The CS300MH is a passive, mid/hi, screen channel cinema speaker module for commercial cinema applications. Coupled with 1 to 2 (CSB215) low frequency modules, it is perfect for auditoriums of 250-450 seats. The high frequency section features a high performance PRD1000 planar ribbon transducer designed and manufactured by SLS Audio. The unique design and properties of the planar ribbon driver delivers fast transient accuracy as well as an exceptionally smooth high- frequency response delivering a more direct sound to the audience even with screen spreading. The midrange section uses two hi-efficiency mid-range 8” drivers. This provides for an open and clear sound despite loud listening levels.
