For wattage it is worded that way because if you are going to listen at loud volume levels it is better to have an amp/receiver that is more powerful than what the speakers say they handle. The reason is if the amp/receiver is pushed too hard to achieve the volume level you desire it will start to clip ( distort the sound and the signal) which is actually more damaging to speakers than slightly over powering them for short periods of time. Plus most receivers may say they are rated at 130 watts/channel, but if you look closely at the specs that's with only 2 channels being driven. Most good receivers only put out 70-90 watts per channel with all channels driven.
Yes they are pretty good speakers, but what does that mean? Speakers are so subjective its really all about what you think sounds good and how it sounds in your room.
