I bought a pair of 4333A's recently and am getting the foams re-done. I just wanted to be sure the cones were factory and not aftermarket. I have had many of these woofers before, but just wanted to be sure. I see a slight redish orange at the edges. Is this normal. Hopefully some other members can shed some light. If they are not factory, I may just go for a full re-cone. Thanks.
