I believe that Philco may have bought the company that produced the Timmons Talker speaker.  The can may be an LC network.  Attached below is the schematic for the 1928 RCA 100A Speaker.  The filter almost looks like a Pi Network.  I do not know what the expected roll-off frequency was supposed to be.

I will look to see if there is a schematic for the 512 speaker.
