[QUOTE="Affray, post: 8789015, member: 685781"] Quick update I've been playing around with BassBox 6 Pro (very useful manual) and I have come up with the following design on it :) After allowing for displacement, the box volume is 100 litres or 3.531 cubic feet. Port is a round pipe with an internal diameter of 102mm (4-inch sh*t pipe in short as I have loads of it :D) at 1109mm long x 3 (to deal with the vent velocity) This gives me a tuning frequency of 25hz and an F3 of 23.61hz and this response.
