Two 15's in a b-pillar 6th

I have a small 6th order with two XMv4 15's. I've tried Zv5's, NSv3 Retro with black spiders, DC Audio Level 6 fully upgraded with every option. And now I have these XMv4 15's. They're the best that I've had so far. I think it might have something to do with them having more spider area than everyone else. I burped and outlaw kick score of 159.13 at 33Hz. Power is a Crescendo 17K wired to 1 ohm. On a 140ah CMAX charging at 15.5v. These subs are the most musical so far. They crush it from 22Hz to 60Hz and I couldn't be happier.
I want four 18's in my next build.
