I purchased a pair of Vandersteen 2c's in 1982 and still have them. Over time I have had to replace 2 of the drivers. I have also on occasion have called the company with other questions.
Amazingly, every time I call the Vandersteen company, guess who I talk to? Yes, none other than Richard. And, he virtually won't let you off the phone!! He has a very easy going, compassionate style. How can you not like the man behind the product!
