Alto Professional TX412B Active Loudspeaker

Alto Professional TX412B Battery-Powered Active Loudspeaker

ALTO TX412B is a powerful and versatile portable loudspeaker designed for performers, event hosts, and musicians who need high-quality sound in locations without power outlets. The device features an integrated battery that provides up to 10 hours of operation, making it perfect for outdoor events or street performances.

The loudspeaker boasts 600 W (Peak) power, generated by an efficient Class D amplifier, driving a 12-inch woofer and a 1-inch high-frequency compression driver (with a titanium diaphragm). This combination, along with a wide dispersion angle (90° x 60°) horn, ensures clear and consistent sound coverage.

One of the most important features is Bluetooth connectivity, allowing wireless music streaming from a phone or tablet. Additionally, the TWS (True Wireless Stereo) function enables two TX412B speakers to be wirelessly connected into a single stereo system. The device also includes an integrated 2-channel mixer (for microphone, line signal, and Bluetooth) and a "Contour" switch, which enhances low and high frequencies for music playback.
