I have 8 double 18 yamaha cw-218's running each with a qsc 2402 in bridge mono. The cabs are rated at 1200 watts each and are subwoofers. for mid range I am using JBL JRX double 15's with qsc 3402 in stereo to a set of two speakers for a total of 8 JBL JRX. For horns I use JBL 2420 1 inch horns. I would like to know what is the best settings for I should use to recieve the optimum output for my entire system espsecially the bass. I would like a heavy chest pumping but round bassline how can I achieve that. As of now the system sounds very very good. It is a very clean system I just want more. What settings should I use for crossover such as the filters and is there any delay I should use.
