A little late here, but I concur that there is no comparison between these Polks and the Sonys. Maybe the Polk M10 or T15, but not the Monitors or TSis.

Nothing happened to them--as far as I know, speaker companies have always outperformed major consumer electronics companies when it comes to speakers. If the reverse was ever true, then it was before my time. Sony's decent equipment is overpriced and not well known to the public, while their entry-level audio products have never been very good. They still make some of the better boomboxes, but in comparison to regular speakers, that's not saying much. Among consumer electronics companies, Yamaha has probably had the most success with speaker quality.

They've gotten better recently (especially their large speakers), but they're still way out of their league against speaker companies. That goes for Onkyo, too.

No because at any given time the receiver is only giving the speaker enough power to play at whatever volume is set. For casual background listening, that's barely 1 watt most of the time, although obviously it can get much higher at loud volumes (like when watching a movie). In this case, the receiver will obviously be the limiting factor, but as long as you stay within its limits with the volume control, then it won't be underpowering the speakers.

Yes, if you turn the volume too high and a really loud sound is played on a soundtrack, then the receiver may basically short-circuit and literally fry the speaker's drivers (specifically their voice coils). This doesn't happen too often, but it can happen. Usually you'll hear so much distortion (or the soundtrack will just be so loud) that you'll naturally turn the volume down before any real damage is done, or the receiver will sense an overload and shut down by itself, but since you asked, yes it can happen.
By the way, having a receiver with a lower watt rating than that of the speakers may not be ideal for the safety of the speakers, but it is the common case for the general public and even many audiophiles. Just don't go crazy with the volume, turn it down if you hear distortion, and like most people you'll probably be fine.
