[Hallicrafters] R-42 Reproducer questions

[Craig Roberts]

I've just purchased an SX-42 and need a speaker to mate with it. I'm 
guessing an R-42 will be hard to locate ( though if anyone's got one for 
sale, please let me know!), so I'm planning to adopt a substitute.  This 
leads me to a couple of questions:

Does the R-42 speaker have a 500 ohm voice coil or is a transformer 
housed inside the cabinet?

Is the R-42 cabinet sealed? If it's sealed, does it have a bass port?

I owned an R-42 once, but it was about 40 years ago and I don't think I 
ever peeked inside.  I remember the cabinet being rather larger than the 
8-inch driver inside would indicate (is it really an 8-incher?) and 
wonder why, if not for acoustic purposes. I also remember the 
"Communications / Hi-Fidelity" toggle switch.  I'm guessing this 
switched in a cap network to restrict the frequency response for voice 
reception.  So, I guess my basic question about the R-42 is-- what's in 
there?

Thanks very much and 73,

Craig
