I have a T2 that is missing the lower cabinet speaker. So, I have no idea if the other two speakers are even any good, since you need all three to complete the circuit to test the audio.
So, I could either get a substitute for the cabinet speaker, or just bite the bullet and replace them all with a set of pinball pro speakers. No sense in trying one option, then the other if something doesn't work properly.
I also might eventually consider a pinsound board, especially if the original board ends up not being easily repairable (and since the fidelity of the original sounds/music isn't terrific in the first place).
Has anyone found a speaker upgrade for early WPC games to be worthwhile or not?
