diegoclass2010 Posted January 9, 2014 Report Posted January 9, 2014 mmmmm it can go both ways... but for sure a 4th order is more efficient you can get away with less power.

SlamminBeats Posted January 9, 2014 Report Posted January 9, 2014 in theory it is supposed to be ?? maybe across a bigger bandwith?
mrd6 Posted January 9, 2014 Report Posted January 9, 2014 I think in theory, a well designed larger ratio 4th should be louder on the same clamped power...but we all know it's not that simple and that may not always hold true in practice.

IH8PunkRok Posted January 9, 2014 Report Posted January 9, 2014 I read that each order is supposed to gain three db. I may have heard it from my extreme car guys. Either way that is what I have read or been told. Also saying a fourth has a larger bandwidth is laughable. Plot one out and look. They are louder so the wide bandwidth is perceived not true. It's like saying ported has a wider bandwidth than sealed. It just isn't true. -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build
Krakin Posted January 9, 2014 Report Posted January 9, 2014 I read that each order is supposed to gain three db. I may have heard it from my extreme car guys. Would that account that a vented enclosure is still a 4th order? Just not a bandpass. Edit: for the 3 db gains Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.
