[QUOTE="tommyk90, post: 6738476, member: 545293"] That is not true at all. How an enclosure will flow air in the enclosure is dependent on the vehicle itself as well as the box. Dropping an enclosure into a trunk effectively uses the trunk as another enclosure, basically making a 6th order bandpass of sorts. How the trunk is designed, the dimensions, airflow around the box, and so forth, can determine how/how much air can flow in and out of the box. Pressure spots, excursion, port loading, etc. can all occur on different levels depending on the final install. The box is not the only factor here. Depending on the length of the port, it's orientation, and WHERE that port fires in to (side walls, how close, etc.), the whole performance of the box can drastically change. If you don't understand this, then I can't really help you any more. Though yes, if you can make airflow inside the box as smooth and non-turbulent as possible there is the potential for gains, you won't know how much, if any at all, will be perceived in the actual environment. You can spend hours testing the aerodynamics of an enclosure only to not notice any type of gain (whether it be output or SQ) once the box is actually used. Regardless, all your fancy tests do what, MAYBE give marginal gains in a realistic environment? Couldn't your time be better spent? I understand that you are passionate about the hobby, but I feel that you are wasting your time by doing such complicated tests when in reality you have no idea how each box will perform in each type (and model, not all trunk cars will perform the same) of vehicle. In the picture you posted, I see absolutely nothing that would dictate your enclosures somehow produce a smoother airflow than any other slot ported box. In a few instances I can see how some of your boxes can cause uneven pressure spots due to sub and port end positioning. Like I said before, if you're trying to win over people with experience and testing, then you're gonna have to do a little better than just SAYING you're doing these tests. We need results. [/QUOTE]
