APPLICATION

The SP425 was designed for distributed systems, the 13° per side trapezoid angles match the 90° horizontal coverage pattern allowing the creation of tight packed clusters.
The pole mount cup and balance-optimized handles allow for quick and easy load-in for portable use.
Its high output capabilities let it act as a main system for smaller concert or portable A/V events or even provide front or side fill for concert touring applications. The comprehensive system mounting points permit safe suspension in permanent installations.
