J-C, your speakers are probably fine. I have eight old Seeburgs (V-Vl_K-201) out with original speakers you want to test them just connect them to a typical amp and listen. Use moderate volume as these do not have high power capability.
A slightly more revealing test is to connect a 3-5 volt AC supply from a 60hz line. This will show any rattles.
The best test uses an amp and signal generator to sweep from bass approx 50hz (don't go lower on those speakers) up to about 600Hz. This will easily reveal any rattles or rubbing voice coil noise.
I find it best to check the speakers when bolted into the cabinet. The reason is that slight warpage of the baffle board might in-turn shift the speaker frame and cause a rubbing voice coil. One of the speakers Wurlitzer is particularly susceptible to warp damage. That one has a particularly small voice coil with tight clearance. IIRC that one is on the left as viewed from rear.
As for removing the speakers, if you remove the title board and rear doors and contort yourself a bit, they can be removed w/out taking the mech out.
Seeing the stripped cabinet reminds me of how flimsy that model was. An old op used to say that "they do a little dance when moved". Still, that series and the 1800 were my favorites of the Wurlitzers.
