there's an interactive version of the chart, too.

It's here: http://www.independentrecording.net/irn ... isplay.htm

The interactive version has a lot more inforamtion about the instruments, the harmonics and other bits... the graphic alone is around 20% of the value.

You would need a printer (make sure its a A4 printer)... print this out.

Fold it into fours lengthwise then slowly feed it into your CD slot...

Knowing what instrument and vocal frequency ranges fall between is a great way to set crossover points. For instance, male vocals as shown on the above chart go from 100 hz to around 2 khz for recoginition. Therefore, you want to try to plan your crossover points so that they don't interfere so much with whatever instruments/vocals you are trying to accurately reproduce. Also it is helpful in selecting drivers. For example, I listen to mostly hardcore/metal music and I love the double kick drums to be reproduced as tight and punchy as they can be with some authority. For my midbass drivers, I will use 8" or 10" drivers that can deliver that authority and "tight punchy" bass that I desire, as most 5" and 6" drivers can not deliver that type of authority at 50 hz to 70 hz. By knowing the frequency ranges of instruments and vocals, I will choose my drivers based on these frequencies as well as physical space limitations for the driver and enclosure.

Below is an article from CA&E where the author talks about driver selection based on the frequency ranges of instruments and vocalists. Now, in my opinion his install is over the top, but he brings up some valid points in driver selection, as well as driver placement. Also notice the comment about the "flat" RTA response that is measured, and how humans perceive music in a different manner than the RTA. I remember Greg Kitching making a comment about how a tuned to flat system sounds dull, and this explains why. That is why after using an RTA it is always best to tune by listening.
