SC-2150
Cinema Loudspeaker System
Features
•Optimized design for smaller cinemas - up to 55 ft (16.6 m) in length
•
•Heavily braced, MDF
•6.5" horn loaded midrange driver provides highly articulate dialogue
•Shallow 14.5" (368 mm) depth reduces space required behind the screen
•Advanced crossover circuitry protects the HF and MF drivers from over- powering and excessive
Developed specifically for the unique requirements of professional motion picture playback in smaller cinemas, QSC extends its commitment to the cinema market with the introduction of the

The dual 15" (381 mm)
With Symmetrical Port Loading (SPL), bass ports are evenly spaced on each side of the transducers, making internal pressure more uniform across the back surface of the transducer. This prevents the cone from being displaced to one side or another by unbalanced forces, reducing the chance of driving the voice coil out of the center of the gap at high power.
