As Johnny pointed out, owners of the 2WQ are probably going to upgrade when the Sub 3 comes out, so, as I said, there will probably be a few 2wq's for sale in the near future.
I would not expect Vandersteen to discount existing stock. And, if I were him, I would just sell existing stock before offering the Sub 3.
@mvlopez, Good question.
Though I am thinking there should not be a change. The EQ is more of a 'fine tuning' of the signal. And, the 5 and 7 speakers use the same crossover, I believe.
