again, my question about live music.
the original post for cabinets for 2268 drivers mentioned that there were only some days with live music and other nights there were dj's..
this was really interesting to me..
so I asked where anyone thought in live music (mixed differently) than recorded music, did max-excursion occur?
I didn't state a bunch of facts.. I asked a question.
can anyone answer it? or is it slam fest for asking a question?
( NO STUPID IT COULD HAVE BEEN A TRIGGER )
??????? what? how does that connnect to my question?
its like people want to read into my thinking and find something wrong with it.. without attempting to even talk about the original question
yeah thanks.. do you see my point
there is more to my question as to why it is even a question.
everyone knows amps have more impulse power than continuous power. or do they? anyhow, considering a kick is more of an impulse than a sustained track or bass-line, in my mind, that meant that the kick had an even higher chance of creating max-excursion (as opposed to a bass line)
also, the instrumentation used to measure this for the fancy plots could be using data from the amp-- I don't do those plots so I don't know. but could it be possible that they calculate those plots based on signal used to drive the amplifier.. however, is this the same as the actual physical motion of the driver? or is it based on voltages?
or current drawn?
how much of that energy was converted to heat?
how much of the actual physical woofer motion mimicked the chart?
my question also has more purpose: the answer may help the original poster decide which drivers to use in his boxes.
what if the other woofers made more excursion for a sine wave but as someone said, the excursion exceeded their specs xmax?
well, then, wouldn't this mean that physical damage could occur during a live mix?
in JBL's case, they may have a cone which is physically made to take more physical abuse than any of the electrical abuse which is ever thrown at it.. in other words, perhaps the driver is designed to operate with a max voltage, max current which will never achieve xmax on purpose-- for longevity reasons.
Also, if you over design the cone physically, you might lose some of the efficiency but they may be more capable of withstanding extended exposure to sunlight (could be helpful for anyone else reading this thread if answered).
I actually dont know the answer.. I'm just thinking about it. I'd like to know. but I'm thinking in practical terms, if I knew the answer to where maximum excursion occured, I could use that information to decide if they actually had made the cone more durable than necessary. this could encourage me to buy more of them or not.. or it could help me decide how maybe a friends drivers were actually damaged or if someone asks me.. 'hey, do you think this setup is ok?' it may help me give them advice of what to watch out for.. say someone asks.. where do I put my limiter on this amp which is more powerful than the spec.. all kinds of reasons for asking this question.
