I think they were set +/- 5% too high and the sound/detail wasn't being heard over the volume/difference.
Cross over at 80, both subs volume at 33%, AVR @ 0.
I've tried different cross overs but not since changing the subs volume.
Clearly I don't know as much about the technical side of setting up my system as most here. I know more than most in my circle, that's enough.
I enjoy the tweaking and will live with it as is for a while.
