When setting the amp/sub as far as crossover is concerned, how do you determine what crossover frequency to use, whether to use LARGE or SMALL and whether if using LARGE would you have the sub on LFE only or would you have LFE + Main? As far as my limited understanding of "Large" vs "Small" speaker and subs are concerned, this is what I make of the options available: AFAICT the setting of the crossover is crucial in any set up, but much depends on the performance/capabilities of the speakers WRT to producing a flat enough response to the crossover frequency. Are there any magic formulae / guidelines as to best determine the optimum? What do you have set up on yours? BTW, note my updated new sig....... 1 x SVS sub in the kit. Nice one Rob!!
