Power Dissipation

Hello, I'm kind of new to designing and building speakers, and I am currently working on my first project. I am making two two-way bookshelf speakers on a limited budget. I am using the Dayton Audio DC130B-8 (woofer) and the Dayton Audio DC28F-8 for my tweeter.

I am currently using Xsim to design the crossover and I ran into a question/problem. When I look at the power dissipation graph (amp is at 40watt) the curves for the tweeter and the woofer are both over their rated RMS. And when I set the amp at 100 Watt, both driver exceed their max Watt rating.

I was wondering if that was an issue and that I was running the risk of blowing out my speakers, or if I was missing something, or how I could fix this issue (without exploding my budget).

Thank you so much for your responses in advance🙂

You won't be putting 40W continuous into those speakers unless you are the sort that listens to pure sine waves at high volume for fun. Actually some bass-heavy music is a bit like that, but you really need bigger speakers to do justice in that case. 40W for bookshelf speakers is probably fine - more likely to hear clipping distortion well before voice coils baje.
 
VituixCAD 2 has also pink spectrum with adjustable corner f, crest factor and optional HP+LP. But it's too professional and not made in the USA or British Empire so just ignore it.
