The Thump12A pumps out a massive amount of sound for its size. Its high-output woofer generates ample quantities of throbbing bass, and its 1.4" titanium dome driver ensures even, wide dispersion. Ultra-efficient Class-D amplification with Mackie's proprietary Dynamic Bass Response pushes plenty of power to the high-frequency compression driver and high-output woofer. And you don't need to worry about damaging your speaker, thanks to the Thump12A's next-generation system protection and thermal limiting.Connecting your gear to the Thump12A is a piece of cake — its built-in two-channel mixer features Vita preamps with Wide-Z technology, so they accommodate microphone, line-level, and instrument signals. An XLR thru output makes for effortless wired connection to other Thump speakers, while flexible mounting options allow tripod- and pole-mounting, as well as stage monitor use.
