13 cm (5") woofer with robust polypropylene membrane for very compact subwoofer. Designed for multi-purpose applications due to 2 x 4 ohms double voice-coil, with excellent properties as 8 ohms drivers in series configuration. The enormous membrane displacement for its size as well as the very low resonance frequency allows a considerable sound pressure level, the one does not trust such a small speaker. Possible connections: (1) one voice coil not connected (2) both voice coils in series (3) both voice coils in parallel

The DPS 40 EN dipole flat-panel loudspeaker has been specifically developed to deal with particularly critical acoustic characteristics in rooms with high reverberation levels. In contrast to the similar model DPS 40 F - 100 V, the loudspeakers of DPS 40 EN are arranged as a symmetrical array. The sound is sharply focused both in horizontal and vertical directions therefore. Because this loudspeaker is normally installed on a higher place (bottom edge about 3 m), there is a passive time delay element integrated to optimize the radiating direction at an angle of -10°. DPS 40 EN is a passive loudspeaker, so it will not require any power supply. Railway station PA speakers A key objective of public address systems in railway stations is to ensure that every message relating to railway operation and in emergencies is clearly audible to all travellers at the target location in the station. DIN EN 60268-16 sets ambitious standards for speech intelligibility because the acoustic environment on railway platforms is a difficult one. Trains arriving and leaving generate very loud ambient noises and require the loudspeakers to have a correspondingly high loudness level Announcements on adjacent platforms make other announcements unintelligible unless the sound is properly and effectively restricted to the required target area Sound reverberating from the sound-reflecting ceilings and walls in enclosed station buildings generates interference noise that makes the announcement hard to understand. The passive train station loudspeakers made by VISATON will, however, allow the required speech intelligibility to be achieved, despite the difficult surroundings. These speakers are dipole flat-panel speakers, and provide the required high levels of sound pressure while focussing the sound they produce more accurately than classic speaker systems. A dipole speaker works by creating air movement (as sound pressure waves) directly from the front and back surfaces of the driver, while the amount of sound emitted to the sides, up and down is much reduced. An arrangement of several loudspeakers in line or in a single plane results in an even more closely focussed sound image. By combining these two principles, VISATON has achieved a targeted improvement in the polar characteristics of loudspeaker systems. Thanks to this principle, the platform in front of and behind the loudspeaker is addressed and the adjacent platforms hardly hear any of it. The sound also hardly reaches the ceiling and floor so interfering reverberations that would reduce speech intelligibility are reduced.Connection (100 V) + / - Red / White 40 W White / Yellow 20 W Yellow / Black 10 W Red / Yellow 6.9 W White / Black 3.4 W
