Posted April 24, 200718 yr when people talk about tuning their ports to 33HZ and stuff is that based on the size of the port. Also could i run 2 12" SSD subs on a hifonics amp putttin out 1500RMS or should i get one that puts out 2000RMS.
April 24, 200718 yr Port tuning is determined by the size of the enclosure, the port area and the port length. The calculations are here - link. The formulas are written for a round port. If you are using a slot port, just convert the port area to the equivalent sized round port.-Robert
