Not at this time, perhaps sometime in the future. As mentioned, we are not at the point where I feel the performance of this woofer justifies the price point. SEAS custom builds everything for us, and in order to do so - we must typically order 500 or more units at a time. I don't feel it would be a wise financial move to spend a huge sum of $$ on a component for a few custom builds
We are constantly in a process of evaluating ways to improve product performance, in many cases - since all of our speakers are heavily engineered to begin with, it is far more complex than one might imagine and replacing a component means a complete redesign of the crossover as well.
