Dayton Audio RS225-4 8" Reference Woofer 4 Ohm
Can I use this woofer in a 1.2 cu ft vented box? If yes, what is the port dimension and what is the expected frequency?
Yes this will work in that volume. I would recommend a 2.5" diameter, 8.5" long port for a tuning frequency of 32 Hz.

What sizes are the crimp terminals on the RS225?
This woofer uses 0.25" wide terminals.

Do you offer recone kits? I shredded the cone off of the phase plug. Spiders and leads intact.
Unfortunately we do not have any recone kits or parts available for these woofers.

WHAT SIZE PORT WOULD BE REQUIRED TO ACHIEVE THE 35HZ F3 SPECIFIED IN THE BASSBOX SUGGESTED VENTED BOX IN THE SPECS ABOVE. IT VARIES SLIGHTLY FROM THE 1,61 SQ. FT IN THE WOOFER SELECTION GUIDE, WITH 36HZ TUNING.
PER MATHEW AT P.E. TECH. THIS ALIGNMENT REQUIRES A 2.5 INCH X 6 INCH PORT. THANKS MATHEW.

If I wire two of these in parallel it will result in a 2 ohm load and a +6db gain in sensitivity. Then if I wire the above load in series to a third driver it will result in an overall load of 6ohm and no change in sensitivity, right?
Technically yes, but this is not how you wire three drivers together. The two in parallel will still receive twice the input power since they are wired to a 2 ohm load. The only way to properly wire three drivers together is either all in series or all in parallel.

I have the 8 ohm version of this woofer. I have 2 options in a 3-way setup. Place 4x RS225-8 into the same cabinet to have 8 ohm load, or use 2x RS225-8 wired in parallel, then RS225-4 wired in serial to have 8 ohm load. Which option is better?
