outta what i did with my subs... DD took the biggest beating and handled more then 3x the rated power without a problem.. try doing the same with the "other subs" and you wont get half as far.
Other subs dont get reconed because of a few things....
Cheaper to just by a new same model sub. Company doesnt offer Recones (Like JL) because they like to sell more of the same products...
Another reason so many are reconed.... DD, FI, SS, ect are mostly used in competition setups so its being beat to sh1t for the most part
