What was wrong with the XM46?

I would think it would be the "best". Could the real problem be that 2nd order at 70 hertz isn't truly the right thing?

There are things you can do with a digital filter but no way would I consider the Behringer a "step up".

If I was you I'd buy a few extra cards for the XM44 and play. Best to get some measuring gear too. Don't be afraid to try weird stuff, like 4th order 65 hertz on the mains and 1st order 50 hertz on the subs (just a silly example but you get the pic).

Also play with placement of the subs. I'd start with one under each main speaker and then try one between the mains and one halfway back in the room on the side wall firing towards the opposite side wall.

Considering all the problems with getting good bass in a room I'd be inclined to blame something other than the crossover as well as be prepared to try a fair amount of "trail and error".
