QG48-

The primary problem is that the sound generators are Loksound DCC decoders. That's DCC, not 3R AC. The Alco speaker is just a 4 ohm Tang Band module. I know that a larger TB module has been fitted into the tender of a 3R Hudson steam engine and it sounded awesome in the shared videos.

In summary, there are three pieces to the puzzle: A decoder with great sound quality, a speaker up to the task to play the sounds, especially the bass, and a compatible control system.

All the best!
