I have 2 dd 3518s, they are supercharged with the 8 inch dry weave caps, orange dd logos, dual 2 ohms, and they are very stiff with just a few hours of play time. Im looking to trade for 2 level 6 dc 18s, or some ia warden 21s, I will consider btl's as well, ive also got an m4 that needs to turn...
