Features Narrow Directivity. Splash-proof Construction. Rust Resistance. Beam-tilting Function. Built-in High-pass Filter. Description Product Description The TOA PW-1230SB Plane Wave Speaker is a flat speaker system equipped with a plane wave unit consisting of a diaphragm, buffer, magnet, and case, enabling radiation of sound in narrow horizontal and vertical directivity patterns.
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.
All metal parts are made of stainless steel, making the speaker rust-resistant. Compliant with IPX4 (IEC60529) water protection standards, the speaker is suitable for use in a covered outdoor space protected from the elements.
The speaker comes with a beam-tilting function which makes it possible to shift sound radiation direction about five degrees downward of the horizontal axis. By shifting sound radiation, clear audio is delivered in close proximity.
