4" Full-Range Ceiling Speaker

F-1522SC

The F-1522SC is a small, flush-mounted ceiling speaker that employs a full-range speaker element designed to offer a wide frequency range and high-quality sound output. It can be mounted to the ceiling panel that is up to 37 mm in thickness.

This speaker has a rear-open type speaker system employing a speaker element covering a full frequency range. The wide-dispersion flush-mount ceiling speaker design employs 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 is provided with both low- and high-impedance operating capability, it can be used in many different applications and 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 its rotating front grille can be installed/removed quickly and conveniently. The attractive exterior design specially created by an interior designer, blends naturally with any architectural space.
