I typically have had subwoofers in corners with the driver facing away from the wall. There would be a couple of inches between the drivers/port and wall, how much of a impact in the sound do you guys think this will make? Quick searches show that this should lower the tuning but also muddy the mid-bass, which is the bass I prefer to have sounding strong and clean.

The sub is so large and heavy not sure what to do at this point.
To be honest this is the second time I placed an order with JTR. Back in 2011 when I put my first order in he was a lot more responsive. I hate to say it but if I knew now what I did when I put the order in I probably would have gone with something else which is unfortunate.
I'm sorry to hear about the mix-up, and I agree that you should get what you wanted, and what you ordered, so I would go ahead and contact Jeff about it ASAP. But, while you wait to hear from Jeff, and wait for an exchange, you may still be able to use the subwoofer and perhaps it will still work well for you. This is called making lemonade out of lemons.
Seriously, I wouldn't prejudge the result if I were you. I would give it a try and find out whether it will work for you, while you wait, if nothing else. I am having trouble visualizing why the subwoofer would have to face a wall? If the 4000 is going to be parallel to the front wall for instance, and near a corner, why can't it face away from the corner and back toward the display?
Subwoofers can, theoretically at least, play well regardless of the direction that they face, because the bass frequencies radiate omnidirectionally from the cabinet, anyway. But, the frequency response can change, depending on cabinet orientation, as the acoustic center of a subwoofer is the center point of the front of the driver (or between the two drivers, in this case). It is a good idea to keep the port at least 4" away from a wall, so that the airflow will be unimpeded, but there isn't necessarily a problem with a driver firing into a wall. Some people end-up getting the best frequency response that way.
You should certainly do whatever you think best here with respect to leaving the subwoofer in its packing materials, or with respect to experimenting with it while you wait to hear back from Jeff. But, I don't think you can predict that it won't sound good, due solely to its cabinet orientation. I hope this helps!
