Whether configured in passive or bi-amp mode, this speaker provides the flexibility and performance needed for modern theater environments.
Ideal for medium to large auditoriums, the SC-2150 ensures precise dialogue reproduction and immersive sound across the entire listening area. As part of QSC’s acclaimed Screen Channel Series, it represents the perfect balance between innovation, reliability, and acoustic excellence.
Design & Build Quality of the QSC SC-2150
The QSC SC-2150 embodies the company’s reputation for robust engineering and elegant design. Its cabinet is constructed from durable birch plywood, chosen for its superior acoustic properties and long-term strength. The trapezoidal enclosure minimizes standing waves while maximizing efficiency, ensuring smooth frequency response throughout the performance range.
This loudspeaker features a dual 15-inch low-frequency section, a 6.5-inch midrange driver, and a 1.75-inch high-frequency compression driver mounted on QSC’s advanced waveguide. Together, they deliver accurate sound dispersion and consistent tonal balance, even at high output levels.
The black textured finish provides a non-reflective appearance ideal for placement behind cinema screens, while the modular baffle design simplifies alignment and serviceability. QSC’s design philosophy focuses on durability, precision, and acoustic consistency — and the SC-2150 exemplifies all three.
Power Output & Performance
When it comes to power and clarity, the QSC SC-2150 stands in a class of its own. With its dual 15-inch woofers, it produces deep, controlled bass that anchors the cinematic experience. The midrange driver offers exceptional vocal articulation, while the high-frequency compression driver delivers crisp detail and smooth dispersion.
Operating in passive mode, the SC-2150 provides convenience and simplicity with its integrated crossover network. In bi-amp mode, users can optimize performance by independently powering the LF and HF sections — achieving greater precision and headroom.
The loudspeaker offers wide horizontal and vertical coverage, ensuring every seat in the theater receives consistent sound quality. Its high sensitivity and low distortion levels allow for clean, undistorted playback, even at reference cinema levels.
Advanced Technology & Features
The QSC SC-2150 integrates QSC’s advanced waveguide and crossover technologies to ensure uniform dispersion and accurate imaging. The SC Series waveguide is engineered to deliver controlled directivity, resulting in smoother transitions between frequency bands.
Moreover, QSC’s precision crossover network minimizes phase distortion and aligns frequency response between the LF, MF, and HF sections. When paired with QSC DCA amplifiers or integrated into a Q-SYS system, the SC-2150 can be tuned and monitored digitally for optimal performance.
For added assurance, the system meets or exceeds industry standards for THX and Dolby reference levels, ensuring compatibility with the most demanding cinematic soundtracks.
