I have a velodyne subwoofer with its own crossover conrol. It has a set of L/R pre in/outs to connect to the processor (no conection to the "subwoofer out" jack). If connected to a 950 is the crossover of the velodyne set at the same crossover as the 950? (my front L/R speakers are B&W Matrix 805's, so the L/R fronts woudl be set to small--or do I set to large because the L/R front pre-outs connect to the amp via the velodyne?). Also, the front L/R pre outs would connect to the velodyne with 12foot cables, then back to the amp with 12 foot cables--would this cause any big problems?
