nicknick: Thanks. the speakers say 15w to 200w I would of thought you could give them 200w and not blow anything?


is the rated power RMS , or Peak ? how long can they take that rated full power. What frequencies are Ok at that rated power ?
specs are often BS


that MAX power is a VERY approx sort of thing . Tweeters will blow (easily) , woofers will hit xmax (easily) and literally hit the end of max travel.
That would be a electrical max power , for average music . Speakers will hit max excursion , you'll have really high distortion, it wont be ~200w~ of volume


That sort of power you'd want PA type speakers  , designed to run at high power (rather than designed for high qual audio) . 
I can put tyres rated for 200mph on my small car & install a turbo'ed v8. I wouldnt want to drive it at 200mph .

Guitarists get by with 50W guitar amps, thats enough to play small venues . Thats enough to literally make your ears hurt in a house.
so 200W ........



Buy a multimeter and connect it across your speakers (set to measure voltage) .
You'll be really surprised how loud 1W is, and that 10W is b8gger all louder than 1W

You;re forgetting efficiancy, some older home speakers with a decent bass response are way down on others with less response, and between an 87db @ 1w @ 1w and something more current and efficant with a port but terrible bass response will be a huge difference in power needed to get a nice listening level.
