Good to see you here, Jim. In a big way, your dedication to the DIY community is what prompted the formation of this Array Speakers forum. I don't know of any other discussion boards that are specifically meant for arrays, and some thought that was a glaring omission. Array speakers are an entirely different breed than single driver speakers or horns, and lumping them in with pro sound didn't seem quite right either. So the Array Speakers forum was formed as a separate message board instead.I don't know if you noticed John MacBain's posts below, but he referenced your work in them. One is called "line arrays questions and stuff" and the other is "Fresnel and fibonacci line array systems". Looks to me like these discussions are right up your alley.
