THS

Hello, I have the following setup. I have listed advertised frequency response. Klipsch RF-62 II Fronts: FREQUENCY RESPONSE: 35Hz-24KHz ± 3dB Klipsch RF-52 II Center: FREQUENCY RESPONSE: 67Hz-24KHz ± 3dB Klipsch RS-42 II Surrounds: FREQUENCY RESPONSE: 62Hz-24KHz ± 3dB Klipsch SW-110 Subwoofer Onkyo TX-NR515 What should I set the low frequency crossovers to ? I was thinking maybe 50hz for fronts, 70hz for center and surrounds ? Thanks ! EDIT: Not sure if it matters but all the walls are soundproof (double layer with green glue) and I build 8 acoustic panels using Safe'n'Sound mineral wool insulation.
