I moved the sketches for the loft so they won’t intersect the main box. And it works that ways. It’s strange, and I’m not sure it’s the real reason it failed before.

Thanks, I verified the sketches twice, there’s no open wire. Fun fact, if I delete all the other objects, Freecad can happily make the loft…

thanks, I’ll try that. so far I only used the Part Design and Sketecher workbenches, I’ll try the Draft.

3D printing, I plan on placing the left angled side (of the top left sketch) on the printing bed, this way I should avoid supports.

I will try a AC filter if I can find one at a decent price.

at the price of losing my warranty unfortunately.

I had a similar room configuration, I placed the surround speakers on the floor against the wall on each side of the sofa, pointing upward. They did the job to surprise me when watching horror movies when there’s something making sound behind you.

After further reading about filters I ended as the same conclusion as you. I first thought the L2 was removing high frequencies, but it is in fact an LC filter to remove bass more efficiently.

That’s my question, how do I get rid of the crossover. In my limited understanding of electronics, the c3 capacitor will do nothing if terminals 11 and 12 are open. I’m not sure though.
