Hi Frenchy and thanks for your tip :) i'll try to use that next time hehe, btw i recognize you from the Zbrush forums.

Michael: Only two parts of that model once used to be blocks but i converted those into normal objects, maybe it didn't fully work. But still i don't understand why the speakers body is duplicated and moved up a bit as it's not a block. I also noticed the foot is duplicated but it's copy remain in the same place as the original. However i'll email you a copy of the original file from Rhino so you can have a look at it Michael. Thanks for your quick reply as always. :)
