[Hallicrafters] R-42 speaker design

[ARDUJENSKI at aol.com]

I was amazed at the great sound the old Hallicrafters R-42 produces and  
based upon technology a few generations back. Is the circuit diagram available  
online somewhere? Is it specific to that particular speaker (speaker coil)? I  
would assume it is some basic L-C circuit for limiting the frequency  range.
