5″ Co-Axial Ceiling Speaker

The F-2352SC is a 2-way, flush-mounted ceiling speaker that offers a full frequency range and high-quality sound output. Use of optional mounting hardware permits versatile mounting to match a wide range of applications and installation locations.



The F-2352SC rear-open type 2-way speaker system employs a speaker element that is designed to provide a wide frequency range. The wide-dispersion flush-mount ceiling speaker design uses unique acoustic construction to realize a wide area of coverage. Uniform sound output levels are achievable not only directly under the speaker, but also over a wide radius. Because the speaker provides both low- and high-impedance operating capability, it can be used in many different applications. A front panel-mounted input selector switch permits easy verification and change of current impedance/power settings, even after installation. It can be quickly and accurately mounted to ceilings and the rotating front grille can be installed/removed quickly and easily. An attractive exterior design specially created by an interior designer blends naturally with any architectural space. Use of the optional HY-BC1 Back Can permits exposed speaker installation.
