Alto Pro TS108C Portable Column Array PA Speaker

The Alto Pro TS108C is a compact, all-in-one column array PA speaker from the professional-grade TrueSonic series. Combining an eight-inch subwoofer with a six-element 2.75-inch column array, a built-in three-channel digital mixer, and Bluetooth streaming into a single portable tower, it delivers powerful, room-filling sound with minimal setup - making it well suited to gigging musicians, DJs and venue operators who need high-performance audio in a small footprint.

The system delivers 600W peak power (300W RMS) via Class-D amplifiers, with 200W driving the low-frequency subwoofer and 100W powering the column array. The result is a maximum SPL of 123 dB at one metre, with a frequency response of 55 Hz to 15 kHz (-3 dB) and an ultra-wide 120° x 30° dispersion pattern that ensures even coverage across the room without the need for additional fills.

Mixer, DSP and Control

The onboard three-channel digital mixer features two balanced XLR and TRS combo inputs, each with two-band EQ and reverb, keeping source management straightforward without requiring an external mixer. Four instant DSP modes - Normal, Live, DJ and Custom - allow quick sonic adjustments to suit different applications, and precision DSP handles speaker protection throughout.

The Alto Pro App provides wireless mixer and speaker control from a phone or tablet, adding flexibility for operators who need to adjust levels remotely. A balanced XLR mix output allows the TS108C to be linked with a second speaker, and Bluetooth TWS (True Wireless Stereo) linking enables two units to be paired wirelessly for stereo operation.

Portability and Build

The injection-moulded ABS enclosure with metal grille and rubber feet is built for regular transport and long-term use. The subwoofer features a built-in top handle, and the column elements pack into an included shoulder bag for easy carrying between venues. The system assembles to a height of 1.86 metres and weighs 15.9kg in total.
