Hi,
I hope this message reaches you well, I know it's an old post. I recently bought some old Beovox Penta in average shape and want to restore them. My project is to run them in active mode. I mean running them in a three-way system with active filter.
From the previous post, I saw Niston switching the rotten mid speaker with visaton. From the pdf description, the outer shape doesn't match the circular shape from the original speakers. https://www.visaton.de/sites/default/files/dd_product/frs8m_8.pdf How can the Visaton speaker can fit in the old speaker's place ?
Another thing, I have lots of problems removing the covers without any damage, any tips ?
