Alto Professional has announced two new column array PA speakers aimed at mobile DJs and performers – the TS108C (600W peak) and TS112C (1200W peak). Both systems include built-in mixers, reverb, Bluetooth streaming, and DSP modes, with the TS108C starting at $499.
Column array speakers have become increasingly popular with mobile DJs over the past few years, offering wider sound dispersion than traditional box speakers while taking up less vehicle space. Alto’s new TrueSonic models join a competitive market dominated by systems like the Bose L1 and Evolve series from Electro-Voice, though at notably lower price points.
The TS108C features an 8-inch subwoofer with six 2.75-inch drivers in the column array, delivering 300W RMS (600W peak). The larger TS112C steps up to a 12-inch sub with eight array drivers for 600W RMS (1200W peak). Both systems break down into sections for transport, with Alto including a shoulder bag for the column elements.
Built-in mixing and wireless control
What sets these apart from basic column speakers is the integrated mixing capability. The TS108C includes a three-channel mixer with dual combo inputs, while the TS112C offers five channels. Both provide two-band EQ per channel and built-in reverb – useful features for solo performers or small acts who want to minimise their set-up.
The systems can be controlled via Alto’s mobile app, allowing adjustments from anywhere in the venue. There’s also Bluetooth TWS (True Wireless Stereo) for linking two units wirelessly, though we’d need to test how reliably this works in real-world gigging situations, and there will be latency so it’s only good for playing background music, not actually DJing.

Four DSP modes are included for different applications – Alto claims these are “application specific”, though they haven’t detailed what these modes actually do. We’d expect the usual suspects: speech, live music, DJ/playback, and perhaps a flat response option.

What does “ultra-wide” mean?
Alto describes the 120° x 30° coverage as “ultra-wide”, but what does that mean, exactly? This horizontal dispersion should help fill wider spaces without the narrow “beaming” effect of traditional box speakers, though the vertical coverage remains fairly focused – likely to help reduce ceiling reflections in typical venues.
The frequency response looks reasonable for mobile DJ use, with the TS108C reaching down to 55Hz (-3dB) and the TS112C hitting 50Hz. Maximum SPL ratings are 123dB and 127dB respectively – plenty loud enough for most mobile gigs, though these figures are typically measured under ideal conditions.
First Thoughts
At $499 for the TS108C, Alto is clearly targeting price-conscious mobile DJs who want the benefits of column array design without the premium pricing of established brands. The built-in mixer and Bluetooth features tick the right boxes for wedding and event DJs who value quick set-up times.
The real question will be sound quality and reliability. While the specifications look decent on paper, column arrays are notoriously difficult to get right – the driver alignment and DSP processing need careful implementation to deliver the promised wide coverage without compromising clarity.
We’d be particularly interested to test the Bluetooth reliability and app control in busy RF environments, as these features can be hit-or-miss at packed events. The inclusion of balanced XLR outputs is sensible for daisy-chaining or feeding into larger systems.
Pricing and availability
The Alto Professional TS108C retails for $499 with the TS112C going for $799 each (UK and European pricing hasn’t been provided to us). Both systems are available now.
For mobile DJs considering column arrays, these join a growing field of options. The established Bose L1 Compact costs around $700, while the Evolve 30M from Electro-Voice sits at about $1300. At the budget end, you’ll find systems from Rockville and Harbinger, though build quality can be variable.
Whether Alto’s new offerings hit the sweet spot between price and performance remains to be seen – something that will become apparent once they move from “spec sheets” into actual DJ booths. For more information, head over to the Alto Professional website.
