It operates over a nominal bandwidth of 29 Hz to 60 Hz and is optimized for use with L-Acoustics amplified controllers, leveraging advanced DSP for system alignment, protection, and cardioid deployment. The enclosure uses a bass-reflex design with high-excursion drivers to deliver substantial SPL with controlled directivity when configured in directional arrays.
