Help Me --Will I blow my system?


Hello, This is a newbie question so I am sorry if it has come many times before. I just bought some amazing Legacy Studio monitors that run at 4 ohm impedence and have a peak rating of 300w. I want to run them with a B&K sonata ex 442, which runs at 200w each channel at 8 ohm. This means though that the speakerrs will be at 400 w at 4 ohm, which is 100w over the tech Legacy rating. Is my B&K to powerful? I have another system the Legacy's can go on, but I was hoping to use it on my B&K system. It should be noted that I have blown a pair of Polk Audios with the B&K, but I heard that Polks just blow with any set up. ( I am very careful though.) I guess this is a 4 ohm v 8 ohm question, one that still escapes me, as I am not so sure what 8/4 rating even means in a real world of listening.

Clean power won't ever hurt a speaker unless you are getting into deafening levels. You are going to be deaf if you try to listen to your speakers at 300 watts continuosly. You may get peaks (canon blasts, explosions...) that will test your system. However, as long as the amp is distortion free, you are safe. It doesn't get much cleaner than B&K.
