[QUOTE="Doxquzme, post: 8892502, member: 689267"] So, gross box volume is 4.27 if using .75" material. That port looks to about right as well, for 33hz. That said, I would bump the frequency up to around 35-36hz, 33 is a tad on the low side for that driver with an Fs of 41hz So drop the port length to around 23.5" should do it. You will never heart the difference but your 8's will thank you. That's a guess and you still need to model it to be sure. Good idea to set the subsonic (HP) filter on the amp to around 26-27 hz.
