The JBL 3677 cinema Loudspeaker system provides natural Sound quality for music and dialog in small cinema applications. The convenient allin- one enclosure requires no field assembly, simplifies set-up, and reduces labor costs. Enclosure design is extremely shallow in depth (292 mm; 11.5 inches), to minimize the space required behind the screen.
The high-Frequency section consists of the JBL 2416-1 pure titanium Compression driver and 2373 Flat-Front Bi-Radial® Horn. The titanium Diaphragm of the 2416-1 ensures natural Sound and reliability, mandatory in today’s motion picture theatres. The 2373 Horn provides smooth, even coverage throughout the auditorium.
The low Frequency driver is the JBL 2035H, which provides an exceptional match for system power handling and Frequency Response in the Crossover region.
The newly-designed Passive Crossover network is optimized to provide a seamless transition between driver components, for clear, articulate dialog, and high fidelity music reproduction. A protection circuit ensures that all components operate within their optimal power handling range, to ensure many years of high reliability performance.
