Alto Professional TS415 15-Inch Peak Powered Loudspeaker with Bluetooth, DSP, and App Control

The Alto TS415 delivers a massive 2,500 W peak (1,600 W LF + 900 W HF) of Class-D power through a 15″ low-frequency driver and 1″ ceramic compression driver. Its onboard 3-channel mixer (two XLR-¼″ combo inputs + Bluetooth® channel) with dedicated level controls and XLR mix output provides seamless connectivity for live sound, DJ rigs, or presentations. True Wireless Stereo linking and full DSP control via the free Alto App enable custom EQ, limiter, delay, and speaker-use presets for ultimate tonal flexibility.

Built to withstand the road, the TS415’s rugged polypropylene enclosure with integrated suspension points and pole socket can be pole-mounted, used as a floor monitor, or flown. A durable steel grille protects the components while the compact form factor and lightweight design make transport and setup effortless.
