My sound card is currently being used as an analog pre/pro for my 4.1 home theater. (Hercules GTXP 6.1) The crossover is unadjustable and fixed at 540hz! graph I think this is the reason why I always hear voices come from the subwoofer during DVDs. Does anyone have any ideas how I can fix this... I'm using dual parts express plate amp/tempests as subs... I suppose one fix would be to us 4 speaker mode and use the high level in/outs of each sub to each main and disconnect the LFE connection. If I do this then what should I set the plate amp crossover to and will I still get all the "deep" bass? Other than that, the only setting I have to play with is speakers set to "small" or "large". Hercules is supposed to have a driver update that allows the user to adjust the crossover setting.. has anyone found this?
