Mark, keep in mind that the speakers aren't going to be "getting" 200 watts; that may be the maximum power capability of the amplifier, but at a comfortably loud average listening level the speakers will be getting about 1 watt. On brief peaks they'll draw much more than that, of course, but not likely close to 200 watts. There should be no problem with your B&Ws. By the way, it might be a good idea to see if the Onkyo alone does the job with the Axioms, before actually buying the 200 watt units.
