The S90-f/c highly efficient design yields fast, dynamic, articulate results with accurate timbre. This is a high-end subwoofer solution for customers who desire no-compromise performance, but prefer the aesthetic benefits of custom-installed, hidden loudspeakers. The S90-f/c has superb performance characteristics, which include a flat response to 20 Hz with usable in-room energy down to 17 Hz, outstanding dynamic capability, and accurate timbre reproduction. Three versions are available: S90i (when an exposed grille is needed), S90 basic-port (when you are going to place it behind scrim cloth/acoustic fabric and you do not need a grille, and S90-f/c (when you need to extend the port of the S90 from the attic, crawl space, or an adjacent room).
