The STM series (scale through modularity) loudspeaker cabinets are appropriate for touring, festivals, and sound company rental. The new system combines the NEXO Alpha functionality with the technical innovation of NEXO GEO waveguide designs, and delivers a powerful, flexible, and easy to use system. STM enables line array systems to scale up or down depending on event audience size, from 1,000 to 100,000 people.
