That was my concern as well. Initially, I was hoping the OP was considering an IB configuration because I knew the enclosure would be quite large, lol. Power handling is decent and Qts is acceptable but Xmax is coming in at around 16mm, who knows what the dynamic mechanical limits are.
OP, if there are two guys to trust with their input about drivers, Alex and Jacob are those guys.
Thanks for reinforcing those numbers Jacob. It was getting late and I wasn't 100% but I was pretty confident. Millicubic meters, huh? Lol. I need to buy that program.
