Port area. what does it affect?


Recommended Posts

Impedance doesn't change with power other than the heating of the voice coil causing the impedance to increase slightly. Exceptions to this would be there is so much power that part of the voice coil is being driven out of the strongest part of the magnetic field. A box that starts flexing or leaking with added power. Stuff like that

sooooo

the imsg, just giving out what it does, will show you a resistive, actual load....

hell thats why i used it...

the AMM1 is cool for when you burp, or whatever.... shows real time power, load,....

hell ive done that 400 times also......

showed me my reactive load, power applied in dyno, real time or what ever..... .. trust me.. i get it.

kyblack76 - blows minds....

What impedance do you wire your amps at?

In that video you can see..

i start at .35, .. thats why it only goes up... it cant go down.. right?

also, watch the impedance vs freq.....

lets all learn something here.... .. im down

NOW, i at .7 dcr because i couldnt keep my boards playing.... unless i "tricked" em..

It can go down.

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.

Fine then.

It can happen, but whatever.

Im trying to make you think clear, but you will not do it.

You keep trying to compare this video of all woofers wired together at .35 to each woofer wired at .7, and still think you have a rise to 1.5, when actually your starting dcr is .7 and your rise is going to be someplace in the mid 2s per amp due to the higher dcr unlike the dcr in this video you posted.

But you cant seem to wrap your head around that.
