[QUOTE="Jeffdachef, post: 8544756, member: 650438"] You can step down to a 3 inch port 16 inches long if you want it musical but as of now, torres calculator and your results dont lie, you built a box not properly tuned to deep lows. Your port per cube is on the higher side and your airspace is on the low side. This is basically a burp box format. If you want to keep the 4 inch port, you need much more airspace. If you want to keep the same box, you need a smaller port. It cant be 1.35 cubes after displacement, thats completely impossible because your port itself takes up ~ 0.25 cubes of displacement(assuming your port thickness is extremely low) and your net airspace is 1.44. Not sure what you are using to calculate but you might want to switch programs. 2x2x3.14x29= 364.24/1728 = .21 thats with no port thickness accounted for. plus .16 from subs. [/QUOTE]
