first off alot of subs can take it because your not going to truely feed it 6000-7500 continuosly. Your not going to play the exact same note constantly let alone keep up with the voltage and amp draw. As the speakers move back and forth it changes the load to the amp so it isnt going to be the same either.
So any top end sub will do. DD, T3, FI, etc.
Oh and if you were able to feed it a true 6000-7500 continuosly, you will blow apart any and every sub. Very few can take that real power without creating major internal heat and unwinding the coils. Coils can only handle so much before you burn them or the glue gives and unwrap in the gap. DDz subs I have seen hold up but still end up going in the end
