[QUOTE="Farside, post: 431011, member: 554476"] Hey thanks again, I've decided to use a Vb=1.68 ft^3 box (internal volume not including sub & port displacement, I assume thats what Vb is) with a 4" port 22" long Tuned to 28.7 Hz. Still cant figure out that dam minimum port diameter calculation :blow_up: , but oh well 4" sounds resonable. My question is now that I have all my dimensions to work with, [B]what is the minimum distance that the port can be placed to a wall inside the box and the Sub? [/B] Is there a minimum distance that the sub must be from the walls as well or is this just a practical measure? [/QUOTE]
