Just slightly above my level of understanding for tuning so it was a very educational video for me. Kind of a leg up in understanding. Thank You. I will save this video for reference in my future efforts.
I´ve been messing around with the sound system alignment in my church for a while. So I have been watching all your content, I´ve read McCarthy´s book, your book, and other good stuff on the internet. But nothing beats real world examples. Thanks for sharing this info.
What does the C mean in subaligner when you look at the result plot? …also Aligning Speakers that are phase compatible from the same manufacturer… could you recommend a video to watch on that
C = center. It's the geometric average between the start and end of the crossover region. > could you recommend a video to watch on that I would consult the manufacturer on that.
I'm tying to wrap my head around the notion of measuring each speaker independently, equidistant from each one, when these locations aren't where the listeners will be, and not where we're interested in the interactions between the two. Is this like, a theoretical starting point for alignment as if the two speakers are at the same point in space, and do you then attempt to follow it up with mic placements at listening locations?
You got it. Ideally, we would have put both speakers on the ground next to each other or on tall stands, but they were already in place. It wasn't an install, just an upgrade to the DSP. This done in order to get high SNR actionable data, since measuring out into the room can often make the trace go FUBAR. > do you then attempt to follow it up with mic placements at listening locations? Yes, please see this article: www.sounddesignlive.com/can-you-remove-reflections-from-live-measurements-for-more-accurate-alignments/
Hi Nathan, Again Good Stuff!!! Thanks a lot. What is this Tool? This doesent look like Smaart right? The Second Question ist very basic level question. because i do not have an educational background in Sound Engineering. (Just my hobby this is :-) ) How Come that you said the summation on the Cross over Point should be in 6 db bei same phase? I have hear adding 2 Waves with same amplitude cause 3 dB summation in apmlitude. Which one is correct? Thanks in Advance
Hi Priyan, good to hear from you. That's Crosslite. It's another audio analyzer from Brazil. Great for playing with filters. > summation on the Cross over Point should be in 6 db bei same phase? I can tell you that uncorrelated summation is +3dB and correlated is +6dB, but it will make the most sense if you measure it yourself. You don't even need an audio analyzer. You could just insert some correlated signal on two tracks in time and watch it sum and then the same for some uncorrelated. You might use two copies of a sine tone since it's easy to measure and then two different pink noise files.
Interesting video as always! I know it was a quick job and as always ‘pick your battles’ but next time you’re trying unmatched filter types & slopes, move the mic out into the room and verify the results as you get farther away… even if you’re not looking at phase out there due to reflections, you should be able to spot fluctuations in the magnitude. I’m also curious on your logic for the mic positions? 1.2m from the grille on each box as the crow flies makes sense, but if the mic location isn’t coincident for both traces, I’d personally want to verify it again after fiddling at a coincident location on the audience plane. After all, that’s where people listen and our ears aren’t microphones 👂 🎙… although on that note did you see the webinar with 606, Jamie Anderson and Merlijn? I’m tempted to mock up a dummy head of sorts for binaural alignment verification but it’s gonna be a long ways off give the number of projects I always have! You seem to be a big fan of Crosslite+ lately… please stop making me crave yet another analysis tool! I already have SMAART, SysTune, EASERA, RoomCapture, RiTA and REW 😅
Hi Kyle! > move the mic out into the room and verify the result I did! :) I just didn't talk about it in the video. Please see this article: www.sounddesignlive.com/can-you-remove-reflections-from-live-measurements-for-more-accurate-alignments/ > I’m also curious on your logic for the mic positions? None. Just speed. With more time I suppose I would start at 3x the baffle diagonal and move closer until there was actionable data, but in this case we just put a mic up there, measured the distance and matched the distance with the sub. > did you see the webinar with 606, Jamie Anderson and Merlijn?

Thanks Harerton! What's going on with the system at your church?
Good work🙏🏻 thank you Nathan
My pleasure!
This is really good. Thank you.
Glad you like it!
Master class! Thanks a lot for share this!
Glad it was helpful!
Nice one, Nathan.
Amazing video as always. What is the software that you’re using for simulation?
Thanks Alexandr! Looks like Crosslite
Nice one Nathan !

I know, right?! Too many tools.
There is no “best way”
Did you use pink noise to get your readings? Or what did you use?
Hey Benny, I'm not sure what stimulus was used during measurement, but it was probably pink noise.
