[QUOTE="Beatin', post: 8804371, member: 646085"] i put the parameters in winisd. Actually, the box may be too big. 3.7cu/ft net with a 7x6.25 port dimension which equals 43.75in/sq. It is 22.25in long tuned to 33.95hz. compared to 4 sa10's in a 3.7cu/ft sealed box, the ported box is VERY peaky. At around 35hz you have well over 30-40ms group delay. Within 5hz, from 35 to 40hz there's a 3db difference. The box is so big for these subs, this is a rare case where I would attempt a 6th order build instead. 😵 [/QUOTE]
