[QUOTE="Ivan Beaver, post: 16532, member: 30"] Re: Modeling my pet peeve-Arrayability concepts There are several aspects that determine how well particular loudspeakers will array. I will not go into detail-as that is pretty much a paper and a bit long for a forum post. A couple of ''bullet points''. Horn size. If the horns used are not large enough to provide pattern control down to a low enough freq so the drivers are close enougn together so they will sum without interference. Closeness of drivers in array configuration. When the cabinets are arrayed, the drivers need to be physically close together. In the perfect world the drivers would occupy the same physical space. But we can't do that-so getting them as close together as possible is the idea. The HF driver should be just short of touching the sides of the cabinet. The sides of the cabinets should be cut at 1/2 of the rated coverage. So a 60Â° cabinet should have the side cut at 30Â° each. If it is cut at less than than-then the HF driver will be far from the sides of the cabinet-and far away (in terms of wavelength) to the other cabinet. And of course the better the drivers inside a particular cabinet are aligned in time (this is not always physical and the phase response of the crossover has to be taken into account when considering alignment) helps to keep everything ''working together''. Here is a link that helps to describe some of those properties. The discussion about arraying is the 2nd part of the paper.
