    Another method, if you have access to two smart devices (phone, tablet) is to install a tone generator or subwoofer tone app on the second device and a sound level meter (NIOSH or similar) on your phone. Test the speakers alone to see how low they go first. When you find the frequency where they drop off about 6dB, set the sub crossover at that frequency or a little lower. Then do a frequency sweep to set level of the sub.
    I would stick with the crossover point, but adjust sub volume level as Paul says - turn it up til you hear it and then back down slowly until you don’t. Perfecto!

    The best sounding crossover frequency of the sub and level settings - including phase - largely depends on your listening room. But more importantly, you should not hear your subs when listening to chamber music - or the acoustic guitar and hand-held harp intros of your favorite death metal tracks before the electric bass guitar and the kick drums kick in.

    Great question . I tell folks to tune the subwoofer until it disappears and the mains sound Bigger . It's the most simple way I found to explain it. As far as frequency I have then start at 120hz and work down . Most people do not understand bass and working down at least un my exp. tends to be better absorbed by the average non audiiphile.

    I actually do the exact opposite, at least at first... I start at a higher frequency and dial it down lower. I can hear the redundant sound, and when I hear a certain track where that happens, I turn the x-over down. I do go back and forth - going up and down when I get tracks where the main speakers are close to the bottom. I usually do this with the gain on the sub turned up. After I get the x-over dialed in, that's when I focus on the gain level. Just an alternative that's worked for me many times. Maybe that might work better for someone with ears like mine for what it's worth.

    Hi, we have a 2 channel 31 band EQ with a crossover on the back so it sends left mix, right mix and sub outputs to the active speakers. Our speaker set up is thr typical small band sub with a pole with the mid high speakers on top. We send the left and right to the top speakers and the sub to one of the subs and then send a link cable to send an identical signal from one sub to the other. Pretty straight forward. My question is, the crossover frequency can be set on the back of the 32 band eq, therefore what should we set the sub cut off frequency to? It has options of between 80hz and 200hz. Thanks.

    Hi I have Definitive Technology BP-8020ST. These speakers are speakers that have built in plug in 8 inch sub woofers. Their frequency is about 20 to 30 thousand. Normally, I have used the speakers plugging in the power for the subs in the wall, without plugging the sub woofer cable from the speaker to the amplifier receiver. Doing it that way the base was pretty good. So, I thought I would ALSO plug each of the 2 subwoofer speakers special sub plug into the receivers sub 1 and 2. I am not sure how much of a difference that will make seeing that they are already subwoofer powered? Am I supposed to unplug the subwoofer part from the walls if I am hooking up the subwoofer to the subwoofer one and two of the receiver? Right now I have the subwoofer speaker plugged into the wall and the subwoofer cable is plugged into the receiver as well. Secondly, what would I set the crossover frequency with these type of speakers. Thanks.

    Sounds like he's assuming the setup he advocates with no crossover on the mains. Then you have to set the sub to the mains. However I noticed a Yamaha A/V receiver spec'd the high pass as 12 dB and low pass as 24 dB/octave -- this means it is also meant to make partial use of the main speakers' rolloff rather than having to be set well away. Some other units don't give any specs.

  • @charlesludwig9173
    @charlesludwig9173 Před 3 lety

    The folks at JBL recommended my low pass be set to 63 Hz. My mains are flat to 35 +\- 3db so I set high pass to 50 Hz snd this works well. Yet there’s one more thing to all of this snd that’s what gain is set in the sub. Mine is set to deliver the same SPL as mains.

    Most subs have 2 knobs.. volume and crossover. What should the volume be set at when we are testing for the correct crossover? And then do we change the volume once the crossover is set correctly? Or does the volume knob affect the crossover tab??? These are questions no one ever answers because when I'm testing the crossover, the volume affects at which point I hear the sub as its own entity. So idk which should be set first or how the volume should be set in order to actually set the crossover. That's been the question I've been stuck on.

      you should read the comments hre, lots of great advice here.
      if you still want to know some specifics then adjust volume of subwoofer first, the crossover, and crossover point stays fixed with volume, but increasing volume causes the frequencies above crossover point to be elevated so it can sound like its crossed over higher that it is. you also did not mention phase adjustment, so its 3 knobs on most subwoofers.

I just wished more people put that into their subwoofer tuning video because no one seems to tackle that issue of what the volume knob should be set at when tuning the crossover and then what to do with the volume after the crossover has been set

    Another path is to do a proper cross-over in an external DSP and let the subwoofer rule the sub bass without your side speakers messing it up trying to do mediocre sub bass in parallel. Especially small bookshelf side speakers will sound better if they don’t have to be stressed reaching max excursion due to sub bass coming to them. A DSP can also allow critical bass tweaking, EQ and phase control against room acoustics enabling a much more optimum response. One example is this: czcams.com/video/zr_oqF9jb-8/video.html

    now just sit in your listing position and drag the frequency slider around and now you can hear all that the speaker sounds like in the room to your ears. you quickly hear when the main speakers starts to roll off, read the frequency and set the subwoofer to that number on the back of the sub plate amp. some more frequency sweeps and you can confirms if it is right. then volume to match speakers and do some quick phase testing on subwoofer to do the last little bit :)
    when its all done its about as even response as you can get for now, if you get some loud parts in subwoofer range lover the volume a bit. its better to have dips than peaks.

      Exactly. I previously had my 280s crossed at 80hz (with a sealed SVS) because everyone said "help your receiver, let the sun do the work" but the lower kick bass you want to hear punch with music is missing that way. It doesn't sound the same if you let the sub do all the work. So if I run them large tho in multichannel stereo (my preferred music setting), I noticed the sub basically doesn't play at all anymore to augment the very bottom frequencies if set to LFE. Even if I set the crossover to 40hz for the 280s but 80hz for the rest. You'd have to run it LFE+main and that doesn't quite sound right. I'm going to try crossing at 60hz across next. I don't listen that loud anyway so the amps should be fine.

    I understand that the 45 Hertz is restricted due to the cabinet size of the main speaker on the audio Pro.
    Is this frequency range restricted by the amplifier also?
    Is the sub out on the audio Pro restricted to this 45 Hertz or does it allow for a much deeper frequency range.

      If I on CZcams find a frequency tester With which the frequencies range from 20 Hz let's say up to 45 Hertz, does this mean the sub out will go to 20 Hz if I can hear it through the sub?
      I have tried this and I can hear below 45 Hertz on the sub with the audio Pro connected to CZcams on a frequency checker.
      Do you feel this would be an anomaly or am I actually listening to the amplifier producing lower frequency sound than comes out of the main speaker because of its limitations?.
      I know you may be thinking silly man. If you can hear it it must be there.

      Low frequency bass is non-directional so you might be able to get by with what you have.
      As you can see from Paul’s mindset he certainly feels main speakers need to be able to deliver decent bass themselves. I agree. I have tower type speakers.
      I once had bookshelves with a sub and I always felt mid bass was lacking. There was a gap.

I have never came across this problem as to i have never had a amp that has 24db slope.
    I have drawn out my crossover graphs to see maximum output at what frequencies. Ive found 100 hrtz is best most low out put but still just sound horrible unless the song has certain notes. How do i get my sound back.. lol i need huge help as im stumped i mean.. i do know my lpf cant be turned off from my deck so right there thats boosting attenuated signal but like dayum i dont see a way to make it better.. maybe thinking too hard.. but ya bassicaly lpf is 6th order .. ive seen thats "speaker attenuation" (cone doesnt move rlly which yes verry true from sight. My deck has dm+, eq, and ability to swithch possition.
    As well this is my first time tuning with multimeter ive tested tunning at 40 hrtz with gain then changing hrtz on the filters and it was bad so i changed to 100 hrtz gain set after that it was still bad but lows were there nothing crazy tho, went to 80 gain set not my liking, i am thinking trying 120 but like i do know my box i made is a ported box tuned to 28 hrtz, that will effect my output too wouldnt it?..
    In all end tho its really comes down to fact that i cant turn off my lpf from my deck or is there another way to get back my sound without dsps or anything? I also if i +1or 2 or anything on the sub thats going to boost the lows yet bring up the highs. Which im "set" were my highs from my subs are already to my liking just the lows arent there

    Most average size rooms if they're not size of a cathedral will not hear 30 Hz you'll be lucky to hear 50Hz it's impossible for the wavelengths interact in such a small area you're here it outside alright but not in the room. Some enforcement if the speakers against the wall will go down lower.
    put your subwoofer in the corner facing the corner 45 degrees slope upwards and have it at -15 DB at 20 Hz then you might achieve 0 DB at 20 Hz if your room is big enough
    Subharmonic synthesizer will help what will lower it by one or two or three octaves from 100hz

    • @C--A
      @C--A Před 3 lety

      While the wavelengths are very long the ears and brain work together to enable you to hear the bass. Play bass frequency test tones of - 100hz, 70hz, 50hz, 30hz, 15hz and you will be able to tell which is the lower frequency. Even in a small room.
      This is a similar effect to 10bit tv's that have colour volume greater than the human eye. But the brain and eyes work together enabling you to notice the greater colour volume on a 10bit tv compared to a 8bit tv.
      My subwoofer has a subharmonic synthesizer (but with protection built-in so you can't break the sub) fun fact back in the day the popular major discos started installing subharmonic synthesizers to get better low frequency bass on the dance floors.

    Room, speakers, placement has affect here.
    My main speakers go down to 32Hz (I think it was) but in my room the sub plays best with them when I adjust the LPF to around 60-65Hz.

    The question that I have ... What the volume of the SUB should be? I can have my sub at 50hz , and it will barely present at , say 20% volume, but say I turn it up to 50% and it will show up, but then at that volume turning crossover to 90hz will bring it upfront even more... So this is my dilemma. Is there a recommended volume starting point, when I need to start bumping the freq up.

    • @lobstame
      @lobstame Před rokem

      Volume of the sub should be at or around eleven o’clock position or just slightly less than half volume. Later on after you listen for a while (days or weeks sometimes) you adjust up or down in volume to match your average listening. It took me months friggin with this until I liked what I heard. Or you can buy one of Paul’s test disks and manual. Ultimately it’s what you think sounds good according to your setup. This kind of fine tuning on all your gear takes a lot of time. Use a CD, not your turntable unless you know what you you want well in advance. Hope that helps.

    • @JoeJ-8282
      @JoeJ-8282 Před 3 lety +1

      That "rule of thumb" holds true for a crossover frequency within a main speaker from the woofer to the tweeter for example, but not so much for a separate stand alone SUBwoofer. If you brought a subwoofer's crossover frequency up to that point, many times it would be too high of a frequency, and therefore it would sound a little bit too loud or even "boomy" because it would be augmenting too much of the main speaker's bass frequency range.

    • @gyrgrls
      @gyrgrls Před 3 lety

      @@JoeJ-8282 Of course, I was kidding. WHIH, tho... the lowest my active sub will roll off is 40 Hz... and the main speakers cut off at 30 Hz. The sub low cutoff is 16 Hz, so 32 Hz would give me that first octave. Not ideal, but close enough for horseshoes and hand grenades. But I was only kidding about driving the woofers no near cone breakup. That be well into lower midrange, and we want as flat of an overall response as possible no matter what the crossover type or woofer arrangement.

  • @NathanOakley1980
    @NathanOakley1980 Před 3 lety

    Measure your in room frequency response for left and right speakers combined.
    Crossover the subwoofer where the speakers are about 6db down, usually around 60hz on floor standers and higher for smaller speakers.
    Measure combined response of speakers and subwoofer, if there is a peak at 60hz, lower the crossover to 55hz. If there is a dip, increase the crossover to 65hz.
    Regardless of how it is accomplished, you are trying to achieve a flat response from 20hz up. In an untreated room this is unlikely but try to get the best balance possible, the sub should only reproduce frequencies that the main speakers can not. The only way to actually achieve this is to measure and find where the speakers you have actually roll off in the room. The manufacturing specs are pretty useless for this as the room response will always differ from the measurements.

    • @NathanOakley1980
      @NathanOakley1980 Před 3 lety +2

      Acoustically treat your room before you get a sub! If the manufacturer claims your left and right are flat to 40hz (at 1W 1M in an anechoic chamber) then the speakers will be a lot closer to that claim if in *your* room if your room is well treated. This often costs about the same as a decent subwoofer.....
      .....then add a subwoofer, hi-fi heaven can be yours! Low room distortion is the way forward if you are buying this level of gear.... or even if you aren’t. The room adds more distortion to the listening experience than any other component.

Now let’s complicate it with tower speakers with powered subs using LFE, an SVS PB1000 Pro, dual Def Tech Pro Cinema Sub 60 tapped into the tower speaker terminals, and a Polk PSW-505 tapped into the Def Tech high pass outputs.
