TOA / F-2321C

The TOA F-2321C is a wide-dispersion ceiling-mounted speaker system that achieves an extremely wide coverage area through its unique acoustic structure. It is compatible with both high-impedance and low-impedance systems, and provides a uniform sound quality balance not only directly below the speaker, but also in other areas.
