Plane Wave Speaker 30W ยี่ห้อ TOA รุ่น PW-1430DW
The Plane Wave Speaker features a flat speaker system equipped with plane wave units, realizing a narrow directivity pattern by radiating plane wave sound. Since the Plane Wave Speaker can deliver sound output toward a limited target area, it is suited for use in locations such as station platforms and escalator areas that require information announcements to be broadcast, and in such spaces as museums and art galleries where the reverberation time is long. A double-sided radiation type radiates sound both backward and forward.
