Alto Professional TS412 2-Way 12-Inch Powered Loudspeaker with Bluetooth and DSP Control

The Alto Professional TS412 delivers 1,250 W RMS (2,500 W peak) of Class-D amplification through a 12″ low-frequency driver and a 1″ ceramic high-frequency compression driver. Its built-in 3-channel mixer and DSP presets allow on-board EQ and signal routing, while Bluetooth® streaming and True Wireless Stereo linking via the Alto App add modern connectivity for live-sound and DJ applications.

Encased in a rugged polypropylene enclosure with integrated handle and steel grille, the TS412 is engineered for portability and durability. Pole-mountable, wedge-positionable, or suspension-capable, it adapts to stage-monitor, main-PA, or installation roles. Advanced DSP offers contour EQ, limiter, and delay settings accessible remotely via Alto’s free iOS/Android app.
