what do you all think about a 6.75" round port-no flares- for a 15" in a 3.6cube box. box will probably house a Xcon, BL, or HDC3 getting bout 1800w before rise and all. not all that concerned about minor port noise as it will be in my trunk, but i am looking for max output as this box will have interchangable ports- one being 44Hz for #s and that would be the most important outcome of this box.
Im thinking that if the port extends beyond the front of the box there will be less resistance- that make sense?
thanks for any help
