Different versions of Vandersteen 2CE

Hi, I've heard that there were two versions of the Vandy 2ce and I was wondering what the sonic diffences are and how can you tell which version you've got (other than opening them up and checking parts.) I
Hi Issabre; There is a 2Ce signature that was introduced a year or so ago, but of course it has Richard Vandersteen's signature on the back panel. The 2Ci preceeded the 2Ce. I'm not familiar with any others. Good Hunting. Craig.
To my knowledge there are the following models: 2C, 2Ci, 2CE, and 2CE Signatures. Some models of 2CE's are upgradable to 2CE Signatues. You can tell by the serial number which is published at www.vandersteen.com. Great speakers.
