Design & Build Quality of the QSC SC-1120
The QSC SC-1120 embodies QSC’s design philosophy: durability, efficiency, and acoustic precision. Constructed from high-strength birch plywood, its enclosure minimizes unwanted resonance and enhances tonal accuracy. The trapezoidal cabinet shape helps reduce standing waves, ensuring a smooth frequency response even in confined spaces.
Finished in matte black, the SC-1120 discreetly integrates behind perforated screens without causing light reflections. Its modular structure allows for easy installation and alignment. Despite its small size, the build quality matches QSC’s larger screen systems — ensuring years of consistent, reliable operation.
Every detail, from cabinet bracing to driver mounting, reflects QSC’s commitment to precision engineering and long-term performance stability.
Power Output & Performance
The QSC SC-1120 delivers powerful, detailed, and distortion-free sound. It features a 12-inch low-frequency driver combined with a 1.75-inch high-frequency compression driver mounted on a constant-directivity horn. This pairing ensures full-range coverage with smooth transitions between frequencies.
With a passive crossover network, the SC-1120 simplifies setup and minimizes amplifier requirements. It provides wide dispersion for even sound coverage across every seat — a critical factor for smaller theaters and private screening rooms.
Because of its efficient design and high sensitivity, the SC-1120 produces impressive output even with modest amplifier power. The result is rich, dynamic sound that immerses audiences in every scene — from subtle dialogue to high-impact action sequences.
