. . . not sure you really want this to be your primary criteria for speaker purchase. I would not. Rather, pick the speakers that sound like and look like what you really want, and cost w/i your budget. In all likelihood they will have dual binding posts (most do) and be "biampable" (most are). You can verify this as your last "tie breaking" decision.
I suggest you also read up on biamping. Search the archives here and you will find extensive discussion. It sounds like you are considering "passive biamping" which rarely produces a benefit as you will read in the archives. "Active biamping" is a whole 'nother undertaking and since it removes the crossover, you may not need to worry about whether the speakers have dual binding posts.
