Meeting cinema requirements for extended low-frequency response differentiates the LF-4215-8F from more conventional “rock-and-roll” woofer systems. The LF-4215-8F covers the frequency range from 35 Hertz to 1000 Hertz, depending upon the high-frequency system requirements. The LF-4215-8F is an 8 ohm version of the standard 4 ohm LF-4215 that is designed for safe and easy suspension via M10 fly points.
- Page 11 Ensure all attachment points are installed and correctly tightened in order to maintain enclosure’s rated strength. Additionally, air leaks resulting from missing hardware will degrade the loudspeaker’s performance. Use only QSC’s M10 forged shoulder eye bolts.
