Vandersteen 2c vs Thiel CS2

I owned Thiels (about 30 yr ago) and extensively auditioned Vandersteens (about 35, then 15 years ago). As @erik_squires said, the Thiels have very pronounced treble. That gives them great imaging, air, and soundstaging, but can make them hard to listen to. I finally built a low-pass filter to tame them. The Vandersteens have a far more relaxed -- I’d say natural -- tonal presentation. Not showy, but rewarding. They are about as far apart as two speakers can be..

@imhififan :  Regarding details of the low-pass filter, my regrets; it was too long ago, and I no longer have details. It was a simple R-C passive filter sketched out by a friend who knows electronics better than I. I assembled it into a little aluminum box, long gone.
