kind of hard to put these subs in a design program without specs.
had to do the push the cone down and pull it up by hand test, put a battery to it and see how far it moved up test, stick a screwdriver to the magnet test, play it free air on sweeps with my hand on the cone test. that was just foreplay.
it came down to building the box for a starting point and adjusting for what i wanted it to do. im pretty happy with them. knowing i have a lot more i can get out of my system is what excites me.
