Looks like I have an exploratory project over the holidays.. Concerns would be the total cost of the guy, especially if non-Eminence drivers are involved, and sonic comparisons to the fEARful..
If I were to do a 410 cab with sonic comparisons to a fEARful, I'd build a vertical 410 with a 6" mid. It would take 3-4 (closer to 4) BP102's to equal one 3015LF in the low end and a single mid would handle the rest.
It could be a tall, narrow cab with tiltback wheels and perhaps a space for a micro head. Kind of a fEARful meets half an SVT.
