recones from mach5 are cheap right around 100. ill sell the motor for 150+shipping for starters.so a loudddd daily driving SPL sub for around 270 dollars. who could beat that.
also worth noting is that the mach 5 spl 12 uses a 7.5" spider on the 12, and an 8.5 on the 15.. so if you going to fi, they MUST know this, or..your recone wont fit.thanks for the advice. id just like to keep the basket with it as well as one is not included with the recone from Mach5
