[QUOTE="Mike Smith, post: 98972, member: 152"] Re: Compression driver topology Greg, I think you might be looking for compression in the wrong places. In a typical compression driver with an annular phase plug, much of the compression and expansion are taking place in the concentric apertures of the phase plug; after the diaphragm and before the throat. If you look at a phase plug's cross section, it is a series of overlaid circular "horns." Having said that, a 1" diaphragm loading a 1.4" throat is kind of goofy. A lawn tractor pushing a hay wagon. Sounds like a combo of too many leftover parts to be used up, and marketing doublespeak. [/QUOTE]
