[QUOTE="BrianChia, post: 3012402, member: 576132"] I don't want to argue any more but the water analogy is invalid. Say you turn this box on it's side and flow water through the port with the a front firing alignment. The box is the exact same one which OP built. Then find an equivalent labyrinth slot ported box, also front firing. Now take a garden hose to both ports. Now which one flows better? The OP's box / rpfuror's design now has gravity to it's advantage and will flow better than the labyrinth port. You can't use water as an example because it's 3rd axis of travel is bound by gravity. Air is not significantly affected by gravity which is why we can build upwards firing ports and speakers. As I've said before, this bend is no different than a 90 degree bend in a "labyrinth" port. The second you build a bend into ANY port (labyrinth or otherwise), airflow is NO LONGER in one continuous direction. Once air reaches the end of a straight segment it hits an obstruction and is forced into redirection by compression in both designs. The only practical way to maintain single direction continuous flow is a tubular port with no bends. [/QUOTE]
