[QUOTE="Moble Enclosurs, post: 7603108, member: 634917"] You cannot expect much more out of it at this point for a sealed enclosure because it is not as efficient in a sealed than ported, unless you are talking now that you have ported it since then. Did you port it yet? And did you make sure the divider was sealed correctly to control the volume compression? There is a lot that can be done still, but you have not explored the other options yet. Also, You cannot take the response from one vehicle and compare it effectively to another as it will have a different effect on the response also, so just because it was better in one vehicle does not mean it will be in another......even in a different size box......since it is the type of box that will make the difference. Does that help a little? Even though, yes, the LF response can have, as mentioned, a constant, there will exist in some vehicles points of cabin loss (= 0dB gain) at even low frequencies below the cabin's 1st and second order resonances. This can occur due to placement, not direction. Where the box is located will have a huge effect on the response and it seems that where it is....is just not working for you. Try putting it in different locations (temporarily) such as the back seat(if you have one), in the corner, as much as possible, and other locations until you can possibly hear some sort of difference. Without the measurements of the vehicle and other factors, I cannot give you any advice on placement yet, unless a design is to be purchased for calculations, but try those things and again, port that mofo, lol. I really hope that you find some changes that help soon. [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] [/QUOTE]
