"Can you describe the rest of the system, and the crossovers and what your design goals are to have two 12 inch woofers(vented or sealed or some other config)?"
transport, dac, attenuators plugged into Spectron amp. Crossovers on MMmtmMM (four Accuton C89/11, two Accuton C44 and an Accuton C12) array are first order series. Crossover of the two 12" (SCC-300) probably first order as well. The 12"s will be sealed or variovented. I'm using the two 12"s to match the sensitivity of the Mids and treble.

Ideally, I'd use electronic crossover on the bass, but I really don't want the extra boxes and wiring that would entail. If I could find a quality plate amp (is that an oxymoron? 
) that had a more adjustable crossover, I'd use it.
Oddly enough, my living/audio space isn't all that big (hence the desire not to add extra complexity to the electronics), but it's such an odd shape that bass isn't a big issue if I put the speakers in the right place.

I'm using the 11 ohm version of the C89. That's why four are being used instead of two.

Ups,.. sorry about the "6db" .... must be some other thread ... but your woofer should be good in closed with the medium/high Qts
C89 will roll off by itself around 100hz ..... a plateamp on those kind of woofers should be good fore that ... and you will have a little EQ fore free ... and better control with no passive components which may be important with a "high" Qts driver
But its not what you asked about - I still think you should calculate your cabinet to have the tweeter at listening height, and the rest may come by itself
