Hi, Les

Have a couple Type 12CA 12" speakers in enclosures here.  Think they are 600
ohm (have a transformer inside).  Unfortunately, think the cones were built
to be explosion resistant and as a consequence, frequency response is
"somewhat limited".

Built in 1944.  Enclosures are wall mount and feature a volume control in
the lower right corner.  Will likely bring them up to Hamilton, possibly
replace the speakers with Jensen types, even though the thought of that
makes my insides twitch a little.
