I'm a physicist, I'm quite familiar with it. "complete a full cycle" is fine. By "compression to refraction" you mean 'rarefaction', which is a decrease in density, and compression to rarefaction would only be a half-cycle.
Your earlier statement: "so you wont hear it at its loudest unless your 10 feet away" would only apply to a situation in which there is a standing wave with a wavelength of 10 feet (a wall n10+5 feet away where n is a positive integer, for instance). Otherwise, the loudest point would be at the source. For a point source, the intensity drops as 1/r^2, while the sound pressure decreases as 1/r. look it up.
I'm not talking about wierd situations in rooms with objects and a sub on the floor, blah blah blah, and perhaps it's a difference in context that is leading to a misunderstanding. I'm not versed on room treatment and behavior like some here are, which is why I wouldn't attempt to discuss such specific scenarios. As many have taken the time to educate me, I like to return the favor where I can.
If you'd like to discuss anything further, drop me a PM, I'm beginning to feel like a threadjacker.

wtf are you talking about? i was pointing out where the misconception that you were pointing out comes from, not challenging you to some duel of mental manhood, genious.
and by the way, you're wrong about 2 things. compression to rarefaction (yes thank you for correcting my spelling) is a full cycle of a sound wave. and 60hz wont be loudest at the source, it will be loudest 10-12feet away, which is about the distance it takes for 60hz to fully develop. this is why cars will sound so loud coming down the street..
and theres nothing wrong with saying develop instead of "complete a full cycle", gtfo you highhorse fukin robot monkey. |
Nice thread edit?
Honestly, why do you feel the need to attack me directly. "fuckin robot monkey" ? Really? Honestly, why? Of course this isn't some "duel of mental manhood." I'm sorry that you're used to crap like that happening, seeing as how it's the internet and all. My intentions are not and never have been anything like that. Read my PM that I sent before you edited with the BS personal attacks. I was hoping to discuss it further with you there.
(I'm taking the perspective of maximum compression, to maximum rarefaction and then BACK to maximum compression for a full cycle. Symantics. Whatever.)
This entire conversation should have never taken place, and I apologize for how off topic it is.

To put it more clearly, the Inverse square law.
Sound intensity is inversely proportional to square of distance.
For the doubling of distance from the point of origin, the SPL drops by 6 dB.
One thing to note is that the Inverse Square Law applies to point-and-shoot speakers.
Line array speakers are another story.

Nice No Left Turn. Looks comfortable. How about you rotate the monitors a bit inward facing you. Hopefully this picture will get this thread going on again for what it's intended for.

The monitors are designed to point straight and not angled towards one's ears/head. I know, pretty much everything about the design of the monitors are pretty odd, but it all somehow works the way it's supposed to. The manual even specifically says to have them pointing straight and they actually do sound really weird if you angle them inwards.
3F05Q:
The M-Audio Xponent is treating me very well. Got the jog wheels adjusted to feel just like the pioneers so DJ'ing feels extremely normal. The software itself is kind of irritating. Though, it's functionality is extremely powerful and easy to use, the GUI is absolutely wretched and the file browser is only a few rows in size. If you don't have decks and just need a setup at home for practice, it's definitely worth it.
