That rule should be dead along with the floppy disk.

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.

Still pondering on that his sa15 wont like less port per cube though,especially at subsonic frequencies,unless that is he has too much port per cube to begin with.

Krakin Posted September 23, 2014 Report Share Posted September 23, 2014 You're not understanding that the "per cube" is the part that needs to be completely and utterly left off of any sentence that has any relevance to port area. Port are is not in the least bit determined by the volume of the enclosure. Also port area "suggested" is determined partly on the tuning frequency and will have the highest velocity at the tuning frequency. If the enclosure is tuned at 45 hz the maximum velocity will be at 45 hz, not 20 or. Another thing you said is subsonic. There is not a single sound that can travel below the speed of sound.

Once again, thank you. I corrected myself aready,stupid error. "Square inches per cubic foot" The subsonic i was referring to was actually "sub·son·ic" ...(non audible frequencies). Which im probably wrong anyways since it doesnt get non-audible untill the low 20's. Link to comment Share on other sites More sharing options...
