Vintage Columbia Tube Amplifier Guitar Speaker... Not able to find any information regarding this oddity.
Dimensions are 15.5"X10"X7.75. Speaker housing is wooden and we could clearly see tubes lighting up through back grill. Did not open speaker as we did not wish to risk damage or disconnection of wiring. We connected speaker to headphone jack of older Zenith stereo for testing.Volume, treble and bass control knobs were adjusted and responded well. Sound was clear without distortion, Did not crank it up to highest level, just slightly higher than mid-range. Front grill is a gold metal as you can see.
Very unusual and probably quite rare. Would estimate it is from the 1950's.
