The lowest cost option is to fit speaker from your local consumer electronics store. Typically these come in
27mm or 57mm diameters. Use the largest which you can fit in your loco.
For a better quality sound and more volume, the speaker needs to be
baffled. That means that it needs to be built into the front face of an
airtight box so that sound is heard only from the front of the speaker
and none from the back. The plastic top of a spray paint can is good for making a baffle as shown in the
diagram.
A good solution, which ensures high quality sound with lots of deep
throbbing bass, is to purchase an 8 ohm impedance external speaker unit for
iPod and MP3 music players and remove the two speaker modules, in their
enclosures, for use in two locos. These are readily available at consumer
electronics stores.
Speakers can be connected to the terminals either way around.
