bigger speaker, bigger sound. smaller speaker, smaller sound.


The way i understand it, the bigger the sound wave, the slower it moves because it cannot displace air molecules fast enough.

 

but thats not even almost recognizeable by humans, and even by many machines. that is actually a recent discovery because it is so small.

 

Well I can notice it. I dont know what you mean by recent discovery but our manuals at the company I used to work for in 95 expressed this.

I mean sure alot of people wouldnt even notice it. They also wouldnt notice how crap kicker solobarics are or even be able to say why.

But theres a reason for it all, if you have the critical listening skills needed to define what is good and what is crap.

I mean surely we can all tell the difference between a set of Bostons when compared to a set of walmart speakers?

 

but it isnt possible to measure the difference by anything that is organic. audible frequencies have an affect on sound velocity that HAVE to be measured by insanely small scientific notations. there is no way any machine less than a thousand dollars, let alone a human can pick that out.

 

a 2 channel oscilliscope($400-$3000) or spectrum analyzer($10,000-$75,000) and a microphone can read it.

Set up an experiment-

set the microphone equal distances from the speakers

hook up an oscilliscope or spectrum analyzer to the RCA inputs (control)

hook up an oscilliscope or spectrum analyzer to the microphone (test)

set the B-delay to compensate for the speed of sound

freeze the display.



I have no idea what the reading would be, but it would probly display the lower freqs slightly delayed from the tweet.

 

the delay would be so small that any normal experimental deviation in setting up the distances between the speakers and mic would null the results. like, exactly where the sound is propagating from the speaker, whether its at the very front or middle of the cone.

 

You could compensate for that by taking the measurements at 10FT, or using a flat-cone woofer. Either way, at 10 FT, it's a pretty small difference. You would apply a +- 0.0069 (1" over 10FT) tollerence to any reading taken.
