I finally made them. My first project ever. It wasn’t easy, especially the cutting of the MDF and the milling but I did it. As said I wanted to avoid putting a subwoofer, so I increased the volume to 35 liters and tuned the bass reflex to 65 Hz with Winisd.
They sound incredibly good although the changes I made probably worsened the initial design 😉
Thank you
Enrico
