thank you all for your fast answers!
And yea, it's like thisgsx said, I can just hear out, that the center is too small for the fronts. But as I said only at music. If I would use my system for 100% HT,
I think there wouldn't be so much a problem and I would let it like it is.
I also thought that the front is just glued.
My idea is (I think it would be the easyest way) just to remove the front panel and make a new one for the other positions. The rest of the cabinet i wanted to let like it is,
so that there is not so much work. I never builded a complete speaker by myself. I would like to, but as I'm living in a normal apartment with family, there is no space for me, for such a
big project. But just to change the frontpanel should work I think.
Do you think, this would work like that?
