ESU 50326 Square Speaker with integrated Sound Chamber, (14mm x 12mm x 5.5mm), 8 Ohms 1-2W
ESU LokSound Specific Information:
When selecting the loudspeaker for the decoder type being used 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 impedance of 4 Ohms. With the present 100 Ohms speakers, you would hardly hear anything.
Conversely, you must never use the new 4 Ohms speakers with the previous LokSound V3.5 decoder that uses 100 Ohms decoder. The decoder could be destroyed! When the decoder is replaced, the speaker must be changed as well.
