[QUOTE="rickymac21, post: 8157083, member: 604748"] Well I finally decided to go with the 4th order bandpass for my trunk install... Basically I have the cu ft for both sealed and ported chamber... Now I just need help deciding on the two options shown below. This first picture is a TOP view looking down into the box... The sub and port are firing in the same direction which if in the trunk would be into the cabin of the car... This was my first idea but after reading apparently having the port right in front of the sub like this isn't a good idea as it'll mess with performance output ... Any thoughts on this one??

In this design the sealed section has the sub firing up, while the port direction stays the same as the first desing (port fires into cabin)... [URL="http://s1272.photobucket.com/user/rwm41991/media/4thorder2_zpsf0265679.jpg.html"][IMG]http://i1272.photobucket.com/albums/y400/rwm41991/4thorder2_zpsf0265679.jpg[/IMG][/URL] Both boxes are would have the same dimensions externally, but the sealed chamber changes obviously. Regardless, the number of cubes per chamber wouldn't fluctuate between design, nor would the tuning. The only change is the sub firing direction and my question is which is going to be better?
