Hello everyone! Newbie here with a dumb question please! I’m currently running a 3 inch round port on same side of my American bass xd12 woofers ( two woofers with wall between, 2.15 cu ft each ) I like to run 4 inch port but I don’t have enough space to fit the woofer and the port together ! My questions is can I run 4 inch inside the box and connect with a 3-4 inch reducer ? Would it make any difference ? Btw right now the box are tune to 30 hertz , Thanks in advance
