LFE vs Main Sweeps

[408Revo]

Hi Everyone. Looking for some help on trying to understand why when I have a flat response curve on my LFE channel, it changes when a run a sweep on my LR channels.

Example: I'll run a sweep on my LFE channel and response is relatively flat from about 110 to 20 hz. I then run a sweep on my mains, and the frequency response around 55-60hz start to slope up towards the 20s. From 55hz to 20hz there is around a 8db increase. I'm wondering why it doesn't maintain a flat response if that's how I setup the LFE channel to do using filters. Any feedback is greatly appreciated. thanks

You should probably post an mdat file with measurements that illustrate what you are trying to describe.

see below snippet. The top blue response is a from my LFE channel. The lower orange response is from LR channels. I incorrectly stated above the frequency response for LR sweep. Looks like from 100hz it dips down to about 65hz, and then ramps up to 20hz. I have my XO set to 110hz on my mains. Wondering if I just need to do a better job on matching my mains to my LFE channel?

When I set my curve on my subs I should be using my LFE channel, correct? Not my LR channels?
