I got to message a DD woofer builder a decent bit my last stent of box designing; they would send me designs to do for or with individual customers. It was super fun for me. They do some cool stuff over there. One of the famous arguments about woofer break in or not, I was told directly the break in has to do with the resin in the spiders, and they show that there. I got to do a Scion 2x 9918 clamshell like box and some others, those 9900's I like. I still think DD makes some of the best looking subs, like their carbon cones look really good to me. Great vid!
