Designed not only to deliver, but to thrive on today's pushed-to-the-max soundtracks, QSC low-frequency components bring out the full richness of screen channel sound. Unlike re-purposed rock and roll PA cabinets, our LF components are built from the ground up with cinema-specific details that speed up installation. For example, offset terminal cups and pre-installed rubber feet. We also enhance performance with smart design by using tight driver spacing in our multi-driver boxes to improve coupling and widen coverage angles. LF components are the foundation of full, clear screen channel sound, and nobody builds better screen channel enclosures than QSC.
