Well 250 isnt all that bad for a type X. I also agree with phyphoestillic about the IDMAX. One of the best woofers I have ever heard overall. I would have gotten one, but little pricey at most places. If you could find a used one, then I would grab one asap! Might want to check into the Fi Q'S as well. I am getting one and phyphoestillic has two and I have heard nothing but great things about them. Very musical sub from what I have heard. Good luck!
