How to verify main+sub alignment in Smaart® [GSwSST34]
1. Match main and sub to target level
2. Identify crossover region
3. Are phase traces within 60º?

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 site.

Thanks Nathan..
I don't have Smaart, or any other measuring equipment. I literally have to guess what's going on and try my best at my venue. We currently do a lot of local bands, but we are moving up to booking bigger acts, and I told my boss that we are gonna have to get more serious about phase alignment and equipment, because bigger artists are much more meticulous about their sound and setups than we have normally dealt with at this point.
Amazing! You are the best, Nathan!
Great knowledge but that loud clicking of the mouse is truly nerve-racking!
Very thankful for this resource Nathan. One question. How do you set the reference delay when measuring the sub vs tops? Or do you simply take all the measurements without delay locating?
Hi Nathan - I really appreciate all of your hard work! Really informative and easy to understand, however, I do have a quick question regarding this topic. I've seen this process done in various videos, however, it always appears that sub crossover alignment is verified against only one main. I happen to use a center sub configuration. Would you still just align with just one of the mains?
Hey Nathan, could that phase issue actually be from the reflection from the floor? I wonder if those speakers were on the edge of a stage if that would still happen. Thanks for the smaart tutorial.
Just stumbled upon your channel. Love it! Was wondering what processor you are using to add delay, etc..
Hi Nathan. I see a lot of people in Smaart videos delaying the mains to align phase. While this makes sense with a ground stacked system, when it comes to a system with flown tops does it not make more sense to delay the subs given that they are physically closer to the point of reference, in the same way you would delay a delay speaker to the mains and not the other way around? Is it possible to determine which matrix to delay to achieve the best results by looking at the phase traces?
Hi ! How do you know if you're not aligning with a whole wavelengh delay (or 2 and so on...) ? Thanks.
Hello. Thank you for your videos. I have a question. Some subwoofers can reproduce frequencies up to several hundred hertz. How to find the upper boundary of the crossover region in this case?
Hi Nathan, I thought you already had 2.6ms delay on output 1 from the previous video. But then you started this video with zero delay on output 1. Can you explain? Thanks
Hi Nathan, Can I do it with Smaart V8 demo? Can I verify phase with demo version? I really hope you can answer me, thanks
Hey Nathan, great explanation! I have a question: when I check the two phase for the delta at the delta frequency, the first is at 150° and the second at -45°. Do i have to calculate 150-45 or 150-(-45)=150+45 ?
I am slightly confused about the centre of the crossover region, If the subs where I work are set to crossover at 80hz, how do I find a centre? Is this something done visually on smaart? Using Smaart di right now. great video btw.
Does it make sense to use a burst or kick drum sample instead of pink noise that way the subs and mains are In time and not just phased??
What order do u use on your crossovers point
Hi nathan , what about the delta phase if fro example my cross over point is 94 Hz and my sub phase is 100degrades and my tops phase is -89 degrades how i can calculate?
Why you use crossover to check phase? I'm a beginner of SMAART.
Do you know: Can I do the delay measure in REW? (So : frequency response close together, then identify the crossing frequency, then see the delay degree value, and if not within 60 degree ?
