The white version of the TOA Electronics PW-1430DW Plane Wave Large Double Throw Speaker is designed for public address applications that require narrow horizontal and vertical directivity such as broadcasting announcements on a railroad platform or along an escalator pathway.
The speaker utilizes four encased diaphragms with printed voice coils and magnet assemblies to generate a magnetic planar waveform that radiates less than a point source speaker. The narrow horizontal and vertical directivity reduces surface reflections and the effects of room coloration. This is especially helpful for environments with hard parallel surfaces such as art galleries and museums where long reverberation times can compromise the clarity of the treble response.
The double throw speaker is dipolar, meaning it projects sound both forward and backward. This figure eight directivity pattern further reduces room coloration because the forward and inverse backward waveforms combine to lessen and delay the first incidental wall reflection. The speaker includes a built-in beam-tilting function that enables you to shift the sound radiation direction approximately 5° downward off the horizontal axis.
It also includes a built-in high pass filter and an integrated hanging bracket for installation. The unit is constructed from stainless steel for rust resistance and is compliant with IPX4 (IEC60529) water standards, making it suitable for installation in covered outdoor spaces that are protected from the elements.
