Brown nose much? Not at all, we do this for our partner supervisors on the night shifts. Just playin bro. I'd buy you a kick ass meal just because good people are hard to come by. Seal them. XBL2 is an amazing beast sealed. I have some Brahma MKIIs ported in my GN, and I ported a pair in my HT as well. But honestly, when I went sealed they sounded so much better. I went a bit small in the HT, and I suggest you do the same. 18s?

They have so much linear motor that they kick ass sealed. I know the Brahma MKII was sealed QTS with a borderline EBP, but I also had some Tumults that did better seald (IMO). Honestly, I prefer sealed, and even better IB (I have kicked around IB with my Brahmas), so perhaps my opinion is biased; but as a former Adire dealer with several XBL2 drivers to play with, and having played with several others, I can lend a bit of personal insight.
