I tried an inexpensive ART 311 4 years ago with a Classe 75 SS on the bottom and 45 tube amp on top.
The benefits of biamping in tailoring the attenuation and crossover points (although 1600 Hz was best) as well as splitting amplifier loads was evident but The ART muddied the sound overall and I abandoned the effort.
Some say the Behringer is better but still not too good. The real solution is with the Marchand tube crossovers which will cost you about $1000 bucks. Ron the Speakerman, on the Lansing Heritage site has used Marchands far less expensive fixed, solid state devices recently. Check over there.
