According to Richard Vandersteen, the 2ce Signature II has the same tweeter and mid-range as the 3A signatures. Here is another Q&A from the Vandersteen website:
------------
Bill (12/23/06): I just received my issue of Stereophile and enjoyed reading Art Dudley's rave review on the 2Ce Sig II. I have two questions. I am looking for 3A Sig performance but in a smaller package, how close are the new 2's? Could you explain why the anechoic measurements that John took are very flat yet the in room measurements are not as flat?
Answer: HELLO BILL, THE NEW 2Ce SIGNATURE II DOES HAVE THE TWEETER AND THE MID-RANGE OF THE 3A SIG'S. THIS AND DOZENS OF OTHER CHANGES INCLUDING STRUCTURAL PUSH THE PERFORMANCE IN THE DIRECTION OF THE 3'S. THE MODEL 3'S ARE LARGER AND HAVE MORE ADVANCED DRIVERS IN THE BASS SO THE MID BASS AND BASS ARE STILL SUPERIOR BUT THE GAP IS CLOSED AT THE HIGHER FREQUENCIES. I SUGGEST WHEN YOUR DEALER GET A PAIR AN AUDITION. I WILL SAY IT HAS TURNED AN OLD CLASSIC INTO ONE INCREDIBLE SPEAKER. AS FOR MEASUREMENTS, JOHN MEASURES ALL SPEAKERS THE SAME AND IT IS A SIMPLE PROCESS TO READ THE MANUAL AND GET THE TILT AND ALIGNMENT CORRECT FOR ANY INSTALLATION. THIS WOULD HAVE RESULTED IN BETTER MEASUREMENTS HOWEVER THEY ARE GOOD ENOUGH TO POINT OUT THE SPEAKERS TIME AND PHASE CHARACTERISTICS VERSES OTHER DESIGNS. I HAVE NEVER THOUGHT THE IN ROOM MEASUREMENTS WERE RELEVANT BECAUSE A LISTENER WOULD HAVE TO HAVE A RUBBER NECK TO GET A AVERAGE FROM THAT MANY POSITIONS WHILE LISTENING TO MUSIC. ALL THE OTHER MEASUREMENTS JOHN MAKES I APPLAUD BECAUSE THEY WILL DIFFERENTIATE BETWEEN DIFFERENT DESIGNS FOR THE READER. THE PROOF IS IN THE LISTENING.
