Onkyo 605 Speaker Configuration

Eduard

Hi guys hope you could help me, I just got my Onkyo 605 receiver and Polk RM6750 5.1 speaker.

This is my current settings:

Subwoofer: YES
Front: 120Hz
Center: 120Hz
Surround: 120Hz
Surr Back: None
Surr Back Ch: ---
LPF of LFE: 120Hz
Double Bass: Off

Is this correct or I need to change it?

Thanks in advance!
