Found your post just by accident.
What specific points do the single curves in the magnitude plot show?
1m is probably already too far away. When moving away from the source, the room "takes over" pretty soon.
In my measurements dipoles performed far better than monopoles.
I believe XT doesn't provide the necessary resolution for good low frequency equalization. XT32 performs much better.
They are from the middle line(from front to back) across my couch. i accidently deleted the right seat, but it looked pretty much the same as the top line. Those were what I figured--need the "32" version and also may need to lift them off the floor. The 32 version is out of the question. I'm probably going to just fix the non working sub and return to the five sub configuration. Well, I may actually get some even beefier subs. My old low end had a lot more impact. These infinity subs just don't reach down as deep, and the EQ won't force them to do so.
Thanks Markus! Your experiment worked out extremely well. Best bass measurements I've ever seen.
Can you link to the thread of the original discussion please?
