The SL412i is a 3-way high output,active-driven, wide dispersion loudspeaker module. It is designed as part of a sound reinforcement speaker system that includes the SL3000 system control and amplification system. The SL412 Loudspeaker system benefits from being designed exclusively to operate above 60 Hz. By optimizing the ideal operating band pass of each system component, the SL412i can achieve extremely high output levels consistently and safely.The SL412i is exact identical performance and finish units of the existing SL412, except they do not incorporate the fixed handles for touring and presentation use. The ‘I’ version is designated for fixed installation use with the same existing mounting and flyware fixings.
