Hi @iamasif
It depends on how good your sub is. It sounds to me like you have a good one if your preset 2 is working well. Preset 2 is sending more of the lowest frequencies to the subwoofer. 50hz is reasonable although the DI's should be strong down to 30 hz or so. I would only suggest trying preset 2 with a 40 hz or even 35hz crossover on the DI's and seeing if that's an improvement.
