Sorry. Plans changed and I am unable to delete this thread.
Went with Four X 12" Infinity 1260W's in 6 cuft (4.5 net) ported enclosures instead of the 15's. Saved space and cash.
One sub is located in each corner of my room. Very satisfied with the results; more than enough output for my needs with a reasonably even distribution of bass in the seating area. Will need to invest in better measuring equipment because my I-phone 5 with the Audiotools app is showing a roll off below 30hz, which should not be the case for this setup. Will post graphs after measuring with a UMIK1.

Once built it will be easy to test both by simply plugging a port.
Before deciding on that route model the port velocity with only the one port.

the driver is dual 8 ohm, so you can wire for 4 or 16 ohm net each driver.

because of different distances from the back and the front speakers to the listening position, having different distance/phase/level settings on them might help with final results.

Will the DVC385 really do 110fdb's at 15hz and still have any thing left for the mid-bass? I had always assumed that for that kind of output you would have to step up to at least the HO/HF15? If that sub will do 15hz up to 80hz with some good output then I may just have to order a few of them today, I was planning on order 2 U15's but could possibly go with 4 of the DVC385's instead.
