Honestly I don't like Xovers any lower than 60 hz. thats what the sub is for.

Until OP clarifies settings this "argument" is going nowhere.

Not really actually. I know they are under two different menus on your AVR, but what do you think the xover is for your mains? Well I'll tell you, it is a HIGH PASS FILTER. what does this mean? it means the AVR will send the full bandwidth signal to your mains ABOVE where the xover (or high pass filter) is set. so just for an example, you set your mains at a 40hz xover. Below this point, the avr will begin to attenuate the speakers response, probably at around a 12db/octave slope. Why? to protect your speakers from playing frequencies they arent meant to play. Next question, what does this crossover do to your sub? absolutely NOTHING, this setting is purely for where you want your main speakers response to start sloping off to your sub's response.

So where is your sub's response set to play to now? 120hz, that means from 40hz to 120hz, your mains AND your sub is playing the same content. What does this do? usually creates a peak in the midbass response, sometimes muddies the clarity of quick bass hits or kickdrum beats, and overall is something you DONT want to do (unless you decide you prefer the hightened midbass response, to each his own)

So why do you set the LPF for the sub at the same spot as the xover of the mains? to prevent them from playing the same material, and almost always yield a smoother response overall.





that is not true, unless you are talking about bypassing it outside the AVR or at an external xover or something of that nature otherwise you couldnt be more wrong. Yes, the avr does need to control the sub's xover, but choosing the 40 or 60 or 80hz xover for your mains, does absolutely nothing to the sub. that is why they let you select the LPF of the LFE seperate, so you may adjust accordingly. My mains play to 80hz while my surrounds can only get down to about 80 or 100, so should i choose an 80 or 100hz LPF for the SUB? its up to me, but that is why AVR's give you the choice. when I have a full 7 channels that can play down to 40hz, then maybe ill only let the sub handle 40hz and down! thats the whole point of tweaking and seeing what sounds best

I think jackbuzz meant the external Xover which is on the amp of some subs.

Raising the crossover setting for the individual speaker channels is your decision. Probably not a bad idea, here, though. But these settings are completely independent of the 'LPF of LFE' setting. Changing them only affects what happens to the information encoded in that particular speaker channel.

And the crossover that is applied to the speaker channels only applies to the information encoded in those particular channels. The LFE channel information is treated and routed to the subwoofer completely separately from the way that the speaker channels' information is treated. Completely separately.

This is all very basic info as to how bass management works in modern AVRs. It's simple, too. Please do some reading up.

Bass redirection
When Dolby Digital and DTS reached the home, there was one important difference. Cinema speakers are MUCH bigger. A normal sound mix will generally contain deep bass in all the front channels, as well as low-frequency effects in the LFE channel. Home speakers usually don't handle deep bass that well, so it is usually advantageous to redirect bass from the main speakers to the subwoofer. Home DD and DTS receivers offer a bass management function to do this.

With bass management enabled, there is now an important distinction between "LFE" and "Subwoofer" channels. LFE specifically refers to the LFE channel of the original soundtrack. But the subwoofer channel contains both the LFE channel and redirected bass from the other channels.

While the LFE track has its very own encoding, there is going to be some similar low frequency information that was always encoded to the main speakers. maybe you should do the reading up, an excerpt from the sticky at the top of the subforum:

The 'LPF of LFE' setting is a low-pass filter that is applied to the LFE channel information and the LFE channel information ONLY. It is completely independent of and has nothing to do with the crossover that is being applied to any of the speaker channels by the AVR.

And, no, the AVR's crossover does NOT simply function as a high-pass filter. The AVR's digital crossover provides both a high and low-pass filter component. So, for example, with a channel's crossover set to 60Hz and the LPF of LFE set to 120Hz, the subwoofer IS sent any signal below 60Hz from that particular channel as well as all the LFE channel info below 120Hz.

The LFE channel can contain information as high as 120Hz and in almost all cases where a sub is being conventionally utilized the 'LPF of LFE', in so-equipped AVRs, should be set to 120Hz (or higher, if possible). Setting it lower truncates the LFE channel information that is being sent to the sub and that information is discarded completely.

And, yes, when using an AVR, the subwoofer's own internal low-pass filter (often mistakenly called its crossover) should be bypassed completely if the sub is equipped with that capability and if that is not possible it should be adjusted to the highest setting possible. This is because you want the AVR's digital crossover to provide the low-pass function, not the subwoofer's own internal low-pass filter.

Right, the audio mixer will have probably overlapped some of that info into the other channels. But if you apply a crossover setting that is appropriate for that channel's speaker, that info will be sent to the subwoofer and not to the speaker.

The 'LPF of LFE' setting has absolutely no effect upon music listening. None. Unless you are listening to music that has a specifically encoded LFE (.1) channel. In which case you would most likely still want the full LFE channel info to be sent to your subwoofer.

an AVR's digital crossover capability is truly that. It IS a crossover. If you set a channel's crossover to 60Hz, any info encoded in that channel above 60Hz will be sent to the speaker and any info below 60 Hz that is encoded in that channel will be routed to the subwoofer. And, yes, of course the filters are not brick walls. The high and low-pass filter components will always have an associated slope, so, yes, of course they overlap around the actual crossover region

Backpedal all you'd like. You posted some misinformation in this thread. The idea that the 'LPF of LFE' setting must be set according to the crossover setting that is being applied to any of the individual channels is very wrong. The 'LPF of LFE' setting is only applied to the LFE channel and what it does is completely independent of the crossover setting that is applied to any of the speaker channels

In my case, which is what I was trying to convey to the OP was that during some playback, I noticed that content that was not only on the LFE channel but also above my xover point on the mains and playing through them at the same time, gave me a huge midbass boost that made the sound of my front stage be WAY off. when dropping the LFE cutoff to inline with my mains (which are quite capable down to 60hz I assure you), the issue was better. True I may be missing out on some of the purely LFE content, but for any other mixed content, it proved to give me a much smoother transition and response. while the crossover settings are completely independent, the sound sometimes that results is a culmination of all the speakers in play.

MY rears are also at 40Hz and center is at 60Hz. My issue seems to be that I like my music with the fronts set as full band. The sound to me is much warmer and fuller with my setup. I listen to music about all the time with the DLPII music setting on my onkyo. With regard to the speaker settings is there any setting anyone could recommend something so I am not constantly toggling back and forth or endlessly messing with the settings ( or is this part of the audio video enthusiast disease) My music is streaming on MOG.

I suspect that you have some room peaks, the effects of which you are diminishing by tossing that LFE info. You're not really addressing the problem
