Helix CiX E50-S4 – 50 mm surface exciter
The Helix CiX E50-S4 is a compact 50 mm exciter that belongs to the HELIX COMPOSE speaker platform. Unlike a classic loudspeaker it has no cone: it sets the surface it is mounted on into vibration, so that surface itself becomes the sound radiator. It is aimed at modern vehicles, caravans and motorhomes and makes efficient use of the available space.
Mounted to a vehicle’s interior panels or even to the exterior wall of a motorhome, the exciter can project sound inside or outside without any visible speaker hardware. Its small housing (Ø 52.1 mm, 18.5 mm high) can be placed where conventional speakers do not fit or would not perform well, and it is built for the automotive environment, withstanding temperatures from -40 °C to +105 °C and humidity up to 93 %.
