The dustcaps on my Beovox 5700 have started to crumble and one has a bigh hole in it. I have asked Martin if he can send me new ones but in the meantime I was wondering if I can still use the speakers? They are at my parents and my mother is upset because I said she can't use them. If its going to cause damage I'll go over there and disconnect everything till they are fixed. She said I must ask Beoworld cos only they will know!!! Huff!!
