My MTH Proto 2 steam locomotive has a 4ohm speaker in it. It is not working and MTH has a replacement speaker with 16 ohms. Would replacing the 4ohm with a 16 ohm result in a better sound quality and could it be done? Thank you in advance.

You can but the sound may or may not be any better.
Quadrupling the resistance will make the volume very low, to the point the wheel noise will probably be louder than the engine sounds.
What size speaker are you looking for?

According to a chart I have the issues are small the speaker/board or very tolerant, He can put a resister in the circuit if he so desires.
I am looing to replace the 4 ohm speaker in the MTH Proto 2 locomotive tender. I can probably get a speaker online, but would like to enhance the sound with the replacement speaker without altering any other adjustments.

May I respectfully suggest you not make recommendations when you clearly don't know what you're talking about!
A 16 ohm speaker can never be made louder by adding resistance. The fact that the impedance of the speaker is four times the optimum impedance of the 3V PS/2 board means that Jon, of course, is 100% correct, it will be very low in volume.

The speakers that MTH uses are high efficiency speakers, so they're fairly loud for their size. I won't comment about the sound quality as I believe Lionel uses better speakers and gets better sound quality. You want to look for a 4 ohm speaker with dBA efficiencies in the 80's or better for good volume. Obviously, you need to pick a size that will fit in the space provided.
I put a good quality Peerless 4 ohm speaker with a baffle into my 3rd Rail (MTH PS2 3 volt) conversion and liked the sound.

Did you look at the BF-0000043 speaker. That is a 4 ohm speaker used in many of the MTH engines. It is 50mm dia round. G
You probably don't want to do more than a 1 Watt speaker @ 4 ohms. Sound drive, of this on-board electronic systems, are limited. IMO, Mike CT.
