frogcase2002 Posted June 4, 2016 Report Share Posted June 4, 2016 Huh.. well that kind of screws up my whole understanding of 4th orders lol. i was under the impression that the sealed section would boost the low end and the ported side would extend the bandwidth. why would the opposite be true then? If 4th order bandpasses where just all around better enclosures everyone would have them . Really only see them when a regular ported is not possible. Usually just a regular ported is the better choice if designed and built right Clarion cz702 Ssa evil mids and tweeters ppi 900.4 2 zcon 18s Taramps 10k 3 big dekas 1 xs 3 runs of 4/0 and big 3 300+ amp ohio generator 155.7 on dash at 36 (peak) 152 at 25 Link to comment Share on other sites More sharing options...
Wasteland_Audio Posted June 4, 2016 Author Report Share Posted June 4, 2016 Which explains why every 4th i see is floor to ceiling, to get the sealed side as big as possible. and by the looks of it i would be severely disappointed with the low end output. So let me ask this then, if i were to build a flat ported wall like frog said earlier, would i see an increase in output with the reduction in cabin airspace?
