I was recently very kindly sent some speakers to try out in some N gauge locos by @roads_and_rails First up was the Dapol 68 and Farish V2 which were straightforward. The 5MT was a little more involved however...I also added a small stay alive.

Please note I have not been paid in any way to make this video, the speakers were sent to me for free, in return for feedback about how suitable they are for N gauge.
