I suggest you find a known good speaker and hook it up in place of one of the ones that doesn't work. If you measure the speaker diameter, you can probably find a close match on eBay or Amazon. Most speakers have an 8 ohm impedance, but some are 4 ohm; they're usually marked with impedance and power rating.
Although you can check the AC voltage going to the speaker, you have to have a load on the output. Neither a multimeter or oscilloscope will have a low enough impedance to load the output; you need a speaker or 8 ohm resistor to do that.
Aside from failing speakers, the most likely causes are bad speaker wire connections or bad switches in the radio.
