ESU Speaker 50342 - 9mm x 16mm x 3.0mm square, 8 Ohm, with speakerbox, 0.5W

This rectangular speaker is slim enough with a width of 9mm to find its installation space even in small H0 or N-track models. Despite its small dimensions, volume and sound are surprisingly balanced. The speaker comes with a matching sound capsule and is a real alternative wherever a larger speaker cannot be accommodated.
