Is there a huge diff, between 2CE Sig II & 3A Sig?

With the Velodyne, I would expect the difference to be smaller than if you were simply moving from 2 to 3 without a subwoofer. Depending on the model you have, I think the 2s and 3s may have the very same tweeters and midrange and I would expect very little difference in the range covered by these drivers. Now if no subwoofers were involved I would say you would get a noticeable improvement in bass and dynamics - but never would the differences be huge - a huge difference would mean leaving the Vandersteen stable, which it does no sound like you are interested in doing that. If you have the cash, why not? If you would be pushing it financially I would stay put.

I think the biggest difference is price.

You guys (or girls) really are not that knowledgeable about Vandersteens, and yet you give advice to someone who's serious about his question. Unsound...the name is perfect. The Signatures are individually tested in a chamber and have to pass the design guidlines. Not only is the Sig bigger, but cleaner, clearer, greater dynamics...all that you would expect of a Signature designation. Get on Vandersteen's website and at least read if you can't listen to one....but stay off this site if you just like to see yourself in print with no foundation of truth. Mike....call Richard...he's a really nice guy and let him explain what the differences are himself.

Stringreen, don't tell me where to go, or presume to know what I use a foundation of truth. Sure, many of the differences you suggest are true, but, I still think they have more in common, and the biggest difference between them is price. I've heard all the Vandersteen's many different times, in many different places, and in many different systems. All of which has led me to conclude that the Vandersteen 2's are an incredible value, and the 3's start to encroach on diminishing returns in comparison. You might value them differently, but I don't go out of my way to publicly insult you.

I do agree that the 3s are clearer with greater dynamics, but I also think that with the use of the Velodyne, the differences are much less than a straight up comparison. If money we not an issue, I would certainly choose the 3s over the 2s, but with subwoofer used with the 2s versus a straight 3 the choice would not be so clear. I have owned 2s and 3s and 2WQs so I have some knowledge of the Vandersteen line, but it is always a good idea to talk to Richard, and better yet, get yourself to a store and decide with you own ears, you should be a able to get a demo - in either case, both speakers will be better in the midrange with a subwoofer taking some of deep bass duties off the mains. If I am not mistaken, the current 2s and 3s use the very same tweeter and mid-range driver - no?
