Home Forums DIY Speakers and Subwoofers Power handling

    n00b question about power handling- if I build a 2 way speaker with drivers where the woofer has a much higher power handling capability than the tweeter, is the tweeter going to burn out?

    @DKL there isn’t really an easy way to answer this. There is what we call a power dissipation, in the sense that the higher frequencies don’t see the same amount of power as the woofer. I talk a little about it in this video:


    The easiest way to guesstimate power handling, is to go off of what the woofer can handle. Model that in winISD and see how much power you can use before mechanical limits. That will give you a decent representation of power handling.

      Thank you. The more I learn, the more I realize how much I have to learn. This is helpful, though.

    @DKL we’re all still learning. And that’s a great thing about this forum. Hopefully we can all learn from each other. Truthfully, we often worry about things that we don’t need to. Unless it’s a subwoofer or a very inefficient speaker, power handling is typically moot. I guess another spot where it might be good to know is with a PA speaker. The point being once they’re in a room, you don’t use as much power as you think you do. I’ve really enjoyed DIY audio guys amp Dynos. He’ll Dino the amp and then he’ll play it on a normal song so you can see how much wattage you’re actually using playing that song. I think it’s quite eye-opening.
