Six 8mm-screw (M8) and two 6mm-screw (M6) suspension points provided for flexible rigging. That is, if you orient a squawker horn so that it is mounted with an up and down, rather than left to right, long axis, you will get BETTER horizontal dispersion and NARROWER vertical dispersion. The dispersion patterns of speakers is very rarely symmetrical in both vertical and horizontal planes due, not to the dispersion of the individual drivers but, to the interaction of the radiation from the drivers around their crossover points. Some lines, like IJN BB, already have greater vertical dispersion than others, so it's already being used as a flavor and balancing factor. In fact, the more identical drivers a loudspeaker has, the more it behaves like a line source instead of a point source. This is stating the nominal angle of high frequency dispersion in the horizontal and vertical plane. The concept was invented by Lincoln Walsh in in 1957 but the patents are now owned by Ohm. This is logical for cinemas but it runs contrary to common practices in domestic listening rooms and home theaters in which.
