There have been several posts about which sub is better for music and how to set up a sub so that it integrates more seamlessly with the main speakers. I recall a while ago coming across some information about the frequency range of rock music instruments. What suprised me was that the bass guitar and bass drum do not extend down that low in the frequency range. Unfortunately I can't remember the numbers and that's the purpose of my post. Does anyone have a link to a chart with frequency ranges of instruments? It would be very helpful, because I think many of us are assuming these instruments have a lower range than they actually do.
