JBL 4675C-8LF Cinema Loudspeaker System, 34Hz to 20kHz Frequency Range,

The JBL 4675C-8LF provides powerful, smooth and accurate reproduction of motion picture soundtracks in medium and large cinemas. The system is comprised of two parts: the 4675C-HF high frequency pack and either the 4648A-8 (8 ohm) or 4648A-4 (4 ohm) low frequency system. The 4675C-HF high frequency pack features the JBL 2446H, 100 mm (4") diaphragm compression driver, JBL 2360A Bi-Radial horn and JBL 2506B fully adjustable bracket.

The large format Bi-Radial horn ensures uniform dispersion of the high frequency information throughout both the vertical and horizontal coverage angles. The JBL 4648A-8 offers the highest output power available in a cinema screen loudspeaker system.

The low frequency system employs JBL's patented Vented Gap Cooling 2226J 380 mm (15") transducers providing high power handling with extremely low power compression providing the highest acoustic power output possible. The transducers feature 100 mm (4") voice coils operating in a large symmetrical field geometry (SFG) magnet structure reducing second harmonic distortion.
