Hi, The speaker seems special in the Beomaster 800, it has a 50R resistor built-in and is hard to find a replacement for. I have a BM800 where one of the speakers are dead (infinite ohm across coil), so either I find a BM800 I can take the speaker from or I find an ordinary speaker (e.g. 4 or 8ohm) and add a series resistor to it. Do any of you know where to find a replacement speaker (it is 13cm wide and 7,5cm height). I have also tried to see if other Beomaster have the same speaker, but cannot find any - or have I overlooked something? /Pindsen
