Speakers for Bachmann Big Hauler sound cards

[GAP]

I have a couple of the old Bachmann Big Hauler sound cards that need new speakers.
Where do others source their speakers?
Also is it still possible to obtain the old style Bachmann Big hauler sound cards?

Any 8 ohm speaker that will fit wll be OK.
I don't think Bachmann have ever sold the sound cards on their own.
