So much for open baffle on that bottom woofer. Did you throw your back out moving that thing around? 
They do weigh about 20lbs each, now. More of a bicep workout than anything

Oh God, it was such torture resisting the urge to buy these speakers, which is somewhat local to me, but I need another pair of speakers like I need another #$%$!
Enjoy 
Thanks, it was such a great deal I couldn't pass it up. If you know anyone that wants to buy my old Spatial X3's, send them my way

WOW! that crossover is crazy. Can you tell me what all you have in it? Do you think the Otica's are to much for a 18x13 enclosed room or should I look at the NX-Studios.
Inductors are all Jantzen copper foil in wax, the big caps are Miflex copper, the smaller caps are Janzen Alumen Z Cap along with a pair of Clarity CSA caps. Resistors are Duelund Graphite. Yeah, it was really expensive, about $3k total ($1500 per speaker). It definitely brings in that last 15% of improvement. Which might not sound like much, but when the speaker is already world class, like the NX-Otica is, then even small improvements become significant.
For your room, I'd probably do the NX-Studio on top of double or triple subs. Or, if you are patient, GR Research is designing a slimmed down NX-Otica, a little brother using 3 of the 8 inch Servo subs. Here's a pic of the mock up:
