in corrosion or damage to the unit or its mounting
bracket that could cause the unit to fall, possibly
causing personal injury.
· Never connect a 170 Ω speaker lead to high
impedance 100 V line, as this will damage the
speaker and amplifier.

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.
The Plane Wave Speaker lineup includes the following 8 models.
• PW-1230DB and PW-1230DW (compact double-sided radiation type)
• PW-1230SB and PW-1230SW (compact single-sided radiation type)
• PW-1430DB and PW-1430DW (large double-sided radiation type)
• PW-1430SB and PW-1430SW (large single-sided radiation type)
Note: The rightmost letter of each model number indicates color: “B” for black and “W” for light ivory.
A double-sided radiation type radiates sound both backward and forward, while a single-sided radiation type
radiates sound forward only.
The most appropriate model can be selected depending on the condition of installation location and application.

• Two types of Plane Wave Speakers available: A compact type (PW-1230 series) consisting of 2 plane wave
units and a large type (PW-1430 series) consisting of 4 plane wave units.
• Sound dispersion range is narrow in both horizontal and vertical directions, enabling sound output to be
delivered toward a limited target area. Less susceptible to the influence of sound reflections from the ceiling
and floor, allowing clear sound to be delivered even in spaces with poor acoustic conditions such as long
reverberation time.
• A built-in beam tilting function for tilting sound radiation direction about 5° downward from the horizontal
• A built-in high pass filter for cutting low frequencies
• Compliant to IPX4 (IEC60529)* water protection rating
• Stainless steel-made metal parts of the plane wave unit and the speaker enclosure
* The performance of the unit is not harmfully affected even if water is splashed upon the unit from every
direction.
