QSC mid-high components are all about intelligibility. The midrange element — a 10-inch, high-output, horn-loaded cone driver — places nearly the entire dialog range on a single element, helping audiences hear every word clearly.

For high frequencies, our 3-way systems feature a high-performance titanium diaphragm compression driver. In 4-way systems, our proprietary HF/VHF driver uses coaxial diaphragms to provide superior fidelity. And because all systems include a passive crossover, we give you plenty of choices for bi-/tri-amp or tri-/quad-amp operation.
