Thanks, Jay. I have seen that thread and that post. I do like the MTM on 2x12 build idea. It is sort of the best world. This paragraph keeps me considering the Super V, though:
"The Super Vs are not totally outclassed though. There is just something special about them that I can't put a finger on. It may just be due to the Coaxial configuration which immediately integrates the sound from the mid and tweeter. You never get the sense that you are listening to two drivers. This especially comes in handy for those of us with smaller rooms. The Super Vs hit very hard and are a very addictive listen."
This is sort of a good representation of my room. It's pretty small and with the Super Vs, I'd have them out of the wall a bit more than is pictured here. So I'd be listening pretty close, where the co-ax would seem to have an advantage.

I go back and forth between the speakers in this arrangement vs. on the long wall with my desk against the windows. I do need to think about treatment, too, but that is a whole other discussion.
Just curious, what is the total price of the 2x12 kit (with flat packs and amps) and MTM kit (with flat packs)? Just benchmarking against a used V. And I guess, what do I loose by not adopting the lower mid woofers of the NX-Otica and going with the MTM arrangement? I suppose the woofers need to play up a bit higher to meet the cutoff of the MTMs. I know the Oticas play down to about 70 Hz if memory serves me.
