If you experiment with LFE LPF I suggest matching the speaker X-over. 80/80, 90/90, etc. Don't go below 80Hz for LFE LPF.

With near field behind the MLP Marc wont 120Hz be more localized than 80 Hz?

I believe by reducing the higher bass frequencies which are more directional. I think even at 120/140Hz some dialog can come through the sub.

Probably, but it will differ room to room and ears to ears. Setting the LFE LPF too low can reduce the mid-bass punch. That is why I recommend leaving it at 120Hz to start. I think it is best to get the sub/speaker blend right before messing with LFE LPF. 60/120 is what I am running downstairs (the mains go down to ~20Hz).

BTW, If one thinks they are just going to measure for day and never need the UMIK-1 again. They are easy to flip quickly on the classifieds. You'll get ~75% of your money back. However, once you enter the rabbit hole you likely won't turn back.

So can someone help explain this to me. I'm trying to reduce localization when placing the sub behind me. I might try lowering the crossover to 60hz, but I've also been reading more about reducing the LFE channel to 80hz. Do these differ in the way they reduce localization?

I run one sub in the front right corner and one in the rear left corner. I sit around 11' from the front sub and around 4' from the rear sub. I use 120hz crossover when I listen loud and I have no localization issues. Adding another sub will likely cure any localization issues.

Well I know another sub would help prevent localization. I was speaking more to the idea of the LFE channel reducing localization.

My understanding as far as the frequency's been delivered by the sub(s) is 80Hz LPF setting often is refurred as the (safe zone) where many on AVS have suggested for those who may have been experiencing localisation issues with their specific sub placement. As Marc mentioned you will loose some punch in the upper bass with capable subs so a bit of a trade off. Of coarse multiple subs would be a better option.

I wouldn't go lower than 120hz on the LFE because the LFE takes place 120hz and below. If you set the LFE at 80hz, then you are just limiting LFE content and missing 80-120hz portion. LFE content is the .1 of the system....LFE part only, not the low bass routed from speakers to subs for normal material.

But the sub xover (not LFE part) which you can play between 60 to 120hz but usually 80hz is where its good starting point. But for LFE only, I believe it should be set at 120hz default. Correct me if I'm wrong...but if you set the LFE to 80hz then you are just missing the rest of the .1 content? That has been what manufactures have said in the past.

Also I believe many people get confused between LFE xover and sub/speaker xover sometimes.....I know I did!

Yes, this is my understanding too. The .1 is a different channel with its own content. The speaker crossover routes signal below the crossover to your subs, which is in addition to the signal from the .1.

I messed with my LPF of LFE quite a bit a while back and settled on 90hz, just like my crossovers to speakers. Set your crossovers where you like, leave LPF of LFE at default of 120hz, then play a variety of your favorite movie bass demos. Change LPF of LFE to one notch lower, 110hz, and replay the clips. Repeat lowering the LFE of LFE each time. This will let you know what you like best and is easy to do. There may not be a best for ALL but should be one that you like for probably 95% of the clips. Then just set it to this and leave it. It can make a real nice difference. I'm sure setup, room, equipment, and of course personal preference will play a big roll in what you like best. Experimentation is key IMHO, and can lead to some wonderful discoveries ...don't be afraid

You can do the same for your crossovers as well, just be aware of what it might be doing to your FR at the crossover points, which can be confirmed easy enough in REW or OMNI and adjustments can be made if necessary.

Hi,

I do think it's possible that reducing the LPF of LFE to 80Hz would reduce localization, and I wouldn't be afraid to try it. It was Mark Seaton and Roger Dressler (formerly with Dolby Labs, and one of the creators of Dolby Pro Logic and PLII) who I first heard suggest reducing the LPF to 80Hz. Their analysis indicated that very little content above 80Hz is meaningful. Apparently, a lot of it is just random noise.

And, that is consistent with the original intent of the Low-Frequency Effects channel. It was originally conceived as a way to emphasize low-bass effects more than mid-bass effects. And, it was given an extra 10db to facilitate that. Since that original analysis from Mark and Roger, others such as Marc Fishman, who posts on the forum as FilmMixer, have confirmed the lack of meaningful content above 80Hz in their movies. And, the LPF is just a filter, so it gradually rolls-off content above 80Hz. It doesn't eliminate it.

I have experimented quite a bit with settings ranging from 80Hz up to 120Hz. In my room and with my system, the differences are fairly subtle, but they are distinguishable. 120Hz gives me more bass, but it sounds a little muddier with higher volumes and bass boosts. An 80Hz setting is perceptibly clearer sounding to me. YMMV! But, if I were experiencing localization from a nearfield sub, I would definitely try the lower LPF setting.

Regards,
Mike

I'm unaware of a X-over setting for my subs other than LPF in the LFE unless your refurring to the manual mode in the AVR settings which for my sub's options are 25/40/63/100/160Hz?

Just received my 15v and wanted to double check some settings before I begin my sub crawl and auddessy. Should I turn auddessy off before the crawl as it's calibrated from the old sub. And my back plate settings are
crossover 80
Roomsize large?
Gain 10:00 I understand adjusting this
But what do I do with delay?

Hello @indebtbassfreak , long time no see. AFAIK/IMHO

LFE is essentially 0-120: you do not set this frequency, and you don't want to as it is creator's intent, part of the "rule" of the Dolby and DTS codec, etc. It includes low, mid, and part of upper bass. You run the subwoofer full range (turn its crossover off) and let the processor sends the (already limited) 0-120 signal to it.

Crossover Setting is a different issue altogether. There are two crossover settings: one on your subwoofer, and multiple on your receiver (which for example has 11 of them for each of the 7+4=11 speakers in a 7.1.4 system). The crossover setting is used for example when a typically small surround speaker can't cover the bass range, since it has tiny bass drivers. The receiver's crossover setting sends 20-80 Hz to subwoof and 80-20k to the small speaker. In my system, I again turn off the crossover on the subwoofer, and let the receiver sets/determines the limited 20-80 signal to go to subwoofer.

LFE you leave at 120 (don't touch). Crossover you could use 60, 80, 120, etc. depending on the surround speaker's low bass capability. 80 Hz and below is desirable since above 80 some people start to be able to localize the sound. ie Left surround bass now appears to come from the subwoofer behind you. For this reason, it's a good idea to get a "competent" surround speaker. For example you would like the mid/bass driver of the surround speaker to be 5-6 inches, as opposed to 4 inches. Just trying to help and hope I haven't repeated material you know well.

What size was your room again? You would want to find the ideal position for the sub before EQ so yes Audyssey off.

Hey cannga good to hear from you. My AVR does not have a second X-over setting for my sub. In the Configuration menu where i can set each individual speakers X-over,,,,, when i get to the sub the (only) option is the low pass on the LFE. The only other adjustment in my AVR that i have ever seen is in the equalizer setting menu. I have audyssey setting,,, and manual,,, thats it. In the manual setting i can manipulate the five option frequency's 25/40/63/100/160Hz. Other than that i see no other adjustment in my older AVR. If there is one then i've been in a long coma.

As for my subs,,, they have a DSP that is way beyond my pay grade and maybe this adjustment can be done there but most subs have the same low pass on the back with the option that most use by turning it all the way to (LFE) setting letting the AVR to do the work.

Is it possible my AVR just doesn't have the extra X-over setting been discussed?

In the case of jgourlie who's only option at this time is one sub behind his MLP away from his front sound stage ,,,,reducing the upper bass either by LPF at 80Hz or this other X-over sub setting seems to be a good start. At the end of the day (sub placement is #1 )

-Chane A-1.4 side/rear surrounds.

Yes turn Audy off,
Crossover, turn all the way to 150Hz highest setting.
Gain 10-11:00
Room Size large is fine.
Delay leave at lowest setting 0ms

Will you be using a SPL meter?

I coulda sworn we had this LPF LFE talk about 2 to 3 weeks ago. It was very helpful. Like most are saying, experimenting is free!

Yes I just got a umik 1 and plan on REW calibration this weekend. I used your settings and believe I found the 2nd best spot I can use, the first failed the girlfriend test but they were very close.

@Mark Seaton and @Roger Dressler are both amazing and humble. But I don't think Roger wants credit as the creator of DPL and DPLII (Jim Fosgate). Roger should eventually jump in and clarify his involvement in the creation of Dolby codecs (like DD+ and True HD).

You need to verify both the second and first best locations with REW, hopefully they will be close enough that either spot will work well in your space and you can keep the GF happy, if not, threaten to buy another sub and I bet the first best spot will pass the GF test............. enjoy...........

Good lord, I just read the last few pages of the JTR thread...what a train wreck! Now I know why I see some members posting here that use to frequent that thread. At least there is a good group of guys here in this thread.

LFE is essentially 0-120: you do not set this frequency, and you don't want to as it is creator's intent, part of the "rule" of the Dolby and DTS codec, etc. It includes low, mid, and part of upper bass. You run the subwoofer full range (turn its crossover off) and let the processor sends the (already limited) 0-120 signal to it.

Crossover Setting is a different issue altogether. There are two crossover settings: one on your subwoofer, and multiple on your receiver (which for example has 11 of them for each of the 7+4=11 speakers in a 7.1.4 system). The crossover setting is used for example when a typically small surround speaker can't cover the bass range, since it has tiny bass drivers. The receiver's crossover setting sends 20-80 Hz to subwoof and 80-20k to the small speaker. In my system, I again turn off the crossover on the subwoofer, and let the receiver sets/determines the limited 20-80 signal to go to subwoofer.

LFE you leave at 120 (don't touch). Crossover you could use 60, 80, 120, etc. depending on the surround speaker's low bass capability. 80 Hz and below is desirable since above 80 some people start to be able to localize the sound. ie Left surround bass now appears to come from the subwoofer behind you. For this reason, it's a good idea to get a "competent" surround speaker. For example you would like the mid/bass driver of the surround speaker to be 5-6 inches, as opposed to 4 inches. Just trying to help and hope I haven't repeated material you know well.
This is exactly what I'm saying. I think people are confusing LFE .1 content with the speaker/sub xover rolloff. Or maybe they are not confused and set it lower such as 80hz for LFE, but if you do that then what will play 80-120hz? Definitely not the other speakers since its .1 LFE only which goes to subs and nothing else. So that is content they are missing IMO.

My prepro doesn't have LFE setting and its set 120hz from factory which is a good thing....but I do have sub/speaker xover settings separately.

Sorry guys. That was part my doing. I just could not understand the whole numbers between the subs being compared. That has been an issue as you all know for some time.

I do think it's possible that reducing the LPF of LFE to 80Hz would reduce localization, and I wouldn't be afraid to try it. It was Mark Seaton and Roger Dressler (formerly with Dolby Labs, and one of the creators of Dolby Pro Logic and PLII) who I first heard suggest reducing the LPF to 80Hz. Their analysis indicated that very little content above 80Hz is meaningful. Apparently, a lot of it is just random noise.

And, that is consistent with the original intent of the Low-Frequency Effects channel. It was originally conceived as a way to emphasize low-bass effects more than mid-bass effects. And, it was given an extra 10db to facilitate that. Since that original analysis from Mark and Roger, others such as Marc Fishman, who posts on the forum as FilmMixer, have confirmed the lack of meaningful content above 80Hz in their movies. And, the LPF is just a filter, so it gradually rolls-off content above 80Hz. It doesn't eliminate it.

I have experimented quite a bit with settings ranging from 80Hz up to 120Hz. In my room and with my system, the differences are fairly subtle, but they are distinguishable. 120Hz gives me more bass, but it sounds a little muddier with higher volumes and bass boosts. An 80Hz setting is perceptibly clearer sounding to me. YMMV! But, if I were experiencing localization from a nearfield sub, I would definitely try the lower LPF setting.

Regards,
Mike
Quick clarification on my own recommendation on this. It is less about if content above 80Hz is meaningful, rather that most of us will have the subwoofer overall set higher than the main speakers. When we set the sub higher its effect with the main speakers is limited to taper off with the low pass setting of your main speakers. As such frequencies at and above the crossover frequency taper into the response of the main speakers as frequency rises. Since the LFE channel and bass from the mains are all part of the "sub" output, such a setting boosts the entire LFE channel frequency range up to the LFE low pass frequency; 120Hz typically by default. The more you boost the level of the subwoofer channel rather than just tilting up the lowest frequencies, the more you raise the content above ~80Hz. Since a large majority of you cross your speakers at 80Hz or lower, this can make the LFE channel a bit strong in the top end of it's range. The low pass is a slope, not a cliff, and lowering the frequency simply tilts down the highest frequencies more vs the 120Hz setting.

Think of this as the opposite of tilting up the low frequencies of your subwoofer by using PSA's room size control or my LF Adjust. This tilts down the upper range if you have it set a bit hot. Since this is only on the LFE channel, you won't hear it on music, and possibly less so on some scenes you demo. In short, the more you raise the subwoofer level from a calibrated flat energy, the more I would suggest lowering the LFE low pass might sound preferable. Despite how many portray such adjustments as wrong or deviation from accurate, we're simply saying this is an entirely justifiable and warranted adjustment you can use to get the best result in your room, just as we often tell you not to be afraid to raise the subwoofer to get the balance you prefer.

Thanks for the clarification. Would you believe that lowering the LFE to 80hz would help with localization problems as well when running a sub near field?
