I was running DR300s loaded with magnum 12 (now 4012HO), crossed at about 1.5kHz to a pair of eminence PSD2002, bi amped.
I the HF section was inverted with relation to the mid, and delayed by about 3ms. A parametric EQ was used to give a relatively broad boost centred around 8kHz, and (from memory), another boost was applied at about 250Hz (on the Behringer ultracurve).
A relatively flat response(perfectly adequate) could be achieved with just the parametrics on the ultradrive.
I Didn't properly tweak the settings, but this should get you started. The EQ used besides the ultradrive parametric was like so:
Overall, sounded good for dance music. I believe the sub/top crossover was around 80Hz.
