reginos:

Question: The symposer on 991.1 was just a duct at the back of the cabin letting engine (induction) noise in the cabin. Is the 991.2's the same concept or a totally artificial one like BMW for example?

The 991.1 symposer had the resonance chamber with the diaphragm too, the change seems to come in that it now has two of them because of the lack of real sound coming from the outside into the cabin, and I don't know if the design has been tweeked as well or not, but the concept is still the same I believe, very different than BMW which is sound recreated through the speakers though.
