Based on previous post on this subject I decided to try and set up at aux fed subs using available crossovers and my sound craft so compact. I'm using dbx drive rack pa on tops and dbx 223 on subs. Routing through aux 14 on sound craft. Set crossover on 223 at 87hz and driverack at 90hz. Other than plating programmed music I have not used live yet. Given the different crossovers am I creating more issuses than solving?
