The Fountek JP-3 and JP-2 would have about the same horizontal dispersion (very wide) capabilities. As the shorter ribbon the JP-3, would offer better vertical dispersion. Any ribbon will limit the vertical dispersion more than say a dome tweeter but the longer the ribbon the less vertical dispersion capabilities. The JP-2 would best be used in a line of tweeters so that the listener is covered for both sitting and standing listening.
