TOA / F-2321C

TOA's F-2321C is a wide-directivity in-ceiling speaker system that achieves an extremely wide coverage area thanks to its unique acoustic structure. It is compatible with both high-impedance and low-impedance systems, and provides consistent sound quality balance, regardless of whether you are directly below the speaker or not.
