Lexikon Chassis specifications

Category : Lexicon

The term chassis comes from the time of tube devices, which were still built in free wiring without printed circuit boards. The components such as tubes, transformers, etc. were attached in the device to a construction made of steel or aluminum sheet, which was usually placed at ground level.

Often this metal construction is not directly accessible from the outside, and there are devices in which the chassis is potentially at a dangerous voltage with respect to the ground, so that you have to avoid any contact with the open device.

In newer devices built on the basis of printed circuit boards, a chassis in this form often no longer exists, and the role is taken over by the metallic housing. In this case, the housing is often referred to as the chassis.

In the case of loudspeakers, the term chassis refers to a construction consisting of a basket, a diaphragm, a voice coil and a permanent magnet. Real loudspeakers contain one or more such chassis, plus possibly other components such as crossovers.
