I went out of my way to explain the crossover points... silly people Why kill specific bandwidths? Several reasons. For me (NOT YOU) it is fun to show people who aren't as knowledgable as you what the different drivers do and what different frequencies are. Second, because I (NOT YOU) enjoy listening to certain things and not others sometimes. Sometimes I like to hear just the depths in the vocals for something, or hear just the treble in a certain part of a song. It is nice to be able to isolate it to check something out. Furthermore, it helps a lot to isolate specific drivers at certain times. I hear something in a song that sounds odd or out of place, I back up, kill the other drivers, replay. If it's in an overlapping region, I back up again, try it with the other driver. I (NOT YOU)_ find it very useful. Thanks for the encouragements guys, soon as I get the 1st driver (those pics I posted were what I received from the seller) I will take some more pics of it then free air it on an EP4000 and of course make too many vids of that as well
