Vandersteen 2ce Signature and Signature 2?

Beetlemania,
I checked on 3 pairs of Signature 2's and you're right. They all had the little 30th anniversary sticker. 
The ones I'm looking at are supposedly in mint condition and they look it from the pics.
Thanks a bunch.

Greetings
 FYI the 30-year anniversary speakers are 2007
The newest Vandersteen Sig II offers the Vandersteen 5 A midrange Tweeter with woven carbon cone networked dialed in an acoustic chamber now to 1/10 of a DB a significant improvement!
  Looking at the Midrange driver will have threaded appearance older
designs are smooth.
Music lovers beware of wolves in sheep's clothing.

audioconnection is referring to original Sig IIs compared to current production. Both are “Sig IIs”. Note that the first run of Sig IIs did not even have the 30th plate.

Richard Vandersteen isn't one to change letter/number designation very often in his speakers. As John Rutan said, look at the drivers. The small but significant changes in driver topology will give you a clue as to what you have as long as you know what to look for.

The original question was

Any way to tell the 2ce Signature to the 2ce Signature2?

The 2Ce Signature is distinguished from the original 2 Ce by the inclusion of RV's autograph on the backplate. An easy way to distinguish the 2Ce Signature II from 2Ce Signature is if the backplate also says "30th Anniversary". *But* early Sig II's had the 2Ce Signature plate with "II" added to the serial number. [of course, there are many substantial internal changes, also]

I know because my pair, purchased January 2008, was the latter case. Circa 2012, RV upgraded to the midrange driver to the "woven" diaphragm that audioconnection referenced. This is an improved, but un-named, version, ie, still "2Ce Signature II". RV (and many other manufacturers such as Ayre) often includes running improvements in his models but only changes the name when he feels they're significant.

If you want the very best performance you need to buy current production. But $1000 for the first iteration of the Sig II will sound really good and is a good deal.
