There is a fatboy type speaker with 4 ohms that improves the sound. They were on blow out last year for just around a buck a piece! I usually order from Madison sound now.

 It does matter what type of PS2 board is in the engine. 5 volt PS2 uses a 16 ohm. 3 volt PS2 uses a 4 ohm. You could put a 8 ohm speaker in the boiler and a 8 ohm speaker in the tender wired in parallel for the 3 volt system.
