I think this speaker has too little xmax to be very useful, but I am no expert. I modeled it in a 20" cube both sealed and ported and in a sealed box you get a -3db of about 60 Hz and in a vented box you get about 25 Hz at -3db. You would need a high pass filter for sure on the vented box at about 24 Hz and you hit xmax in the sealed box around 32 Hz.
This is the response curve:
(green is ported and blue is sealed)
And this is cone displacement:
(same colors)
