Hm, Yes, I kind of forgot the idea of multiple compression drivers blowing into the same throat. I never was too warm to it but I do admit that it would minimize the length of the horn. For sure the right solution would be to make compression driver with let say the same 4” throat. This is kind of tricky as this driver would have at least 6” diaphragm and it is problematic. By using a multiple compression drivers we get rid of the problem associated with bending of super light metal diaphragm but we do pick up problems with individual driver integration, differences in exertions, curvature of the knees that form the multiple compression drivers assembly and the rest problem, not considering the price of cause. I do not know if the use of multiple compression drivers would be preferable instead of use of one larger compression drivers. I would certainly bet for use one larger driver. The biggest problem is not placing of non-educated bet but an absence of large compression driver with resonance frequency of sub 70Hz. There is a 4” exit compression driver - 4M but they use a second suspension in the middle of the driver to keep diaphragm firm. Because of this or because of any other reasons the driver sounds horribly and shall not be used for anything else then to make public speeches during those RNC conventions.
