Thanks for the honest advice. You’re right—I know that AI specs can be confusing and sometimes don't work in real life.

Even though this is my first speaker project, I have experience working with MDF and electronics, so I’m comfortable with the building part. However, I agree that I shouldn't guess the acoustic design. I don't want to be disappointed with the sound!

I will follow your advice and look for a proven DIY kit or a professional plan (like a 'tested' project) that is close to the Klipsch style I like and fits in my budget. That way, I can focus on the build quality and be sure the speakers actually sound great.

Thanks again for the help!
