        You are an utter fricking moron. You don't eq a fricking subwoofer you set your crossover and gain and then move the subwoofer around to the best spot. You're so fricking dumb and probably fall for all the fake fads companies use to get morons like you to buy shit

          Best spot means it sums constructively with the mains. There are other factors you might want to consider like placing it closer to walls to increase room gain, shifting the phase, etc, but it still needs EQ even in the best spot.

        The room is why subwoofers require EQ. Maybe they'd be better off without a room.

    i think subwoofer is all about minimum delay plus power response, one builds some sort of transducer, low end boost and low pass crossover, check phase at crossover frequency, but not eq any further, calibrate by body effects

    Apply a 200hz low-pass filter to the input.
    Play the worst music you can find at max volume.
    Crank the gain on the subwoofer channel until the cone rattles and sounds like shit, then backoff a quarter turn.
    Done.

            Why wouldn't you use an HTPC like a normal person?

            If you want to stick to boomer ways of playback you can buy a minidsp thingy that have PEQ or use a proper AVR that can also have custom PEQs set. REW can generate the correctly formatted EQ files in any case.

        Home theatre is when you buy an AVR with weak ass amps and weak ass DSP because you're locked into proprietary formats.

        And what will you be EQing the home theatre sub with? Your PC's EQ software? And how do you suppose that would work?

        You use Equalizer APO. It just works.

    stand in each of the corners of your room and listen if the bass gets boomy or muddy or if it just sounds bad. that will tell you if you need bass traps and improve the bass in general

      trap filters and physical resonators are unwanted, and not going to improve uncontrolled bass much

          Bass traps don't work for subwoofers at all. Only tuned resonators do.

    You can use any mic for bass. You're only looking for the locations of the peaks. The software is REW. After removing the peaks adjust the overall level by taste.

    There's no such thing, all you can do is adjust the level and frequency.

    If your stereo is high end maybe you can do time alignment. That's all there is to it to subwoofers and everything else is snake oil.

      What is the best way to EQ two subwoofers?

      You treat them like one subwoofer and place them in such a way that the second sub will cover the nulls of the first sub. There is no "stereo" in sub frequencies, although they're so sensitive to the position that the response in one of your ears can be different from the other and you'll hear a shift, even on mono content. You just gotta make the best of what you got. Something like minidsp flex will allow you to do true multi-sub DSP but it's expensive.

    You need good microphone tho even webcam mic worked for me just fine.
    For placement, you should put sub where you head is when listening, play reference tones then find where the bass is strongest in the room and that is place here sub should optimally be positioned.

      Drink audio engineer. I do clubs and venues and festivals and shit.

      A proper measurement mic for doing room correction is always ideal but you can get away without it.

      Find a good position for the sub in your room.
      Download spectroid on your phone, it won't be accurate but it's better than nothing.
      Run some noise and sine sweeps and shit to identify any egregious room resonance peaks and use a PEQ to put a notch there until it sounds better.
      Just don't be dumb and do it too loud and frick something up.
      Put a low pass filter at the frequency your main speakers roll off at.
      Shove a high and a low shelf filter and adjust to taste.

      Your sub is now 'integrated' with your speakers and has been room corrected.

      This guy gets it.
      REW + rePhase + CamillaDSP is the current industry META (I use peace and a minidsp flex at home)

      What is the best way to EQ two subwoofers?

      Umik-1, REW and rePhase, camillaDSP and a raspberry pi. You can probably wrangle Linux on a PC to do do the output channel separation correctly. IDK how tho. Windows is fricked.

      Flex gang rise up.
      A Raspberry pi and camillaDSP will actually perform the IIR and FIR processing better. The flex is a nice unit but a bit limited when you try to push the FIR filtering.
