Can someone please tell me what is the largest, or best speaker, to fit into a Dapol 7mm ‘Terrier’?
I am waiting delivery of a non-sound fitted loco and I want to fit it with sound. In the mean time I am going to order a Zimo mx644d 21 pin sound decoder 30x15x4mm from Digitrains but I don’t know the internal dimensions to work out the space available for the speaker.
Thank you
Willy
