Default How to open E-V TRX12B speaker to change caps?

Subject line says it all, have a pair of E-V TRX12B tri-axial speakers with the copper/bronze-color stamped frames and can't see anyway to open them up.

I'd have to think the caps - if any - are dead/near dead and should be changed, but there is no identifiable way to remove the "can" surrounding the woofer magnet..

Any ideas, please advise!

Thanks in advance!

Sometimes you just have to use the force. I know that from mini component system by Sony I used to own. Some plastic covers that imitates a driver frame and once you remove it, the screws underneath it on the steel pressed driver frame are exposed.

It might be a heavy foil sticker that won't survive being removed
The frame is probably cast alloy.

Thanks for the replies so far! I suspect that there is a cap under the "bell housing" behind the woofer...

Here are the only pics I have so far of the speaker mounted inside the cabinet and the speaker itself. Mine is the stamped-steel frame.

I can find no way inside the bell housing - no seems, no sense of any screws hidden under the EV label you see in the pic.

That's the magnet cover! No serviceable parts inside

Age alone. Doubt the speakers ever left the cabinets they were installed in, and the cabs are like 60's styling. With a horn tweeter, I expect a bit more treble out of them, but I only have seat-of-the-pants hearing to draw that conclusion.
