Might be too tight of a fit to work w/o the slots. I'll know later.
Unusual mounting for a pedestal speaker, upside down. No reason why based upon cabinet design that it wouldn't be fine. Other of course removal and installation may require three hands! The slots allow for positioning the speaker up against the speaker board. A little adjustment there for slight variations in the hole position. Nice radio.

Well, it isn't really a pedestal speaker in that the mount on the back doesn't extend down below the bottom of the speaker basket. My 38-116 has the same mounting setup. It's really more of a "the speaker was a little too heavy to be supported by the sound board so we had to do this" style speaker
When this adventure started I had only a nice 38-1 chassis and speaker. I had no idea how each would be mounted in a cabinet-------if I ever found one. I appreciate all the pictures and comments all of you have shared. Thank you.
