The Philco service data gives a voice coil impedance of 1.25 ohms for the H-13 speaker used in model 650 consoles (among other models).

The Philco service data also gives a load impedance of 5900 ohms. 6000 ohms is pretty darn close, I'd say.

See the Philco Speakers spreadsheet available here. This is based on Service Bulletin 180-B, along with other Philco service data.
