As a relatively AV ignorant person can anyone comment as to whether there is a concern regarding the power of the amp being too much for the speakers and blowing them. There is no problem with the 6.2 fronts as they are rated to 200 watts.
Three brief points, sharkane: First, Swan rates conservatively, both for acoustical specs and power specs. Second, in general speaker power specs are approximate, meaning that while there are formal tests for various power states into a loudspeaker, the ratings are based on destructive testing, meaning that the final number advertised for the speaker is somewhat speculative.
Third, and much more importantly, unless you were to run a steady-state signal at full power into the speaker, or unless you clip an amplifier frequently and heavily into the speaker, you'll not test its limits often. Audio program power is tied to loudness - to your hand on the volume control - and to the typically dynamic nature of its content. You just don't routinely explore the amplifier's limits, if ever, and therefore its spec doesn't correlate to the speaker's well.
Hook em up and enjoy em. Especially for a big speaker with lots of voice coils, the speaker's rating can be more or less ignored. More speakers die from a lack of clean power than from genuine overpowering with undistorted audio power.
