[QUOTE="ballstothewall, post: 1722353, member: 559563"] According to a study done in '51 by a Harry Olson, he found out the the difference in variations in accordance with the box sizes... [I](all values are +- variations in SPL levels) [/I] Sphere: .5dB Cube: 5dB Beveled Cube: 1.5dB Rectangle: 3dB Beveled Rectangle: 1.5dB Cylinder: 2dB "The rectangluar loudspeaker enclosure is, however, often judged less than optimal as a radiating surface because of edge diffraction issues and also less than optimal regarding internal standing wave modes." I am pulling this info outa my Loudspeaker Design Cookbook, so take it for what its worth... [/QUOTE]
