I recently completed my tri-amp system using a Behringer xover. It is quiet and clean, so I'd recommend. The only troublesome part is making all the XLR/RCA connectors. All the pro stuff uses balanced in/out, but the behringer can be used unbalanced by shorting the - to gnd on both in & outs. The unit uses 24 db Linkwitz-riley filters. Check it out. They are quite reasonable at 129 for a stereo 3 way unit.
