Frequency response, mass vs. inductance
I have a question. Someone on a message board I usually post on talked
about woofer speed. I assume what this translates to is frequency response (ie 1/time=frequency). He also posted a link, which I read: http://www.adireaudio.com/Files/Tech...ooferSpeed.pdf At the end of the page it shows a graph, with the frequency response of the speaker they used. To me, inductance would have little or no effect on a speaker unless, it were a midrange or a tweeter. And from this graph, mass still seems to dampen the signal more throught the frequency range than does the inductor, which is should I would think. (ie xl=2(pi)(f)(l)) When it does eventually does get to the higher end the inductor does not seem to cut the signal all that much. So what I would like to know is, if the inductance is the most important part, why not make it small, and increase your frequency response of the speaker? This probably would not effect a woofer all that much if the woofer was used for bass only or would it? I find it hard to believe that the mass of the cone has nothing to do with this at higher frequencies, which is why you cannot use a tweeter for a woofer. And by cutting down the inductance would also mean a smaller coil and maybe larger wire? Wouldn't that be a problem? |
