My car is a 91 camaro. It has very limited space in the hatch. To get the most out of the space, a box has to be made in a very odd shape. So far all my design ideas have been centered around a sealed enclosure because I'm pretty sure that I want a "flat" response from what I've been reading. I've read that there are ways to get a flat response out of a ported enclosure, but supposedly it has to be done just right. So my question is: Given the general shape of the box in the picture below, can I design a ported enclosure that will not sound "boomy", and be able to keep up with sounds like really fast double bass drums, etc.? ...Or should I stick with sealed?
This is a view from the right side of the car. The box will be roughly 41" wide. The dimensions are shown just as a reference, not for calculation. It will hold two FI-Q 12's. I've done some rough calculations already and I'm quite sure I can meet the maximum suggested volume of 2.5cuft per sub, so that is not a concern. What I am concerned about is whether or not the shape is too cumbersome to bother with a ported design.
