Identity of mystery speakers?

[Evan05]

Can anyone help identify these beauties? Another curb side recovery (don't laugh I just found a beautiful set of AR2's in the same block). No identification or clues on the back - just a fuse bracket and toggle switch Lo-Med-Hi. 20"w x 29" x 14.5"d There is a port at the bottom rear for the bass, I presume.
Any close or help much appreciated.

No clue but how do they sound?

Do they have the speaker inputs on the bottom? I think that they may be a later realistic optimus something

 

[Evan05]

No just terminals on the rear, along with the lo-med-hi toggle switch (weird?)

I know the low-med hi is on my optimus 5b's-that is where I thought they may be similar.

Pop the drivers out. Show us some nudes.

Looks to be a phillips tweeter in them, not sure on the other drivers though. How do they sound?

The mid with the cracked foam surround looks like a replacement. Much newer-seeming than the other drivers.
