Flipping the phase works, but not with bass coming way from behind. Putting it back to 12/24 or 12/12 always work fine and they integrate nicely. Don't know if it's the same on my mid/tweeter (currently at 6H/12L) because I don't know how to distinguish between in phase and out of phase mid/tweet. I may switch to 12/12 in the future.
good point- i have noticed that different slope combinations seem to do more than just change the frequencies a driver is playing / not playing. what does it sound like to you? i don't think it sounds completely out of phase but definitely different and it does affect the centering. i would like to be able to understand this more- to know exactly what i'm getting when a given slope combination is set for a given network.
