Seeburg 100B speaker

[prime]

Hi guys i picked up a 100B that has had some alteration done to it, a Radio Shack amp has been wired into the selection receiver, im in the process of buying an amp for it but will also need to replace the speaker, the speaker in it currently is not an original. Does anyone know what models i can use to bring this back to original sound.   thanks pete

Hi Pete,

I will give it a try - hoping somebody corrects me if I am wrong.

Originally M100B used a 15" field coil speaker made by Jensen, 8 Ohm, field coil 5.6k.
One (maybe best) option is trying to find a good original one - check with Bill Butterfield e.g. at [e-mail]

When looking for a new replacement I'd say one of these three should work:
P-A-C15K
P-A-C15N
P-A-P15N

The first two with ceramic magnet are more close to speakers from the 1960s era while the AlNIco magnet (P-A-P15N) fits sound of 1950s era better.
It is for sure a matter of money.
I would recommend to check the measurements of those speakers with the needs in your M100B.
Though they are licensed Jensen reproductions there might be minor differences.
All will need a load resistor of (I think so) 5.6k because those are not field coil speakers. I don't know of any reproduction / new such speakers.

Hopefully somebody else can throw in some thoughts and suggestions.
