Stair Cardioid Subwoofer ArrayHi i just posted this article.http://soundforums.net/hub/2386-stair-cardioid-subwoofer-array.htmlAbstractThe advantages of cardioid sub configurations are well known, however they also have some drawbacks. Because of the nature of the arrays in their 2 in line and inverse stacked variations, cardioid systems reduce the acoustical pressure not only on the stage- but also at FOH, the most important area! This is in front of the array, where the audience is located. Level can be decreased by greater than 3-6 dB when compared to a simple mono cluster. This makes the technique unviable in situations where maximum SPL is needed. Measurements are presented to show and explain the problems here. Next we introduce a new way to create a cardioid array. In this new method, we achieve the same output levels as a mono cluster through most of the subwoofer’s bandwidth, while keeping the benefits of a cardioid configuration.Enjoy...
