Introduction
The Mackie TH-12A Powered Loudspeaker delivers a chest-pounding 400W of peak system power via ultra- efficient Class-D amplification. This means more power with less weight, perfect when portability matters. The 12" high-precision woofer and 1" compression driver provide punchy sound with superior midrange response, ideal for vocal and acoustic applications.
An integrated 3-band contour EQ with a sweepable mid-frequency lets you dial in the perfect tone and even allows you to correct common room anomalies. The XLR input handles both mic and line level signals, so you can just hook up a mic and be heard, assuming you have something to say. There’s even an XLR Thru that allows you to easily “daisy chain” multiple TH-12As for increased coverage.
The TH-12A harnesses Mackie’s Active technology, including transducer time alignment, phase correction and precision crossovers, maximizing the potential of every component. The TH-12A is truly greater than the sum of its parts.
Convenient top and side handles are integrated into the rugged, impact-resistant polypropylene enclosure, providing a PA solution that is as durable as it is portable. It makes the perfect stage monitor, and at only 25.5 lb, it’s a breeze to pole-mount on a tripod stand or atop a subwoofer.
