[QUOTE="Brian Bolly, post: 64356, member: 32"] Re: First time Centre Subs Your spacing is a little too wide. Spacing between elements must be less than 240 degrees of the highest frequency being produced in order to get addition on axis and cancellation off axis. If that frequency is 100 Hz: (3.435m x 240/360) = 2.29m. Instead of using 2 blocks of 2 elements each, try using 4 spaced individually in the center plus the left and right. Also consider driving the center pair with one amp, the outer pair with another, and then the L/R with yet another, so you can do a delay arc the array as well. [/QUOTE]
