Default B&C 6NDL38 anyone?

Anyone used this nice midwoofer from B&C? Appears to be the best I've seen from them so far. After finally coming across it after several days of searching for the best mid driver I could find that offered a good balance between SPL and a smooth extended response, I googled and found a bit of interest, including some words from Earl Geddes on an old Audio Asylum post form last year, although from what I gathered, it sounded as if he didn't actually have any personal experience with this driver yet at that time. Nothing of importance regarding this driver on this forum though. On another note, upon entering the parameters in WinISD pro, I only get 89.77 dB @ 1m, rather than the specified 92 dB. Regardless, I was thinking it might pair up well with one of the more sensitive soft domes? Peerless HDS 810921, the cheaper Vifa DX25, or something similar maybe? It'd also be nice to find some distortion plots, or anything else useful besides what's listed in the PDF..

With no experience or knowledge of passive crossovers, I'd probably just cross actively LR2 or LR4 to a tweeter, with the intention of learning and designing a good passive network in the near future...put it in .145 - .25 cubic feet sealed (2nd order roll off) for -3 dB around 125 Hz, and then use the active crossover for electrical 2nd order on the sealed B&C for a 4th order slope, then lowpass at 125 Hz to one of my Ascendant Audio Avalanche 15's, one per side. I've never ran them that high, and don't really want to, but they're still laying around after 2 years and I need to use them. I don't think it'd be too big of a problem. If all went well, I'd continue with another one for a center channel, with a possibility of 2-4 matching rear channels after that. This setup would be used for music as well, and even though it'd be used for HT the majority of the time, music performance is always my top priority.

By the way, I did put the Seas coaxials that I recently purchased from Madisound in some vented enclosures and had a good listen for several days or so. In the end, I ended up selling them already to a local friend. I didn't hate them at all or anything like that. They sounded okay, and did some things really well, but I think I want to try something a bit more efficient first. Not THAT efficient, as it really isn't necessary for me in a relatively smallish room, but around 90-93 dB/watt has always seemed like something nice I'd like to try for a change. For the first time, I'd like to try to shoot for good sound WITH a good amount of headroom at the same time...to where it doesn't sound so compressed at higher volume levels, yet can "work" in a smaller room within 2-4 meters listening distance at the same time.

Any thoughts/info/comments/opinions would be highly appreciated.
