[QUOTE="mlstrass, post: 3319161, member: 569126"] VERY interesting, might have to try that some time. I have also wondered what the air inside actually does as the sub is pushing the majority of the air until you get very near/at tuning which is not very often on a low tuned daily box and most music normally listened to. Could be why the smoke just dissipates. Perhaps doing the smoke test and playing tones at/below tuning might offer more insight. I don't see how the pick up bed analogy relates though. I understand air trapped inside the bed "forces" air to flow over the bed, but there's no air flowing over the air trapped inside a box, so we're actually dealing with the air in the bed if using the mythbusters test. Can you explain more? I "assume" that the air pulses in/out of the port, but have no idea how far the air travels in/out and how much air from the box is actually expelled each time. Going off of that knowledge or lack of I still feel that a 45" in the corner at the back of the port is beneficial as at some time or another air will be making that bend and I'd prefer it to be a 45 [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] Any more thoughts as this is rather interesting???
