Loudspeakers for great sound



Sound decoders







A very important part of the LokSound system is the speaker. Therefore, we only use specially developed loudspeakers geared to the sound decoder. Here we recommend the following old saying, the bigger the speaker, the better the sound. As such, we offer loudspeakers in various sizes, one of them will surely fit into your loco.

Another crucial accessory is the sound chamber. This helps create the necessary sound pressure for the speakers membrane and comes with most loudspeakers.

If you are not sure about which loudspeaker fits into your loco we generally recommend to open the loco and measure the dimensions with a ruler.

Since model railway manufacturers often tend to change (tacitly) the inner modifications of their locos we are not able to make recommendations in general. Therefore rely on your own observations!

Note:  These speakers must NOT be used with the old LS v3.5 decoders

Loudspeakers for LokSound (micro) V4.0

When selecting the loudspeaker the used decoder type is important. Depending on the decoder, different loudspeakers can be used as follows:
