Something to be aware of regarding the settings versus the room. The settings are made up the same way passive XOers are made. With anechoic measurements to remove the room effects. My room isn't affecting those settings at all.
The cross over needs to eliminate the room because the direct speaker to ear response is very important. This should be flat or slightly down sloping. The room will make it look not quite flat, but that's okay because the anechoic direct sound is. So to everyone, don't dsp your speakers dead flat in room to 20khz. It'll sound bad.
Now, below about 300hz the room is very influential AND our ears care less and less about the direct sound. So go ahead and use the dsp to flatten this out. Caution you don't put big boosts in there, and don't arm wrestle it into a dead flat line. It's not worth it. That's for the sub 100hz region where it's totally about the room.
One last note. Active is better. There's no argument from me there. I conceded that to Penngray without batting an eye when I first joined avs. But don't expect miracles. And don't forget, a bad active design is bad and a good passive design is good. Being active doesn't change that.
Mike, post your measurements if you don't mind and take one at 1m. I had a pm about a polarity problem with the passive version. That would translate into the active version if it wasn't the user's fault which I don't think it was.
