I been using Behringer xxx2496 for 15 plus years now. If you get one all tricked out they are good from the bottom to the top as an active XO. I use it stone stock for bass management. It has everything. RTA (on the fly correction) PEQ, GEQ, digital room correction remote control, and daisy chain via RJ45. I don't use 1/10 the STUFF it has.. The last one I picked up was 275.00. I've never had one fail either.. Get a Behringer mic and they work like peas and carrots..
I've seen them split (the way I use it) 300hz down is the 2496 and 300hz up is a passive system or as an active EQ via tape loop (processor) or between a single component. Works very well in a FULL blown way or on a select piece of equipment (EX: SACD to 2496 to RtR and record)
VBDA, DBA, Swarm, columns and combinations with a Behringer, sure makes it easy... 300 hz and down, BUT you can monitor and see your corrections via REAL TIME.. Move a chair, see a change, move a panel see a change.. Makes it too easy.. I still use preset tone control moving from CDs to Streaming to Vinyl to TV with Stereo. My wife will grab and adjust the tone control.. LOL Windows rattling in the other side of the house..
Like ozzy said it can rob a systems "SOUL", but used the way I use it.. with some room treatment, usually heavy curtains, just magic with MB columns, planar monitors, and option of OB servo subs or VDBA/DSP.
Not like it use to be BOOMIN' friggin' bass
