Thiels are great. I had demoed a few over the years. Some of the smaller drivers focus the range or "sweet spot" in the midrange. This is where you get lots of those "juicy" details. Thiels and other companies such as Proac, AE use small drivers and they sound fantastic.
My current speaker uses a 3.5 driver.
