What make of speakers are these?

Hi, I've been reading all the posts about the different speakers in Music Man amps, trying to find something that matched my speakers, but I couldn't seem to find anything that is similar to what I have in my 2/12 65. I really like the sound/tone I get from them and was hoping you folks could help me identify them in case I need to repair or replace them someday. Maybe I'm missed something, but here goes...
My Amp is a 2/12 65 with the 12AX7 tube. The speakers have no markings on them that I could find on the back side. There is a 5" round magnet(unmarked) and the housing from the magnet to the outer rim has many open circles on it instead of having the metal "arms" from the magnet to the outer rim.
That's all I got, Thanks for any ideas.
Dave.

That's probably the basket speakers, unless they have been changed. THere should be a code on the "rim" of the speakers, but you will have to remove them to see it. It will probably start with 67-XXXX or something like that. Look for that and let us know.

Thanks Mike, I think I'm going to waite until I have to pull the speakers out for repair or something to find that ID number. Ya know the old, "If it ain't broke..." I use that amp a lot and just can't bring myself to open her up.
Thank you for your quick responce,
Dave.
