Product Description

The JBL 3730 Three-Way Bi-Amplified Passive ScreenArray Cinema Loudspeaker System provides smooth and accurate reproduction of cinema soundtracks in a compact and very cost effective system. The ScreenArray horn features a patented design that compensates for high frequency spreading caused by perforated screens for greatly improved audience coverage. JBL’s latest technical innovations are integrated into a system design that provides superior coverage, maximum power handling, and uniform acoustic power output, along with extremely low distortion. The ScreenArray design provides ideal power response and directivity control with seamless transitions between acoustic sections.
