The QSC RSC-112 defines a new benchmark in professional cinema and studio monitoring. This 3-way screen channel loudspeaker with tri-amp configuration is purpose-engineered to deliver pristine audio clarity, seamless coverage, and unmatched tonal balance. Whether used in professional screening rooms, luxury home theaters, or post-production suites, it reproduces every detail with precision.
Built as part of QSC’s Reference Monitor System, the RSC-112 combines innovation, craftsmanship, and acoustic intelligence to deliver reference-level audio for immersive cinematic experiences.
Design & Build Quality of the QSC RSC-112
Crafted for long-term durability and acoustic accuracy, the QSC RSC-112 features a 15-ply Baltic birch plywood cabinet for superior strength and minimal resonance. Its 90° axisymmetric horn ensures even horizontal and vertical dispersion, ideal for behind-screen installations.
The compact enclosure design simplifies placement while maintaining a wide frequency response and high output capability. Moreover, QSC’s Directivity Matched Transition™ (DMT™) technology aligns the dispersion of the woofer and horn, ensuring uniform sound coverage across the audience area. The result is consistent tonal balance and excellent speech intelligibility from every seat.
Power Output & Performance
The QSC RSC-112 features a 12-inch low-frequency transducer paired with a coaxial mid-/high-frequency compression driver that integrates a 3.5-inch midrange diaphragm and a 1.75-inch high-frequency diaphragm.
This tri-amplified configuration allows dedicated power to each frequency band, minimizing distortion while maximizing headroom. With a frequency range of 55 Hz – 20 kHz and maximum SPL exceeding 130 dB, it delivers tight, deep bass, lifelike midrange detail, and crystal-clear highs.
Furthermore, its high sensitivity (94 dB LF / 107 dB MF / 105 dB HF) ensures efficient power handling and consistent output, even in demanding playback conditions. For professional applications, it pairs perfectly with QSC amplifiers such as DPA Series or CXD Series for precision tuning and optimal system performance.
Advanced Technology & Features
The RSC-112 integrates several proprietary technologies that set it apart from traditional cinema loudspeakers:
Directivity Matched Transition (DMT™) – Delivers seamless frequency integration and uniform coverage.
Tri-Amp Design – Allows precise control over LF, MF, and HF sections for maximum clarity and power efficiency.
Coaxial Driver Configuration – Ensures perfect time alignment and phase coherence between mid and high frequencies.
90° Axisymmetric Coverage – Maintains consistent tonality across a wide seating area.
Reference Monitor Compatibility – Works within QSC’s Reference Monitor System, including the RSB-212 Subwoofer, for full-range cinema sound.
These innovations make the QSC RSC-112 a trusted choice for professional engineers who demand fidelity, reliability, and system flexibility.
Connectivity & Integration Options
For seamless system integration, the QSC RSC-112 is equipped with NL8 SpeakON™ connectors, supporting bi-amp or tri-amp configurations. Its wiring architecture allows fast connection to dedicated amplifiers, while the M10 rigging points offer flexible mounting for behind-screen or overhead installations.
When integrated with Q-SYS™ networked audio processing, users gain access to factory DSP presets, including EQ curves, crossovers, and time alignment, ensuring consistent performance across installations. This compatibility also enables remote monitoring and tuning for large-scale systems.
