When I set my curves in Jazzis program. And match my speakers to the individual targets in a 3 way system. The drivers all hit the curves nice and all have good phase at the crossover points. Their independent left and right channel total curves match the overall target house curve and each other. But when I take a measurement of the left and right side together the curve is way off. All the drivers don't sum the same amount. The midbass sum much higher than the rest about 5 db. The subs are run mono so they have no summation or db rise especially at the lowest frequencies. How should this be adjusted to reach the final curve? Should I for example raise the bottom end of the sub to get the overall curve to happen again? Should I lower the midbass and try to adjust the curve for the final curve which will make the individual left and right curves different then the final curve of both sides? How about shape and db discrepancies for the mids and highs? Here is a pic of the sub and midbass. That's the curve I am going for, again the left and right side individually hit that. But the drivers in the pic are left and right midbass and the sub together which is creating a different shape.

My DSP is the helix pro v1. Im running digital. So I don't have virtual channels and I also believe the input eq only works on analogue but I need to check. Im using rew and pink noise while doing the moving mic technique to get my readings.

Won't adjusting the EQ even in virtual or the input eq affect the crossover points and phase?

If he gets 5db on mid bass it’s correlated

I’d be aiming for 6db unless it’s mounted in doors, then 5db is good…

I’d want 3-4db through mid and tweeters ideally… all pass can help below 1khz at most, above that I don’t bother, and I’m very careful about them using above 300hz if I’m honest… where a moving mic makes no difference is a good guide to where all pass are handy… not always positive though… so enable and disable

but see what summation you get, post a graph if you get chance of left/right and summed also
I'll post a complete set of graphs here in a bit. What do you suggest though. If you are getting 6db for midbass and various for other drivers, do I work to get the final curve to match my house curve? Because that wont match the individual left and right. If so how do you go about tweaking?
