The other option to consider is to contact one of the national moving companies and see if they can add it to another load. This might be a fair amount less than $2K and they have insurance to cover any damage. Plus they should know how to pack/wrap them to avoid any damage.
I gave my NX-Oticas to my son and he took them from Portland to San Diego as part of a UHaul full of other stuff. We wrapped the speakers in cling wrap (with cardboard covering the front baffle), then moving blankets held in place with more cling wrap. They arrived unscathed despite the fact the were just loaded in the truck with a bunch of other stuff (e.g. not strapped in).
You gave your son NX-Oticas? Hell, can I be your adopted son?
3 days in a car and $600 worth of gas & red bull for a long weekend road trip. 
That'll be one hell of a fun setup!
5 years ago I would have done it that way no question. But 3 things held me back - my SUV wouldn't fit all 4 boxes, plus it's winter and I don't want to deal with snow over the mountains, and finally, I'm old

When I saw on the other thread that you bought them, this is what I figured you would do...maybe an extended Thanksgiving weekend? Heck, I'll come up from the Springs, pick you up with my Sienna Minivan, and we can do the road trip. All I ask is your Super 7s in return. 
Deal. I'll leave the Super 7's to you in my will.

And just what the heck are you going to do with those? You already have such great stuff - are you giving something up? Did you build another listening room?
J/k. A bit jealous - would love to hear those with the Tripps.
Not sure what to do about shipping though. Trust somebody to build good boxes around them and then ship, but……..Who?
It's going to be my bathroom system. You know, to help me sing in the shower.
Tyson is undoubtedly, unequivocally, and unquestionably the most audiophilic audiophile on audiocircle!
Are you gonna replace your Spatials with this setup?
Right now I have the X3's in my 2nd system upstairs and the Super 7's in my main system downstairs (also my HT is down there). What I realized is my music listening has shifted and 90% happens in the upstairs system now. So I decided to move my Super 7's upstairs. I was going to put the X3's downstairs but I was worried that the single 15" woofer would have trouble with the demands of movies in the HT.
Then I saw the NX-Oticas and triple subs for sale for a screaming deal and bought it more or less on impulse. They seem like a much better fit for the HT than the X3's. And better than the Super 7's too. I mean specifically for HT. The Super 7's still rule for music. Nothing but the Line Force can beat them there, IME.
If using the uhaul method I would be cautious of the "Movers" they are referring to. At best they will be a day labor. I used the service to get boxes inside the house and that was like hearding goats with a stick.
I was just talking with a neighbor on how I would demo drive a used pickup to haul a piece of furniture the wife bought years ago.
I wonder on getting them to a ups store where they pack and ship? Or change of company.
I do know major moving company's load a similar crate for storage or moving small apartments etc.
If the wife wasn't awaiting surgery I am up for a road trip

Thank you, that helps a lot. It got me to search around on national movers and I found this:
