Applications
Engineered for high-SPL and effective
low-end response (61 Hz @ - 10 dB), the
SM590i delivers consistent high-perfor-
mance music and paging for applications
requiring longer throw or higher volume
above the existing ambient noise level.
The SM590i is ideal for suface-mount
sound reinforcement/PA in applications
with high ambient noise levels including
casinos, warehouses, airports, transporta-
