[Hallicrafters] R12 wood cabinet speaker

[rbethman]

The R-42 indeed has a switch.  It cuts a capacitor in or out of the 
circuit for either communications quality OR Hi Fidelity.

Has nothing to do with the Bass Reflex.  The R-42 has a OPEN plastic 
grill on the front bottom that is used for the bass reflex.
