The speaker looks like a Philco to me. Interesting that it's a permanent magnet speaker. Looking around a bit on the site it sounds like that's expected for the 650RX:

Quote:...Got this info from Ron:<P>Model 650RX did NOT use the K-17 speaker. Instead, it used a permanent magnet HR-4 (10-1/2 inch) speaker; output transformer and choke (in lieu of a field coil) were mounted in a small metal box inside the chairside unit; only the HR-4 was mounted in the separate speaker cabinet...

So the speaker may very well be original to the set - but as to whether or not it was originally mounted there I'll leave it to others to decide. It's possible that someone 'optimized' the setup at some point in its long life. Icon_smile

Some more pictures of the wiring harness to the speaker and what the cabinet looks like if you remove the speaker would still be interesting.
