TOA / CS-153

This horn speaker combines the waterproofness and clarity of a trumpet speaker with the superior sound quality of a cone speaker. Stainless steel angles and bolts ensure corrosion resistance in outdoor environments, and a rotary switch allows for easy impedance selection. The constant directivity horn reproduces clear sound over a 90-degree horizontal range. It can be mounted on the ST-16A speaker stand (sold separately).
