LOL, you can replace them for the cost of recone parts, besides if you're blowing up your subs you should consider upgrading to something that can take the abuse you dish out.
They have 2" coils and 2 spiders spaced 1/2" apart with no spider landing for each. It takes a pro to recone them and if the do, they are usually not the same as they were from the factory... and with a 2" coil why would you do this anyways? Type r's are trash. They can be had on ebay for almost nothing.
