The paint used was Behr Tortoise Shell.... or some type of turtle... add that to sea life paint color names.
The Def Techs have done me well. I understand that I am giving up some with in walls, but I am happy with the sound. Being able to aim the tweeter is a big plus. I listened after installing with the tweeter straight on, then aimed them toward the listening position. Big difference with them toed-in.
The grills and the painting process is easy but requires a paint sprayer. With them mounted, the paint looks solid but if you hold the grill up to a light you can see thru it a good bit.
I have had a pair of Myths 8's, not able to toe those in when on wall and less bass from 8's.
