Perhaps I'm not searching properly, but I'm having a hard time figuring out the production timeline for the Tower II speakers.  Specifically, when were these versions built (drivers in a line from top to bottom)?

Ribbon supertweeter on top
Focal inverted dome gold tweeter
Carbon fiber midrange with phase plug
Dual carbon fiber woofers with phase plugs (megawoofers?)
Slot loaded passive radiator

Thanks.

These were in production from 1989 to about the end of the 90's.

One more question... how much to replace the passive radiators if they need it?  Got a line on a pair at a very reasonable (I think) price, but don't know what may lurk underneath.

Thanks for the info.
