Vandersteen 2xx - 100,000 units?

Use a 32 w Line Magnetic 211IA on my 2CE signatures with very satisfactory results. They even thrive on 12 w Triode.  No Difference between that and my Consonance Cyber 800 mono blocks @ 78 w, toss a coin.

These speakers do not need gobs of power, contrary to what people say.
They are not party speakers they do not do loud, that’s it, and no amount of power will make them do loud. Tried all sorts even, 500 w @ 8 ohm doubling to 1000 w @ 4 Class D on mine, Nah, wasting your time.
For loud, I got Cornscala’s.

They play music like nothing much else, that can cost 10x the price.
Properly set up you will pay big bucks to get better.

I owned the original model 2 made in the late 70s. A very enjoyable full range speaker bought for $400 used. Richard offered to buy them back in 1988 in exchange for the latest version. I did not take him up on that however.  

I think you'd have a chance in a smallish to medium room with 35wpc.  I ran 2CE sigs to good volume in a very large 27x16x10 room with a 60w ARC VSI60, but of course it's material dependent.........
I would say strive for at least 50WPC, but the only way you'll really know is to try it out.....in your space......

Here's an old video of my system in those days:

Those new sigs are really quite remarkable for the cost. Richard has always given you more than you expect at each price point. It's pretty amazing that he's been able to do it.  

Is the number real?  Yes, of course it is.  Richard may be called names by some as he's opinionated and direct (and still a great person who has passion and knowledge), but liar isn't one of them.  If you look at the years they've been out and figure out how many he makes daily, you'll realize that he's sold a TON of them.  He's one of the few who have moved from lower priced to higher priced speakers and still been able to offer value at all levels.  Few companies have been able to do what he's accomplished and that's why he's on the Mt Rushmore of Audio and is as respected by industry insiders as anyone.  He also has a great dealer network.  I've met many of them and they are all similar in that they care and will go out of their way to help customers or future customers.
