A friend just spoke to Jason from Vandersteen and this is what he said "Yes, the 2Ce sig 2 has a new mid range driver. The woven composite cone of the Quarto Wood.
The tweeter is from the model 5. So, it's just the mid-range driver that's changed. Jason also mentioned that the speaker is also
more efficient, they can play louder. Vandersteen wanted to consolated the number of drivers in their growing inventory. Also,
Jason mentioned that they were not sure the new midrange driver would work but were able to use the same crossover with minor mods."
