Discrete and punchy – Portable and practical! 

A self-contained live sound solution for live performance. The hardest choice to make is….. ‘which model’?

‘Practicality’ was a key goal for the design team. To make an active system with features that make setups and break-downs easy. The column uses direct coupling to make connection fast. The column itself is also rotatable by +15% / -15% to ensure the output really covers the audience.
