I just read your post in March Phileosophos and my heart sinks knowing that 7 months later and there's no word that anything will be done about it. On a side note, that ty_ger07 person was so off point it was incredibly frustrating to read!
I was completely accurate from a technical standpoint. Center channel is monotone and that is where bass exists. It's fundamental.
Now, if EVGA's implementation is messed up and doesn't work as it should, that is not tested by me and is totally out of my control.
Don't call me off point when I am completely technically correct about the way it is supposed to work.
When I made those replies, I was under the assumption that there wasn't anything technically wrong with EVGA's implementation. Since then, I have become convinced that there is either a software or hardware issue. When I read how people had to tweak things in a completely ludicrous way just to get 3.1 to work, I knew that there is a problem.
I haven't posted much here since, because it is pointless for me to give advice based on a technically flawed product which doesn't behave as it should in the first place.
Instead or asking for crossover control, perhaps you should ask for proper center channel implementation in the first place. If the center channel worked properly, I am certain that you wouldn't need crossover control. Crossover control is a bandaid for a bigger root problem.
I now agree with you that it is messed up. But I still disagree about why it is messed up and how it should best be corrected.
