Regarding the 1800watts/box rating. What frequency and what type of hpf?

The formula used to calculate this rating uses the FS of the system as it's the point of greatest xmax.  High pass filter is not a concern as cone movement is reduced with higher frequencies.

Your referring to a Low pass filter.

 

I am talking about a "subsonic" filter.

you would use a subsonic filter as normal to limit unloading.

How would 2 of the 12s do with an 8 inch round port? Tuned in the low 30s.

ideally you would want a 9.7 inch diameter port for two 12s tuned to 30 hz.  However you may not "hear" any port noise.  If you have the space build a port with 75 square inches of surface area.
