[QUOTE="Kippo, post: 1441202, member: 10096"] hi193, u said that above 100hz, class D amp is teruk. but class D amp has low pass filter up to 250hz. but why u said above 100hz? there must be a reason for it. on subsonic filter, u said only a few sub can handle 20hz~25hz. Is it due to sub design? and u said that the sub-woofer can only handle eg. above 40hz and this is where sub-sonic is required. But why that sub can handle only above 40hz? what is the factor?
