I don't think the JL's will be worth the cost.
Assuming you have TC9 based Orion HCCA, I have some coils that fit that motor, 12 and 15" cones, and plenty of spiders. I could ship you parts for 45-60$ (depending which size, coil, and how many spiders). I'd do the work for cheap, but the cost of shipping the motor to me and the assembled sub back would likely run you 50$.
