Speaker/Sub settings help

All,

I'm the proud owner of the following sets of speakers and have some questions.

Center - 15c
Rears - 35B
Fronts - 45B
Sub - PSW505
Receiver - Denon AVR591

I used the Audyssey feature and here are the current settings

Fronts - 40 - small
Center - 60 - small
Rears - 80 - small
Sub - LPF to LPE 120HZ


I have been playing around with different settings, but I'm curious what others commonly choose for this type of setup. 80 on everything, including the sub? I've tried 80 and it sounds good, but I'm trying to optimize for the best sound. We probably listen to music about half the time and use it for movies the other half. If I change the crossovers, do I need to rerun Audyssey?

Any help is appreciated.

Regards,

Will

    You won't need to rerun Audyssey after changing the crossovers. I would leave the LPF to LPE at 120HZ regardless of other settings. What is optimal will depend your speakers in your room. I would set at 80 Hz for all the speakers and try some adjustment from there. (I would not usually go below 60 Hz unless your speakers are truly full range.)

    So to clarify what is the relationship on the LPF to LPE setting and my other speakers? If I have all my speakers set to 80 and the sub LPF to LPE set to 120 does that mean I'm missing the frequency from 80-120?

    It is the low pass for the low frequency effects channel which is a separate channel of low frequency information available on multichannel recordings (technically it is the .1 in 5.1, but the decimal is now often used just to refer to the subwoofer(s)). The LFE probably almost never includes any information above 120 Hz, but the general idea of the LPF to LFE is to protect your subwoofer from receiving higher frequency sounds that it can not play effectively since the LFE input on subs is unfiltered.

    For you receiver, the cut-off frequencies you set for your fronts, center, and rears all function as both a high and low pass filter for that channel in the recording. The high pass for what is sent to that speaker and low pass filter for what is sent to the subwoofer.
