Alto Professional TS408 Active Loudspeaker

Alto Professional TS408 Active Loudspeaker

The Alto Professional TS408 is a compact yet extremely powerful active loudspeaker with an 8-inch woofer. This model is ideal for mobile performers, DJs, and event hosts who are looking for maximum portability (weighing only 9.4 kg) without sacrificing sound quality. The Class D amplifier provides 2000 W (Peak) power and 130 dB sound pressure.

Like larger models in the series, the TS408 supports control via the free “Alto App” (iOS/Android). In the app, you can control Bluetooth audio, change "Speaker Use" modes, create your own EQ settings, and manage True Wireless Stereo (TWS) pairing. The integrated 3-channel mixer allows you to connect microphones, instruments, or a line-level signal directly to the speaker.

The speaker's design is versatile: it can be mounted on a stand, used as a stage monitor ("wedge"), or hung using the integrated M6 mounting points.
