That subject came up this afternoon in my phone conversation with Fritz and the indication I got was that it was not something he was inclined to do. He did mention that there was another "mid-range" driver version of the Revelator driver that cutoff at a higher point that could be substituted but they would have to be purchased as a one pair purchase for him. That would mitigate the low end bloat if placed to close to a rear wall. Also that the "production" version of the Carbon Six was going back to the bigger box.
Another option is to buy an amp or integrated like the ones from Aesthetix that have the built in adjustable crossovers like the Atlas amp or the Mimas integrated.
