The Alto TS315 is a powerful 15″ powered PA speaker designed from the ground up for performance and reliability. The no-compromise design includes all new transducers, amplifier modules, and custom tuning means you get the loudest and clearest sound possible. Another feature is the all-new low-frequency drivers, designed to play louder and handle more power than their already-impressive predecessors, the wildly-successful TS2 Series. They also have a new horn-loaded high-frequency driver. This impressive transducer has a brand-new heat sink design that provides exceptional heat dissipation for impressive power-handling, even at all-night-long concert levels. Because these new drivers can safely handle the additional power, the TS3’s take full advantage of the increased wattage and will play at higher SPLs with lower distortion making them perfect for any band, venue or DJ.
