Intermountain HO GP10 speaker

[squeaky]

I have just ordered an Intermountain GP10 with DCC. I will be adding sound. From what I have discovered from the net so far is that it uses an ESU 21 pin decoder, so I will purchase the sound version probably an ESU 54499.

 

Can anyone tell me what size speaker is needed and where does it go?

 

Thanks

So after waiting nearly 8 weeks for the GP10 to arrive it arrives on my Birthday! What a great present for myself.

 

Well this is what is looks like out of the box.

 

This is with the body off confirming that it is fitted with a 21 pin decoder.

 

This is where he speaker will go looks like you need a 35 x 18mm rectangular unit to go in there or anything smaller.

 

So for anyone looking to buy one of these you will need a 21 pin sound decoder, I'm using an ESU 54499 and you will need a speaker that is 35 x 18mm or smaller. The decoder comes with a 40 x 20 mm in an enclosure which is too big.
