Agreed witih WaynePflughaupt's advice. People get way to hung up on the power rating and matching thing - especially the inexperienced dabbling in Pro Audio actually. There are two ways to "blow" the speaker. One is by exceeding the driver's excursion capabilities in a violent enough way to cause physical damage, and the other is thermal overload of the voice coil.
In pro settings, I've run double a speaker's rated RMS wattage without consequence because I was careful with my gain structure and didn't send any DC down the line by clipping a preamp or something. (most decent pro speakers have plenty of thermal dissipation abilities above and beyond the wattage where you risk exceeding physical excursion limits, as will most highly efficient home audio speakers) Also, I've runs speakers on not quite enough wattage - in which case you just have to take care with the limits of the amplifier, because if it clips hard enough it will send damaging signals to the loudspeaker.
I've seen people overdrive an amp into clipping and not know what was going on before, but honestly, if you can't hear that level of audible distortion setting in, you don't belong on an audiophile forum. Just make sensible pairings (like maybe don't pair a 2w SET amp with an 82db efficient speaker) and pay attention to the limits of your gear when in use. It's not like you can be running a 100w amp to a speaker with a 200w rms rating at a reasonable level with nothing distorting and then have the speaker magically get destroyed. Of course, speakers at that price range aren't known for their accurate specifications. If they break, don't blame the amp.....
