dual dx12 iso bandpass box

snappyjb67

hey, thanks for the help on setting up my component speakers, i think i have finally got them sounding great! i just started from zero again and turned all my eq's off and rewired each set. I turned off my loud setting on my head unit and reset the EQ and gain on my amp to were it should be and now they sound good! But now i have another question for you. I have been thinking about building another box for my subs.... i just want to experiment a little with some different designs. Fist off i downloaded one off this board , a dual dx12 iso bandpass box, and i had a couple questions about it: first, where do i mount the subs on this box? and where to i put the ports? also it says something about it needing to ports but only one has a flush end? I was also wanting to know how this box compares to the recommend .88 cu ft? I ultimately want the loudest, best sounding box i can get, thanks for all your help!!
