TOA launches Plane Wave Speaker.
Japan, January 2013 - TOA Corporation, a manufacturer of premier audio and commercial products has recently launched new splash-proof type speaker, Plane Wave Speakers.
The TOA 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, delivering clear audio to a limited target area with minimal attenuation. The plane wave feature makes the speakers well-suited for information broadcast applications in locations such as railroad stations, where different announcements are made in close proximity.
The metal parts of the plane wave unit and the entire speaker cabinet 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.
Speakers are available in both compact (with two plane wave units) and large (with four plane wave units) sizes, double-sided (backward & forward) and single-sided (forward) radiation, and black or light ivory color variations.
