suitable portable powered speakers, particularly models with woofers measuring up to 10 inches. Its slim enclosure supports both horizontal and vertical positioning, allowing the subwoofer to fit beneath tables, beside portable DJ booths, or into narrow performance spaces. An ergonomic carrying handle provides convenient transportation, while the integrated M20 threaded pole receptacle accepts the separately available Mackie SPM400 speaker pole for mounting a compatible loudspeaker above the subwoofer. A front LED on/off switch, Bluetooth status indicator, battery status LEDs, and signal/overload indicators provide convenient visual monitoring. Integrated peak and RMS limiting and thermal protection help protect the amplifier and power supply during demanding use.
Built for portable sound reinforcement, the ThumpSub GO combines efficient Class-D amplification, rechargeable battery operation, and flexible speaker connectivity in an easy-to-transport design. Its 40 lb (18.1 kg) cabinet weight without a battery increases to approximately 41.7 lb (18.9 kg) with one GB-200 battery installed. The integrated handle and horizontal or vertical positioning options make it convenient for mobile entertainers who frequently transport equipment between venues. Whether used for small outdoor DJ events, live acoustic performances, karaoke, parties, presentations, or battery-powered PA systems, the ThumpSub GO provides additional bass output without the complexity of a conventional mains-powered subwoofer installation.
