Most People's Subwoofer Crossover Settings Are Wrong 

You should always use LFE...if you don't see it on the subwoofer (my older 15 inch doesn't have it on the back), just turn the frequency to the highest point you can. The receiver still controls what frequencies get sent to the sub. I had mine set to 80hz like a fool for a long time..when I fixed it, I immediately noticed a massive increase in sound quality. I was repeatedly told to never set the frequency to 160hz even though that's exactly what was needed. Setting the crossover frequency to a set point means anything higher won't go to the sub. The decision making should be at the receiver. You'd be surprised how certain frequencies in movies are higher but still designed to be sent to the sub.

You just made me think about my car audio, I'm guilty of setting them both haha. fix in the morning, Thank you! well explained and great vid!

A lot of people don’t understand how to set crossovers as they don’t understand the 3db down point right before compression, there speakers might be 3db down at 60hz at 1w but when they throw some juice at them and get closer to reference level the 3db down might now be 90hz, there is a lot more to what it might seem.

Big up bruh..took your advice and let me tell you my subs are producing even louder and stronger bass. I turned the xover on my amp at it's highest point. On my electronic xover i I set the frequency lower, and it was louder and stronger Unbelievable !

Very well explained brother! I set the crossovers in the reciever and leave the sub in LFE mode to bypass any filtering there.. It depends on speaker size and room of course, but ive found 80 hz to work great...voices are filtered out and yet the bass is still hard hitting and solid... if you have ever dropped the point too low ,say 50 or 40hz, sure you wont have any deep voices bleeding thru the sub but you will also be missing some of that upper bass that lends impact... 80hz is a great compromise that allows impact and yet keeps voices out of the sub as well as making it hard to localise where the bass. is coming from ....there is a reason that 80hz is used and chosen for THX sound standards

For those using SVS subs with their app, to set LFE mode touch the settings icon on the upper right, then choose Low Pass Filter, then choose off on the toggle. This puts the sub in LFE mode and defers crossover settings to your AVR/processor. Make sure to do this for both subs if you're running duals.

I've had my theater (7.3.4) for about 5 years now and never new this. I turned the subs to the highest setting like you said and rite away I heard and felt the difference. It's amazing how there is always something more to learn. Thank you very much for this wonderful video.

Nice tip. I built my own subs recently and tried this out. I was missing stuff for sure. Now I'm testing lots of my movies all over again.

Also, if one would like more output from their sub, use both rca inputs via a quality y splitter. There is at least a 3-6 decibel sound difference.

Ive been on this for 30 years, and this is a pretty good walk through for beginners in home cinema👍 But can i add some to your video on this? «Dont always trust the calibration tool on the reciever 100% if you are using that. When its done, go over all and check them, sometimes they are way off. Both hz and distance. Example after calibration: Left front: 3.25meter (10.66feet) Right front: 1.65meter (5.41feet) Left very close, right is way off. And also check size of speaker settings. Sometimes you want the front to be playing full band, if the front can handle it and your reciever can. But as you said, if you want to not overload the reciever, choose crossover on them. Good video🍿🍿

hi, i have a pb-1000 pro, is in lfe mode on the sub, and adjust the crossover on my receiver. yamaha tsr-700

In 3 way and above speakers in the crossover there is also a bandpass filter/crossover for the middle speaker.

I'm team stereo receiver, so I rely on my subwoofer's cross-over. I prefer my cut-off point at 70hz.

BTW I like your explanation of the dB roll off. I am very much still learning about this stuff which is why I was so disappointed with what I think I heard about LFE in your video. Hopefully I was wrong. If not then hopefully you will correct it. :)

Not always the best case. I have two subs and tower speakers. Using stereoamps highpass filter to cut them at 60hz and adjusted subs to play from 70hz with a 24db slope. Got the best result and integration like that. If ur not so familier of tuning your setup then its a good idea to use lfe from av receiver and sub. But if you dont get the best result like that and you know how to work with the equipment you have. You can do either way🤓

Great video my subs knob i turn all the way to the right pass 150hz to the word bypass its always been set there my avm90 i set my main to 80hz and heights and rear 90hz sounds great except for an acasional popping from my subs. Working on getting that fix i hope😮

Dude this is just what i needed! i do feel i will need to replay parts many more times.and i am just trying 2 channel plus a sub.Thanks for this man!

I have my SVS Subwoofer set to LFE and in the AV Receiver l have all my speakers set to 80hz and the Subwoofer is set to 90hz which l have found sounds better than 120hz it blends more with my speakers and gives good impact, bass effects for movies and TV shows

good afternoon bro, quick question; I always hear you talking in some of your videos about mini DSP. Which one do you have connected and how are you hooking it up. Thanks

It's probably best to set the dial on a subwoofer to "bypass" for the crossover. Enabling extra, uneeded filters or crossovers can potentially add slight delay, which can possibly mess with the integration between the mains and subs.

So what if you are using the svs app

LFE+ Main for music, because LFE can limit on music only track not sent through Dolby

Wouldn't the use of one sub on a 2 channel music setup overwhelm it with too much bass coming from both channels as opposed to using two, one for each channel?

For music listening,, I am an old fashion minded guy, no sub and that's my preference. For H/T application then yes sub crossover from the AVR/ Pre-Pro crossover is set to LFE @ 80 Hertz as recommended by THX.

My Yamaha 1080 doesn't let me set the crossover for the sub. It has parametric eq tho.. but it seems i have to use something to read the waves in order to make adjustments( already did ypao but it didn't sound as good as my manual settings. I manually set the fronts to 60hz, surround to 80hz, center to 90hz.. i tried using parametric eq just for the sub but I'm not sure what to set the 4 lines to. Db, Q, etc

Very helpful. Lfe set.

People also forget, subs are its own channel! It’s not just used to play bass that your mains can’t play. For music, sure.. but movies?! Nooo.

I have the Klipsch RP-1000 with the crossover dialed on LFE. My Marantz SR6015 crossover settings shows LPF for LFE: 120hz I was told to leave it at 120hz. Is this my current SW crossover setting on the AVR? If so, what should I change it to for the RP-1000SW? My remaining speakers are: Klipsch CDT 3650 C II x4 Klipsch RP-504 C II Klipsch R-5502 W II x2 Klipsch R-5650 S II x2

They have Polk and Sony up firing speakers on sale at Best buy I would have to put them on top of my height speakers that are on the top of my tower speakers what's your feelings on that will I be able to hear the sound clearly

I use fmods 70hz hipass to douk line amp to monoblocks then blend but not amp the line to sub parametric eq on plate amp Then the sat/sub 70hz can warm or cool the bass pressuration of the room.

I have turned my AVR and subs to the highest settings because of the use of a mini dsp to calibrate the subs it’s the only way to get it right. I use passive subs and I setup the amps on full range to get a accurate response for the bass to play at a smoother frequency.

@Kpaceguy, I have the monoprice sub 9723. I get what you said at 5:00 and 8:24, set max on sub and set 80 on AVR. Question : what about volume on sub? do you recommend 10 oclock, 12 o clock, 1-2 o clock? Any suggestions. Also, what effect this volume knob on sub has on overall sound. I always had my volume and crossover around 1-2 o clock position without doing any setting on Sony DH 540 AVR crossover. on different note, I did make speakers small and then crossover setting gets enabled in Sony DH 540 AVR. However when i set it to 80 on avr, I didnt notice any difference. I didnt leave it on for a long though as I quickly went to L speaker and other settings. I have a Sony DN 1080 and just got Pioneer LX 305 sitting in a box that I need to setup with atmos speakers. That would be my next project. I dont get much time so havent connected those yet.

Question does the LFE input on the sub also bypasses the function of the phase control ?

My amplifier doesn’t have a filter setting but it has base and treble nubs.

But what if you have more then one sub

@Kpaceguy - Hello. I took time to watch this great video again as you recommended: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-asJW0Aa7p8E.htmlsi=nnSckjL-kwl2uDwF With over 500 comments, there was one part in this video at the time of 7:20s where you mentioned if any words are muffled, it may be crossovers are not set correctly or that the subwoofer is set to high. Thanks to you I fixed my crossovers but I experienced the muffled voice in a movie dialogue and had to lower only my center crossover to hear it clearer. Maybe I missed hearing you talking about the sub volume is set to high and how to fix this. Currently on my Marantz SR-6015, the physical gain knob on both subs are set at 3.5db. In the Marantz settings are: Audio | Subwoofer Level Adjust SW1: +0.5 SW2: +1.0 Audio | Speaker Levels SW1: +3.5 SW2: +4.0 I feel like my sub volumes are too high which caused my mumble, but I myself and probably others don’t know how to make the sub volume correct plus do not fully understand these settings. Please advise

Beautiful explanation!

After watching this video I realized that I forgot to turn my sub's crossover to max after adjusting the LFE setting on my HT receiver awhile back. I then turned the bass on my receiver back to 12 O'clock as I no longer needed to compensate. Thanks for the reminder bro.

Is it a jet plane folks on the porch, folks in the recording studio that the setup allows you to hear new experiences, nope the new amps, the drivers are better and the 18's are just now broke in. I'm gonna live one more summer LETS JAM DIYERS

Kpaceguy, you are awesome!!!! You explained exactly what I've been looking for all week. thanks man keep making great informative videos.

So, I turned my Crossover on my Sub to it's highest level, then I went into my crossover setting on my Onyko receiver to 80HZ.... Is that what you are talking about? If they is right, then what should I set my main speakers at? They are bookshelf speakers (Acoustic Audio AA351B indoor mountable black full range speakers, 20-500W per pair, 100Hz-20 kHz, 89dB, 8ohm). What should I set them at on my receiver?

Brother, this is a fantastic video. I've learned so much and I keep referring back to this video and tweaking my system. 🤝🏾

BROTHER PLEASE HELP ME I Bought a Bastian 100 watt 6 speaker sound bar from temu ! I KNOW lol I just hooked it up to my computer and I get so much feed back when i plug it in the wall i even tried diff outlets what should i do can i fix it or just pour gas on it lol it really is a tv sound bar but it has AUX plug PLEASE HELP bevfore I hang myself with the wire !!!!!!!! joke THANKK YOU

One more question: I know this thread is about subwoofer crossover setting, forgive me for changing the subject a little and may I suggest another new video on our main listening speakers. My remaining speakers frequency responses are: 1. Klipsch CDT 3650 C* II- 63Hz-23KHz ± 3dB 2. Klipsch RP-504 C** II - 50-25kHz +/- 3dB 3. Klipsch R-5502 W II - 46Hz-20KHz ± 3dB 4. Klipsch R-5650 S II - 60Hz-23KHz ± 3dB *= Ceiling **= Center W= In-Wall Mains S= Surround Currently they are all set to 80hz crossover. What would you recommend the crossovers to be set at? Audessy initially had them set at: 1. Top Front Ceiling 110 hz Top Rear Ceiling 80hz 2. 40 hz 3. 100 hz 4. 100

Most peoples subwoofer settings are wrong. Including yours if you set your receiver LFE to anything other than 120Hz. That's the maximum frequency for the LFE channel in an audio mix. So if you set it to 80Hz you are potentially loosing 40Hz worth of LFE information from the mix. In fact you will see it argued in almost every article you read that this shouldn't even be a user adjustable setting. Good advice on the back of the sub setting. Very bad advice on the rest. Use LFE/or highest crossover setting on the back of your sub and set receiver LFE to 120. The leave it alone and never touch either setting again.

Great info on todays podcast 😊

Interesting, thank you for this, please may you explain what this means - my speakers spec says Frequency response 49Hz - 26kHz, and it also says crossover frequency 2kHz - what do these two specs mean?

My Polk psw505 doesn't have a LFE crossover it only goes up to 120hz and my two polk HTS12s only go all the way to 160hz

Do you set the hpf the same way

That was interesting what you said about if you want to use your subwoofer crossover. Buy putting the amplifier crossover to the highest I didn't know this. So which one of these two would be the better using amplifier crossover or subwoofer crossover

Avr cross over

The 2.1 system is much easier to setup

What about those of us who don't use a receiver? For example I have a B&K PT103 pre amp with a sub out. Not adjustable in the pre amp. I typically run 2 rca's to the sub since I find with most subs it sounds better, or at least more powerful sounding. Should I turn on the LFE in my sub or leave it off. The LFE connection on the sub is only 1 rca. I have a SVS PB2000 PRO so it has the app I can use to adjust it. Thank you for the great videos!
