Perhaps, perhaps not. Any motor topology has it's limits. The more output you try to achieve, the more drawbacks you're going to have SQ wise. Even XBL^2 starts to achieve a BL "ripple" once you start stretching excursion past around 15mm one way-Dan Wiggins himself admits that one. Not to a huge negative degree with something in the form of a Brahma, but it won't take much more to really start noticing some SQ drawbacks. That comes in the form of BL linearity, inductance, increasing MMS (which will explain the horrible efficiency of these and similar drivers), less consistency over the range of excursion in relation to BL linearity and suspension abilities, amongst other things. The XXX isn't even using XBL^2 on this one, though I haven't heard the exact topology they're going with on this one.
If you want a 3db increase, you're going to have to double the excursion to do it. You'd want the XXX to have a 62mm one way excursion with the same BL curve that the previous one did-and this one isn't going to do it. While linear excursion is important, the current route they're going with it is straight out stupid IMO.
That's why we (Glasswolf, MikeChec9, and myself) have mentioned that we are waiting on testing to what it turns out like.
