In general I'd agree w/Ron's advice (not an unusual occurrence) on this, but here the main priorities are: efficiency and resonance point. It's also worth mentioning that reconed speakers often come back with different performance from original due to whatever generic cone the rebuilder has available.
Those amps had at best about 12 watts RMS/Ch. Typical free air resonance point was 70-75 Hz. Wurlitzer used two different types of speakers for two reasons; To spread out the resonance peaks and as a sort of tone shaping. The 16 ohm spk will draw 1/2 the power of the 8 ohm and in theory be about 3 db lower in level.
Just last night on another forum a person asked about using a modern Jensen C12K2. Looking at the spec's this appears to be a good choice if you want to go with a new driver.
