Alto Professional TS415 Active Loudspeaker

Alto Professional TS415 Active Loudspeaker

The Alto Professional TS415 is the most powerful and largest model in the popular TS4 series. The device generates a massive 2500 W (Peak) power and achieves a maximum sound pressure of 135 dB. Thanks to its large 15-inch low-frequency driver, this loudspeaker reproduces low frequencies down to 33 Hz, making it capable of operating alone in most cases (for parties, DJ performances) without a separate subwoofer.

The loudspeaker features smart control via the free "Alto App" (Android/iOS). In it, you can control Bluetooth audio, change "Speaker Use" modes (Live, DJ, Speech, etc.), create your custom EQ settings, and even remotely configure True Wireless Stereo (TWS) pairing. The integrated 3-channel mixer allows direct connection of microphones, instruments, or a line signal.

Despite its size and power, the TS415 weighs only 17.2 kg, and ergonomic handles facilitate transport. The loudspeaker's design allows it to be used on a stand, as a floor monitor, or hung in permanent installations (M10 points).
