1. Description

This horn loudspeaker can be used to approximate

a point source of sound and is better suited for

acoustic experiments than large conventional box

loudspeakers. For excitation of a Kundt tube, the

outlet of the speaker can be directly placed at the

end of the tube. For the Chladni patterns, it can be

positioned under the Chladni plate.

The dynamic excitation system of the speaker has

thermal excess current protection.
