I'm a total n00b to this, but from what I've read, these speaker boxes are used in several games, and have now reached a certain vintage whereby the rubber thing in the speakers themselves just disintegrates. Indeed, when I prodded mine, they just turned to dust.
The original model, the Toptone F17E4U01-1 is no longer in production.
After much clicking around, I found a speaker which is 1mm less wide and 8mm shorter, whilst still being 4Ω.
May I present to you the SOTAMIA 2Pcs Rectangle Speaker 4 Ohm 10W Full Range Speaker Bass Rubber Side Neodymium Magnetic Hifi Loudspeaker Home Theater
They come in pairs, so I needed two pairs. Here are some comparison photos:


Fitting them is so easy it's barely worth describing.
You will need:


I'm exceedingly grateful to a certain member on here for making the rectangles.
NB I haven't tried these speakers yet, as my cab is still in two million bits spread across the living room. Your mileage may vary.

You will need:
- Crosspoint screwdriver
- Superglue
- 2.5mm drill bit
- little self tapping pan head screws. I took mine from a selection box, and as such I'm not quite sure what length or diameter they were
- four rectangular bits of plastic or metal, measuring 45mm x 8mm and approximately 3mm thick
- Remove the strange old sticky tape from each front each of the speaker box and discard.
- Remove all the countersunk screws from one side of the speaker box. You should now be able to remove the side panel, you may have to prise it open.
- If you're like me, you'll now take the opportunity to clean the inside.
- Observe how the speakers are wired. The replacements will be fitted in exactly the same manner, in series.
- Remove the countersunk screws holding the speakers in. You won't be reusing these screws.
- Wrestle the existing speakers out, but leave the tweeter. I found the spade connectors so tight I had to use a pair of pliers in each hand to yank things apart. In fact, on one speaker I tugged so hard a lug snapped off, and I ended up soldering the wire. Meh.
- Fit the new speakers, ensuring they meet at the centre, as shown below. Secure with two screws per speaker.
- Buzz 2.5mm holes through the remaining speaker mounting holes. Fit screws to the remaining holes. It's not a perfect solution, but I believe it to be good enough.
- Reassemble the side panel and screw in place.
- Glue the little rectangles into place in order to cover the gaps.
