[QUOTE="Moble Enclosurs, post: 7673490, member: 634917"] You can just throw numbers out and expect superior results. but what i recommend in this case is to listen to McCabe had to say. Same drivers and he went through quite a bit of changing before something was desirable. That kind of experience is fully necessary when dealing with bandpasses rather than throwing out numbers and going with a generic 2:1 ratio. But for informational purposes, 200sqin can work well if the design allows it to. But the room needed may be quite large. Not to say that certain more complex designs can be scaled but i would not recommend using just a numbered recommendation with the full understanding of the design as a whole. The great thing about 4th orders, is phase control can be less important than in a combined phase design idea, so generally, if you want to stick with just numbers for designing a forth, it will work......just might not be what you want in the end. Either way, good luck on the build and i hope it works for you! Keep us updated! By using a designer, you will get much better results than just, "try this.....". [/QUOTE]
