No, you will be fine. In fact, the more power you have available, the safer it is for your speaker. What blows speakers isn't having too much power... It's having too little power, and the weaker amp is producing distortion trying to pump out high volume with too little power. The result is called "clipping", where the high-frequency noise created by a weak amp shreds the speakers. Having a high-powered amp doesn't mean that that power is constantly being delivered to your speakers. It means that that is the power that is AVAILABLE when needed, and that is usually in very short bursts. Most of the time, your amp is loafing, at 1 to 10% of its power. It's sort of like how you CAN lift 150 pounds, but that doesn't mean that you are always walking around carrying that much weight... But the ability to lift 150 pounds is there when you need it. So your speakers are in good hands with your powerful amp.
Sorry, there was a problem. Please try again later.That Yamaha amp is NOT 150W RMS per channel. It is more like 125W Nominal(Not RMS). What this means is, you can hook it up to your AVR and crank to the max and this speaker would play loud and clear and would be no where near damaging it.
Sorry, there was a problem. Please try again later.No...and I actually answered the last q wrong asking about a 110w rms amp. I thought it was 150rms rated but it's 100. With that said, you have no issues whatsoever with this. The only thing it means is, don't run the speakers at max volume as that is beyond what they are rated. But the odds of you cranking it up to max are right around zero. You're good to go no worries, don't even think about it.
Sorry, there was a problem. Please try again later.I have driven the speaker at high power levels with my Sony STR-DG810 receiver with no issues. I doubt you will have a problem.
Sorry, there was a problem. Please try again later.I can not answer but, if it were me I would stay within correct RMS specs so not to worry or void warranty..
