Meyer Sound Acheron 100 Screen Channel Loudspeaker for Cinema Applications with 3-Pin XLR
At the heart of Meyer Sound’s EXP line of cinema products is the Acheron high-performance screen channel loudspeaker. Optimized for installation behind perforated screens, the two-way loudspeaker combines the advantages of self-powered technology and innovative horn design to deliver exceptional, precise coverage for the left, right, and center sound channels of cinema.
Features:
- Small footprint and narrow width are ideal for small venues or fill applications
- Amazing power-to-size ratio
- Exceptional linearity and transient reproduction at any level, high peak power output, and extremely low distortion
- Self-powered to simplify setup and increase reliability
- Flexible rigging for flown and ground-stacked arrays
- Integrates easily with Meyer Sound’s 750-LFC, 900-LFC, and LEOPARD loudspeakers
