Help identify these spaekers!

Yes, even up to 30W, those coils are larger than those used by old P12N (Twin speakers)
In a nutshell, they will take anything a couple 6V6/EL84 can put out, all day long.
A Deluxe Reverb (22W) would be fine.
But, say, 4xEL84 or 2x6L6 would be too much.

Well I am kinda hoping to drive them into breakup. I hope they do it well like a P12 or a G12H not like a vint 30.

[J M Fahey]

Agree.
Can't vouch for the others, but certainly a V30 it won't be
The "original SVT alnico 10" " I referred to were these:
As you see, that big "C" type alnico frame already looks big on a 12" ; is absolutely ridiculous on a 10"
Obviously they were going for the Olympic Gold ... which they got !!!


EDIT: to be more precise, I suspect yours will be fatter and less bright than a P12N, on account of the larger voice coil.
Not bad in my book.

The G12H play in an entirely different league.

Ya a G12H was not fair I guess I just like ceramic. these were just too "wimpy" I like a good ol' greenback and was hoping to get something like that, but not really. now maybe mic'd up and blasting loud? Sitting in front of it, boring.

I remember Music Man used some Alnicos such as these, dunno who actually made them, I saw them both silver (like these) and black (like Oxford/Eminence).
Never cared to write down the codes, although some data might be found on a MM specific board.
Later they progressed to square ceramics, which in my mind make a lot of sense.
And *vaguely* remember (may be mistaken) that one of the Ampeg *guitar* 4x12" cabinets had speakers very close to what you have.
Like everybody else, progressed to square ceramics and then to regular round ones.
In any way, they were known to be relatively bassy.
