So your box is 3.4cu/ft? My guess is around 45-50sq inches of port opening for 3.4-3.5cu/ft of air space. Although I have heard that Power Acoustik speakers like big boxes, so you could possibly go bigger than that. Length will be dependent on tuning preference.

Yo yo you need some help bro?

Never designed a box for them, but we had a 12 in a nice sized box, bet these would be the same.
