I think there's more to it than that. The mono sub tends to be omnidirectional. Case in point, the dipole wouldn't be doing its thing if the bass wasn't wrapping around the baffle.
Which then creates significant velocity at the sides. This causes a lot of confusion I believe. Linkwitz has explained this and I think it has been misinterpreted a little.

The parts express corner dipole design is my adaption of George's for 15s. It sounds great with music to me but is spl limited below 30hz. I've found that it performs the best with one of the woofers in reverse polarity. So you get + output from the left and - output from the right and the back (in the corner) is a cancellation.
I've found this design to sound great with bass guitar especially a song that has quick note changes. The slam of a kick drum is better handled by my 7foot 40hz folded horn towers.
I'd like to do some experiments with acoustic elegance drivers in sealed enclosures because I'm not sure how much of the magic is the dipole or the high quality drivers.
The picture earlier in this forum is with it upside down. The common opening fires into the corner.

I meant single baffle like this http://www.kingdom.uk.com/jdfiles/side_open_right_full.jpg I found it worked better than the CDW which I tried also. I got the baffle right into the corner, it worked surprisingly well so long as I wasn't in the null.
That was also my idea, and I built two sealed cabinets located in different corners .....
This article finally convinced me
corner loaded louspeakers
Only I didn't go for dipoles, I preferred to use two cabinets for each speaker, it helps eliminate room modes, and you have more total SPL
I see the possibilities with your OB corner horn placement. The rear wave firing upward with gusto would cause its wave to take extra time to come around and cancel. Almost like cardeoide. Can't spell it.
But I've also given firing a sealed box into a corner like you've stated. The sealed box (faced into the corner) could fire into a pair of half-round pipes to direct the sound waves smoothly to the walls. Could even place a large half pipe the size of the cabinet on the backside of the cabinet that faces the listener for an even larger horn.
