i've got refurbed 06's with black cone. i don't know whats the difference in them but they do good. i'm pushing right around 1000 rms a piece to them and they seem to do fine. i've never smelt the coils so far and i push them pretty hard
i don't know if i dare say this but it was threw some company on egay. i got then both sent to my door for 310 or so. i couldn't complain and they work great
i have 2 12's 08s feeding them with a zx1500.1 sound awesome bought both of them for 400 brand new shipped //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
the questions he asked were answered, should i have included the color of the cone? maybe the number of screws that attach them to the enclosure? Maybe you should help us out and fix where we went wrong?
