This is my attempt at recreating the results described in an AES paper called Subwoofer positioning, orientation and calibration for large-scale sound reinforcement. Comment with your ideas for improvement.

I love to geek out about the physics of sound. This channel focuses on the growing opportunity for live sound engineers to improve their confidence and consistency through the understanding of the principles of sound system design and optimization. My goal is to make this channel upfront and honest about my success and failure, so you can learn from both.

I am always open to suggestions and feedback so please comment on this video or contact me through my

    I have 4 52's (old i know) but it's what the band using our venue is allowing us to use. Also 4 18' powered subs. I aux them all. 52's on aux 7, 18's aux 8. I started having them LR of stage.... and just recently moved the 18's across the stage underneath. They're about 4-5ft apart....I was able to reduce volumes of all subs .. and even put 2 extra mains the owner had.... inbetween the middle empty sections of the subs pointing as if they were monitors. On their sides facing upwards. A cloth facade is all that blocks the front of them all.. and it sounds INCREDIBLE. I have almost no equing on the subs, just a 20hz hpf and slight db reduction on 60, 80, 100. It totally transformed the experience positively. It took me a year of messing and learning, but I'm finally pleased with the sound on and off stage. I tested the mics in front too, just because I was concerned ab feedback at full volume and with the right eq/gate/comp there was absolutely no tweaking required. If anyone is wondering my eq mix for mics, I usualy go 4:2 ratio on the compressor with 22-24atk/5hold/20release. Cut up to 140hz with hpf and very slight tweaks with skinny peq adjustments depending on what's happening.

    If it was me, I'd be moving off the stage by that meter as you said and probably do a delayed array with the center being 0 added delay. Really helps even out the low-end response in the room especially in that 270-degree issue but that would probably require more subs to be ultimately effective. Just my initial thoughts though lol I'm very much still learning.
  • Hi nathan, have you tryied a center cluster of subs forming a triangle where the two front sub stacks are facing at a 90°, the rear cluster is inverted for cancelation towards the stage... this has really worked for me!! You should try it on the program see what results im getting!! Thanks
  • Hi Nathan , the cancelation in the back can be improved adding an end fired / gradiend array Sub in the front line, it will generate more destructive waves in te back of the entire array . :)
  • @CarlsOpinion
    I always like the answer to the question: "Just BUY more subs". Gee, why didn't I think about that?!? I'll just run to the store, as soon as I pull that silver spoon out of my butt!
  • @haxtofi071
    hey nathan, is there any chance you can do a video of how to calculate spacing between horizontal subwoofer array and how to find delay per sub?
  • I really am novice to subwoofer cancellation and array time align, i only own the dbx driveracks, maybe i need to use more in my m32 x32. i dunno how to use smmart even. can you do a very basic video from the beginning of setup to show how to set up a crossover and such. Thanks
  • Great job Nathan. Only thing I would suggest is NEVER let 100 hz get near your subs.
  • @vivekpatel264
    I haven't watched all the vdos regarding this article but why we are using gradient pattern? Or is it just for trying out some options?
  • Hi Nathan. Is there a reason why delay wasn't applied to the subs in an increasing increment as you move outwards from the centre ? What about the subs being 1/4 wavelength apart as a distance compared to the 4m distance initially indicated ?
  • @weldninja6922
    Hey i have a question, so when setting up subs in say a cardioid type of set up. Would i need to have several speaker management systems, like a dbx drive rack i dont understand how i can set delays on some and not the others when running multiple subs. Thanks for any help. As you can probably tell i am a rookie.
  • @eiltonxavier
    how would be the distance with 7 columns and the processing? thanks !
  • What’s the spacing between each set of subs and how much delay is each from the center subs at zero thanks
  • @kuriakos36
    Hey buddy can you help me please im making a new home theater and my space is 5m * 3.30m * 2.09m high and i have 2 monoliths 15 can you please tell me how i can find the best position to my subs?? How i can make it to 3d in pc or maybe you can make it and tell me where i have to put them exactly 🙄 Please Little help🙏🙏🙏
  • @dantonliam
    Would you not cross the subwoofer quite sharply at 80-90 HZ?? Wouldn't that eliminate your 100 hz issue? No one wants to listen to 100hz anyways
