I have a level 5 15" that i got about a year ago. It is blown but i do have a the recone minus the glues cuz they dried out. $150 w/o the recone $200 with it.
Theres a sticky somewhere around here about packaging subwoofers. Basically a swimming pool "Noodle" around the sub mounting rim and double boxed iirc. It would get pretty expensive shipping it. Id better pass. GLWS tho.
