If you mean front panel (cloth) removed, there will be only the two speaker elements (second picture Login to view image Login to view image Login to view image

Thnx very much Lausvi. you are completely right. I wanted to see the interior. And as I haven’t had my hands on this BeoVox type yet, I wasn’t aware that the back panel had to be removed to get there. So thanks for understanding that. If I may ask … In picture 1 and 2, the two pieces of white foam van be seen on the right. What are the dimensions of both pieces? (W x L x D)

No worries ? Unfortunately I don't have access to the speakers now (I sold the BV3000s and upgraded to BL45000s which are the same size but are currently in storage) so I can't check. However as the BV3000 specs say the speakers are 45 x 38 x 8cm (W x H x D) one could perhaps approximate the size of the foams form that. I think they had a white fabric on the outside but felt like foam on the insde. There is also a foam tape -like gasket. It's the black tape on the first picture and green on the second as I had replaced it. Not sure if totally necessary but the old stuff was crumbling and I had something close-enough at hand to put in there. Are you trying to make new acoustic foams?

Thanks a lot, perfect. Yes, with the dimensions that are known and your pictures, I can estimate all other dimensions. That will work.  

I am late to the party, but what did you use for new gasket? lausvi wrote: There is also a foam tape -like gasket.

It was just double-sided foam tape, couple mm. thick. It resembled the original and it felt like it would do the business.
