ESU 50336 LokSound Visaton SC 4.7 ND 41mm x 70 Square Speaker ~ 8 Ohms

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

LokSound V4.0, LokSound micro V4.0 and LokSound V4.0 M4 decoders need the new speaker with an impendance of 4 Ohms. With the present 100 Ohms loudspeakers you would hardly hear anything.

Conversely, you must never use the new 4 Ohms speakers with the previous LokSound V3.5 decoder. The decoder could be destroyed! When the decoder is replaced, the speaker must! be changed as well
