The Fine Things are Always Hand Made
So, it looks like an AW23 speaker, but it doesn't have the two plugs for the tweeters and the stub cable (and no stub cable). The connector is like that used on the pointer Philharmonic (two large pins not together, not like a 23). Pin testing shows it should work on a Philly - but it is a 12 in and no Philly style tweeter connection either. But tagged Scott...I have two of these BTW...the other one has an AW23 style plug on it and tested it with an AW23 and it works great. Any thoughts appreciated. It isn't an extension speaker either - the connections inside the "Maganavox" door are the same as a 23 speaker. The manuals show a very different terminal strip for the extension speakers.
