Design & Build Quality of the QSC SC-1150
The QSC SC-1150 showcases QSC’s engineering excellence in a durable, space-optimized design. Constructed from high-density birch plywood, the enclosure resists resonance and maintains tonal purity. The trapezoidal cabinet shape reduces internal reflections, improving clarity and projection.
A non-reflective black finish allows the SC-1150 to blend invisibly behind perforated screens, maintaining an authentic visual presentation. Moreover, its modular design simplifies setup, allowing installers to achieve perfect screen-to-speaker alignment quickly.
Every aspect of the build reflects QSC’s dedication to durability and reliability — two hallmarks that professionals worldwide trust for uninterrupted performance.
Power Output & Performance
Performance is where the QSC SC-1150 truly shines. This 2-way loudspeaker features a 15-inch low-frequency driver paired with a 1.75-inch compression driver on a precision-engineered HF horn. Together, they deliver a dynamic frequency response that covers the entire audible spectrum with accuracy.
Because of its passive crossover network, the SC-1150 simplifies system wiring while maintaining optimal phase and frequency alignment. Its high sensitivity ensures powerful sound output, even with lower amplifier power, making it energy-efficient and versatile.
In small to mid-sized cinema rooms, the SC-1150 produces crisp dialogue, impactful effects, and natural musical textures — bringing every scene to life with cinematic realism.
Advanced Technology & Features
The QSC SC-1150 integrates proprietary QSC acoustic technologies to achieve consistent tonal accuracy and balanced coverage. The custom waveguide design ensures even high-frequency dispersion, so every audience member hears detailed, lifelike sound regardless of seating position.
Additionally, the precision crossover design minimizes phase distortion, ensuring seamless transition between low and high-frequency drivers. This attention to acoustic detail helps the SC-1150 deliver smooth, fatigue-free listening, even during extended viewing sessions.
When paired with QSC DCA amplifiers or a Q-SYS system, performance can be fine-tuned using advanced DSP features like EQ, delay, and dynamic control — ensuring perfect integration within any cinema sound setup.
