biamping Usher BE-20's


I was thinking of biamping my Usher BE-20's. My Audio Research 210's would drive the mids/tweets and maybe one of the class D amps for the bass. I'm thinking Wired4sound, Bel Canto 1000's or??? The 210's are rated at 27db gain so I figure if I can get a bass amp/s with the same gain it should work good? I can always get the Endler attenuators if needed for the bass amps. Any suggestions/opinions about how this might work and sound? I'm a little concerned about the 540hz bass/mid xover point on the 20's - 540 seems kinda high to me.
thanks!

Funny you posted this topic...was thinking about similar solution (JRDG) for my Dali Helicon 300.

Another audiophile emailed me regarding BC REF 1000 paired with the Helicon 300.
Researched Wyred 4 sound 1000 with Emerald Physics compression drivers.

Good amp.
Lapierre, JRDG 201 are based on 500ASP modules and not on 1000ASP modules. . . they have half the power of the 501s. . . I would not use them to drive bass region of large speakers. Guido
