Got a JBL SCS200.5 speaker system for free and was thinking of using it instead of the soundbar. I am going to use it as 3.1 configuration initially (sub, L R and centre). For the sub I found that I should set the crossover at 120Hz but not clear about the other speakers. Have configured them as "small" but their specs according to the manual are 110Hz for L and R and 100Hz for the centre speaker. Should I use these values for the crossover?
