[. . . ] 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-4215 dual 15" (381mm) low-frequency enclosure is designed specifically to address the extended low-frequency response required for cinema applications. The LF-4215 covers the frequency range from 35 Hz to 1000 Hz, depending upon the high-frequency system requirements. Close Coupled Woofers (CCW), with their tight spacing between woofers, improves coupling and keeps coverage angles wide over a greater frequency range than more widely spaced designs. The HF-75 components come pre-assembled to reduce field assembly time.
