I wouldnt bother to bi amp surrounds unless they were full range and for a music surround, for movies I dont think the cost vs benefit is really justifiable. If you are gonna cross over speakers at a limited frequency then why bother as the amp isnt going to see a tough load period.
Thats just my opinion, I bi amp my mains and bridge my center but all 4 surrounds just get regular power.
