So my dad reworked the port, keeping the same
tuning. He did it more for appearance than I guess, he's planning on covering it with a cloth to match the Starks and eventually put this system in the house although I think he is hesitant due to having solid tunes in the shop/man cave.
Im looking at doing this sub build for my uncle. He is who got my father and later myself into audio. He Runs his home studio on a single PL 400. I recently scored him an Ashly FET2000? I think. It's got some nuts and I'm thinking of building him 2 of these subs to supplement his low frequency.
