[. . . ] Power limiter circuitry protects the driver from overpowering and a response correction filter smoothes the frequency response of the horn/driver combination. The driver and equalization network provides for more reliable operation, ensuring the show will go on. The LF-3115 15" (381mm) low-frequency enclosure is designed specifically to address the extended lowfrequency response required for cinema applications. The LF-3115 covers the frequency range from 35 Hz to 1000 Hz, depending upon the highfrequency system requirements. The SC-312X is designed for ease of installation. The HF-63X1 components come pre-assembled to reduce field assembly time. Three bolts are all that are required to secure the HF-63X1 to the top of the LF-3115 enclosure.
