I just got some Ti2 15 subs and noticed the coil is black on both of them. Usually this means burnt but when I hooked them up they worked just fine. Had me baffled so I am wondering if PG has some sort of black coating over the coils?? Anyone knows??

May be it's the enamel coating color. Just like the wire in transformers come in different colors.

I will say that brand new Ti2 subs have some sort of glue, epoxy, or something that literally burns off after a couple weeks. Not sure if it's on the coil or not though. It does smell like burning coil when it is burning off though. Probably unrelated though......

I finally managed to get a decent pic of the coil lol. Pic is attached to this post so let me know what you guys think...
I am thinking its some sort of coating cos the sub plays just perfectly fine
Just curious cos I never seen a sub with a coil intentionally colored black lol.

It definitely looks like a coating on there.
I'm trying to look at my elite12. But they put a nice screen around the basket. So I can't see the coil. But trying to see inside it looks black as well.

If you can't smell a burnt smell when you stick your nose up to those vents, then that is just a black varnish on the coil, not cooked varnish.

My Ti215d4 has the same black voice coil. "High Temperature CCAW Voice Coils" as noted in PDF manual. CCAW is Copper-clad aluminium wire. Black color help to increase heat dissipation by infrared radiation.
