I'm building a ported enclosure for 1 12" EVL-12 2 ohm sub. The external dimensions are 24x15x19.66 and my net internal volume is 2.3ft³. I'm wondering if making my port area 35in² is too big? Or if that even matters. I'm new to this so any info. Would help. I think I attached a link to the design page for the box.
