Pro Fidelity S18c


The S18c is a powered 18" + 15" subwoofer with dynamic, adaptive dispersion. It is capable of creating various directional patterns, including cardioid and hypercardioid.

Due to its low tuning, the S18c is capable of providing useful output down to well below 40 Hz. Its large, symmetrical bass reflex ports ensure optimal woofer loading and turbulence-free performance even at very high sound pressure levels.

Sophisticated Cabinet Design

The S18c's cabinet is made of the highest grade birch plywood. Besides looking good, the curved side panels are extremely stiff, thus reducing resonances to an absolute minimum. The cabinet incorporates rigging hardware, allowing various mounting and flying configurations for both touring and installation purposes. Custom finishes are available on request.
