Dayton Audio SD270A-88 10" DVC Subwoofer
Internal dimensions for sealed boxes are 9.5 x 12 x 17. I am getting 1.122 ft3. Will this work with this sub? Should I add any insulation?
That volume will work with this sub. We recommend about a half pound of stuffing per cubic foot of airspace.

Can a lower frequency be obtained in a different sized sealed box? Is the f3 suggestion the best way to go and do I need to subtract the subwoofers mass from the f3? Also is the f3 suggestion for the 12" version accurate because it is a higher fs?
You can achieve a lower Q by putting this in a larger enclosure which will help the low end a little but not much. The volume online is total and is what the box needs to be built to. Yes the F3 of the 12 is accurate.

Is this the same driver as SD270-88 sans shielding? The reason I'm asking is that I currently use two SD270-88 per side in an open baffle, and they sound great. But I want two more per side for lower excursion and higher output capability.
Yes these drivers are virtually identical in terms of performance. The overall sensitivity dropped a touch without the bucking magnet to aid the motor strength but this should not be a deal breaker.

I've had a pair of these for a few years now. They perform great. I'm lookin to do a diy and was thinkin of the dayton designer 5" and dayton 1 1/8" silk tweet. Seein the subs fs so low; would it work well in a vented size box but without the port?
You will have to elaborate on "vented sized box" since this could mean about anything. These will work pretty well in either type enclosure but the volume of the box will determine how low and loud they will play.

What would the volume of the box need to be if I plan on using the matching 10" passive radiator with this sub? Also would this sub function well in a down firing configuration?
The recommended volume for this woofer and the matching PR would be 3.8 cubic feet with no weight added to the PR. This provides an F3 of 33 Hz and a tuning frequency of about 28 Hz.

Looking to run 16 of these into a 1 ohm load is this possible?
Yes this would be possible. You will need four sets of four each wired to 4 ohms, then all four sets wired together in parallel.
