As long as the speaker’s resistance is a minimum of 8 ohms it will be fine. Any less and the amplifier on the decoder will at best get very hot, worst case it could burn out.

Usually a built in speaker is connected to 2 pins on a 21 pin decoder which you don’t get on an 8 pin plug, so you’ll still have to connect the speaker wires from the decoder to the model. Which model are you thinking of fitting TTS to?

They are older Murphy models 141 , 21 pin chip, I know that it is not correctvsoujd, but just a thought I was having 

They only make 8 pin tts decoders so you would need to use an adaptor, it might be tight for space
