IMHO two tv3612 would give you more TR & ULF than the V18. 18hz tune vs 14hz tune.
Yeah, I am still torn on the x2 and x4 but the more you read the more you learn that not only a square room is bad, but sitting in the middle of the room is the worst. There is some extensive research out there and Toole and this Audioholics article
specifically seem to say you can fix most small square room center seating with 4 corner loaded subs. So, that's what I am going to do. All that said, I notice the trend is everyone moving towards 2 large drivers in one cabinet setups and hopefully I am not making a mistake keeping things traditional, haha.

This is the logic that keeps circling around in my head. I am getting mixed reports which of these 2 subs reach lower. We know from all the extensive reviews that the Monolith goes real low but logic says the 18" should go lower. However, there are some recent posts that show the V1812 dropping off real quick at 20hz which may have just been a design decision. I am not smart enough to know the truth yet.

So, on this. I know the version 12's IPAL and non-IPAL both have new drivers. But, there isn't any fresh reviews or a lot of info that I can find. Is the v1812 a low-tuned option?

Why spend 5 grand on 4 subs that combined (1812's) won't put out the same SPL at 16Hz as a single Monolith or VTF?
I do have the MiniDSP HD, Umik and REW/MSO and am super excited to dial whatever I get in. Usually, I would have to think the 18" drivers would go insanely low but the few measurements I have seem to say the v1812 has different design goals. Similar to PSA speakers. Maybe, that is fantastic though, since I am getting all PSA speakers. I am woozy from all the thoughts and everyone seems to be right down the middle reinforcing both arguments in my head.
