That first blue line is a speaker target with the crossover set. He just didn't use the sub tab. The second one is a flat target line with no crossover setting. I think. 
gs... check out this thread post #2 and set your graph axis limits as such so we have some steady comparisons. This will help us better compare to what we are use to looking at. 
Looks pretty flat either way though. I've actually been listening to mine flat of late and seem to like it for some reason. Goes completely against my philosophy though.  What can I say? |
Yes, I'll take another set of graphs for you, one of these days, and show it on a consistent set of axes. Sorry dude, but I've been looking at Bode plots for about 40 years, and I automatically scale them in my head.
Yes, the flat line shows no crossover setting. The crossover is at 80 Hz. The notch at 50 Hz is related, although I'm just a little unsure why its there. As I adjust the phase control in the sub, and the time delay in the AV receiver, I can get the crossover notch at 80 Hz to flatten out, but just as I do that, another one begins to drop down at 50 Hz. It's at minimum the way you are seeing it, and it's only about -1.4 dB. Not bad, but I don't understand why there are two, and that bugs me.
The "after plot" is way flat. I don't think I've ever done a better job, although I've usually been in large rooms that get pretty squirrely at bass frequencies.
Sonnie, maybe your musical taste is maturing. I find that the flat curve sounds the most like live music- I mean live
acoustic music. Even a pipe organ doesn't rattle the windows.
