Time alignment tutorial

[altoncustomtech 773]

I thought I’d share this here. The writer goes through great length to explain the why’s and how’s of time alignment in a stereo system. He explains comb filtering, phase issues and alignment, crossover settings and so forth. Plus he does it in a manner that pretty much anyone with just a little bit of background or experience on the subject can understand.

Please forgive me if I’m wrong to link out to another manufacturer’s website forum. If so I will go through the trouble of copy/pasting the content.

Thank you sir.  I’ve read through it a few times and I think it’s great info for getting started tuning an active system with a DSP. As is stated in the tutorial there’s more to do after finishing these steps but this seems to lay a very solid foundation to work from.

That's Andy Wehmeyer in those tutorials

Thanks for the post.

I'll take my time to read all.

Awesomely cool technical read Alton. Always neat to see measurements along with an explanation, such as the graghs showing the reflections along side the signal. Also the graphs showing where an x-over point ends up once one source is boosted from another. Makes sense of why what would seem like a separated x-over point and slope can blend better than what one would think. lol

This was the other point made I found interesting. I don't believe he mentioned tweeter polarity anywhere though, except in regards to phase shift with crossover slopes.

I am in the process of installing a new DSP (h800), So was a perfect time to read this. I will give his approach a try!

Definitely!!  That’s why I posted them all up, it is great information for the inexperienced and the experienced alike.

I can’t wait to hear how that goes!
