Reading all the comments, no one recognizes the XX. What should your pd try to tell you ? Obvious a remarkable hand and asking what you can support. Pd already knows you have at least 5 spades so, tell him your best second card and that is : ♣ . The KQxx is in combination with the single and doubleton adds strenght to the hand.
So, 3♣ should be the answer.

That is not the standard meaning of redouble in the slightest. Redouble highly suggests penalising the opponents, and as miamijd wrote above, telling partner they are wrong by bidding immediately has a very specific meaning.

I seem to be the only one who is happy to defend 2Dx. If partner has diamonds and hearts covered, they aren't going to have many tricks. Depending on my agreements I'll double for takeout or pass to give partner a chance to double for penalties.
