interesting question on air movement/hairtricks


Recommended Posts

Posted

is it the decibals that decide how violent a hairtrick is? Like will 10 18s doing a 155 and 4 18s doing a 155 have the same air movement? Or is it flat out, cone area moves the most air

Cone area is a nice shortcut to nice hairtricks, Also depends if it's a wall vs no wall setup. And if the 10 18s are doing a 155 at mid 20hz or so and the 4 at a higher Hz like 40+ the 10 18"s should be more violent. All install dependant really.

Tuning, port size, cone area, driver parameters, port position, port shape, what note is being played, and lots more.

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.

the 2 cars im thinking of are JP and that guy justin from ssa and they both do around high 150s on music, justin having a lot less cone area and power but gives a sick nasty hairtricks atleast as good as JP so im thinking, what could it be that lets that guy justin do hairtricks on atleast the same level of JP having a fraction of the power and cone area? But i guess install dependent is the best answer and really only answer

Justin is playing a lot lower frequency than jp, his box is also tuned low so that can help move air

Same thing with mine, does mean hairtricks compared to higher powered/more subs
