[QUOTE="Brian Bolly, post: 64385, member: 32"] Re: First time Centre Subs There's two problems here: First: Your models show (presumably) all subs are the same, when in reality they will not be. So if the subs have different output, different frequency response, etc., all bets are off. Same with the inner 4 that are being driven off 2 different types of amplifiers - if one pair is outrunning the other, this will not hold together. Basically, all subs need to be handicapped to match the lowest common denominator of performance - output, frequency response, delay, etc. And if it's two different types of boxes (i.e. - horn loaded vs front loaded), this will be even more difficult to achieve. Second, the L/R subs are coupled, whereas the rest are not. Reduce the L/R subs to -6 dB in comparison to the center subs - again, this will likely differ in practice since they are different from the center subs. You also may try to shorten the delay times to something like 0/0.5/1 ms from center to outer. Also, your spacing from the L/R sub to the outermost sub in the center block looks greater than 2.29m.
