The Linkwitz-Riley Disaster
Posted: Fri Oct 26, 2018 2:09 am
So for a long time I have fooled with different butterworth/linkwitz riley crossovers and have not had much luck. I understand how to wire one up, I understand how to run the allpass filters to phase compensate, I understand to compensate for the 6.02/db dip at the XO for every 12db/slope.
I built my own out of butterworths, great phase response - no latency (other than phase) no noticeable distortion - but couldn't get the response correct due to the 6.02 dip and my lack of getting the peak band / Q width perfect for the compensation at the XO.
I've read up a bunch, and found the Dozius one on the filter, as far as I can tell, it works great EXCEPT the cutoff frequency is not full range, and only goes from 1k ^ (what gives?), and only 2nd & 4th order are available (I want steep controls !)
If someone could please come to the rescue, I'd love to finish the rest of my device but the end of the week, and there's a lot more to do. I wanted to do it alone but this Linkwitz-Riley XO has been a headache for too long.
I just need the perfect LWR crossover.
