You sir, are a f uck tard.... that is to say you are retarded in concept and are also f ucking up with your arrogence... you think of yourself as a mechanical engineering technician yet you fail to grasp a concept a 6th grader should understand ???
Displacement is equal to area multiplied by travel... not surface area by travel... I'm sure getting past this hickup will suit you well in your engineering endevours... //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

That is an excellent description right there (minus the shots). What I saw in the seminar was *why* it was like that...

HAHAHAHA wow that was the dumbest thing i've heard in a long time... area is surface area in this case, because the surface area were talking about is whats actually doing the displacement you moron. wow i was in such a bad mood thanks for the laugh lol

lmfao...
that was actually the point I was going to make (the same as audioholic) but for some reason I couldn't think of how to word it, or demonstrate it, which he just did.

and no shit they make dome speakers...because it has a different SOUND, not because its louder...

WHO SAID ANYTHING ABOUT LOUDER, I HAVE NEVER ONCE MENTIONED THE CONE OR DOME BEING RELEVENT IN OUTPUT. you need to learn to both read and do geometry

See those divisions? Now imagine we keep dividing until we have divided every single of the smallest measurement you can think of.

Now, are you telling me you move more air by having those tiny lines of air movement staggered than if they were all level with eachother?

Geez.. enough already

So why then do you propose we need to know the actual area of the surface of the radiating diaphragm?

You said it displaces more air. More air displacement = more output. It does NOT displace more air.

No one is arguing that the actual surface area of the entire cone is the same regardless of depth, we're talking about displacement...

Listen co ck head... I'm sure you think you know it all.... but maybe you should set your bloated ego aside and think for second....

If you don't believe Audioholic maybe you should get a second opinion from a physics professor; or a 10year old who knows shit from beans... //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

yes thats exactly what im telling you...

all insults and jokes aside im going to try to explain it how i can see it in my head and how i did the 90 degree right triangle thing earlier

say you have a 90degree triangle and inch wide (up and down like the pic) and cut it right down the middle and lay it flat then you take the right piece and flip it over so they join perfectly, you now have a long flat piece that is the lenth of the 2 legs of the triangle, vs just the length of the hypotenuse (which would be the diameter of the circle)

in basic theory because the triangle is longer but is moving the same amount linearly it will displace more volume because its area is greater to begin with

make sense?

You know there is no such thing as 'enough' //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

you need to read the entire thread, someone mentioned earlier the greater the angle of the cone the more cancelation you have, so even tho you do have MORE DISPLACEMENT (because you do) doesn't necessarily mean its louder... which is why i never argued it was. if i was louder everyone would do it

i never said we did... the person who started the thread labeled it "cone area calculator" but was actually calculating the area of a circle not a cone, i corrected this fact and all hell broke loose. after we established that yes a cone has more area i was told a cone and a circle moving the same distance has the same volume which is only true if the distance is greater than depth of the cone which you proved, thats established, but a subwoofers excursion rarely exceeds the length of the depth of the cone.

We all passed 2nd grade geometry...

You're forgetting the cone only moves up and down, the third dimension doesn't make a difference...and if you really thought about my example in detail and imagine each individual microscopic subdivision, and then imagine we just shift the ones in the middle UP so that its even, how does that make any difference in how much air is displaced?

Ok, that's it. This thread is now Sagetted
