Right channel has discontinuity of delay at 3.5kHz.Can any one help me analyse what my TA should be base on these measurements?
I have a 3 way active without subs. Crossovers at 250/3500 L-R 24
My mids are the furthest away from me base on measurements. Measurements seem to say that my underseat woofers are further away then my mids or tweeter so they should instead be put as Zero delay and around 3-5ms delay can be added to my mids and tweeters ?
That's good stuff.. I need to crack out TDA and try it again once my system is in again ready for a retune. From memory, it was quite the iterative process when I did it, trial and error. You could really tell when it aligned up the 3D plot suddenly looked lovely, smooth and lined up on the left.Right channel has discontinuity of delay at 3.5kHz.
A 0.7 ms delay (2.5 cycles of 3.5kHz) for tweeter should be good.
Crossover points at 250 Hz are ok.
You should observe 3 curves - TDA, AFR FFTq and GDR with "subtract minimum phase" ON for final decision.
Yeah posts are kinda showing up and kinda disappearing.. The site's got bugs and gremlins right now I think after a software upgrade.Very Strange. I was sure i saw Raimonds and some other replies yesterday. But they seem to have disappeared? Raimonds was saying my Right Tweeter was 0.7ms off? Cant find it anymore.
Anyway I made that adjustment and tried to bring the understead woofer closer to zero. But now it seems like things are a little more messed up. It could be my mic measuring position is a little off. I now have saved the seat position in a memory. The left right should be correct. But the up and down or forward and back may be a little different then the first measurement. This new position however, is the correct position.
I am still a little unsure how to read the charts to make the appropriate adjustments. Seems like my tweeters are a little ahead of my mids which is a little ahead of my woofers.
