This gold frame Utah speaker was removed from a Vox Grenadier X PA cabinet and was probably a replacement.

The frame is stamped with the following Vox Thomas Organ Company speaker parts code:  33-5079-6.

The speaker appears to have a slight voice coil rub on one side in the area of the cone seam but sounded fine when I played it through a low power receiver. 

The silver paint you see on the cone and on dust cap were added by a prior owner.
