What do you think of this surround sound system?

Help setting up Surround Sound System. Crossover Specifically (I think)?

• I just purchased the definitive procinema 600 speakers with the Onkyo 630W 7.2-Ch. Receiver. We have it set up and love the sound except the low voices sound a bit muffled and are a bit hard to hear. I thought it probably has to do with the crossover and/or low pass filter. I have been trying to find this answer online but each response seems to be tailored to the individual system. The sub has 2 manual controls on it, and then I am supposed to set the LPF of LFE in the speaker settings. Then the crossover for the 5 different speakers. I like the sound the speakers are producing but I feel like I am not optimizing these settings in the speaker settings or on the sub itself to maximize the ability of these speakers! Any help would REALLY be appreciated! Thanks so much!

To determine the phase: speaker polarity can be found by using a battery to determine the positive lead on the speaker (when you touch the positive terminal to the positive lead and the negative terminal of the battery to the negative lead of the speaker the cone of the speaker will move outwards pushing or compressing the air in the room). -Having speakers out of phase causes frequency attenuation (loss), Low (bass) voices shouldn't be heard in the subs as much as the low-midrange speakers. Mis-seting your crossover can damage the speakers (not the amps), causing deformation of the cones (you get a flower petal pattern bent into cones as they try to handle frequencies lower than they were intended to. Though they usually won't fail totally, the cones won't be as stiff as they were, and they'll stop producing even sound levels across the frequencies they were deigned for...
