Okay, I am one step closer to having my Atwater Kent Model 55C back in operation again. The F4 speaker I ordered just arrived today (had to patch a few cone tears with tacky glue & coffee filter paper, but not a big deal), along with the mounting "hook" bracket that fits in the slots in the speaker tab. I still need to make a new speaker mounting board, as the original is totally missing from my cabinet (parted out before I got the radio).

Now, here's the question: I see that, besides, the tab with the slots for the hanging hooks, there are also holes around the perimeter of the basket. Did Atwater Kent use the hanger as well as screws through the holes, simultaneously, with the hooks making it easier to install the speaker screws without it falling down? Or was the hanger used alone in some applications? Or just screws? Just how would it have been mounted in a console cabinet (NOT including the Kiel table cabinet - I know the speakers in those fired downwards)? Can someone please post some good photos? Thanks!

The 55 was a very popular model.
Many independent companies made cabinets that could hold it.

AFAIK the factory installations just used the hangers, no screws.
What might have been done with other cabinets is anyone's guess.

A number of "F" type speakers were used in consoles. F-4, F-6 and F-7 for sure. On these, the speaker "hanger" was spotwelded on the speaker and the Atwater Kent model/serial tag was attached to the speaker frame.
F type speakers were also put onto small metal cabinets to go along with certain metal box sets to use as external speakers.
These include F, F-2, F-4, F-4A, F-6, F-6A, F-7, F-7A, etc. For these the metal hanger is not used, but that's where the screw holes are used. The same frames were used in both cases. On the external metal speaker cabinets, the model/serial tag is attached on the rear of the speaker cabinet.

I managed to find the correct type of hanging hook and made a new speaker mounting board for my cabinet to replace the original, which was missing when I got the radio. Put felt around the opening, installed grille cloth, and it looks and sounds great!

On my 55C, the speaker hangs on the hooks and there is also a wooden retainer bar held in place by a single screw to hold the speaker flush against the speaker board.

The wooden retainer bar is mounted at roughly the 4 o'clock position on the speaker board. I have seen the wooden clip used on some other A-K models as well.

Can you post a photo, please? Like to see the retainer bar...

Thanks! NOW the instructions about pivoting a wood block, in the original assembly instructions, makes sense! I'll have to make one of these.
