This is more academic than anything else. If you ran an eminence 3015 (non-lf) full range so that you get a good bassic sound with some growl and natural break up, you would have a good sound that starts to beam at around 1khz and get worse. If you vertically stacked an 18sound 6nm410 over it, crossed over at say 1khz, would you gain the dispersion of the mid plus alittle more top end extension? Or would there still be some horizontal cancellation? I don't see why there would be. Just wondering.
