Alto Professional began a live sound revolution with the top-selling Truesonic loudspeaker series. Now, Alto Professional has refined those same innovative technologies to create the remarkable TX Series. The TX Series loudspeakers were designed to the same performance standards as our award-winning TRUESONIC series—with quality components and accurate, transparent sound—but at a more affordable price.

Big Sound, Portable Package


Experience power, performance, and portability. TX12 comes equipped with efficient, bi-amped Class D amplification that pumps out a generous 600 Watts of peak power. An exacting electronic crossover ensures smooth frequency response from the 12” low-frequency driver and 1” high-frequency compression driver. Bass porting offers extended low-end response, while the steel grille adds extra protection.

Ready for Anything


Built to travel, the road-ready TX Series is both lightweight and portable. Trapezoid cabinet contouring makes either upright or wedge-monitor placement a snap. A pole-mount socket and a comfortable handle are conveniently built in. Create a custom setup using the Link output to chain multiple cabinets together. For the musician, DJ, or live-sound provider craving professional audio reproduction, The TX Series delivers impressive, dynamic sound night after night.
