Noticed last night that the woofer in one of my Mission V62 front speakers seems to have stop working, I get no sound from it at all, I only get sound from the tweeter(?). I've changed the speakers around on the amp and confirmed that it is indeed a problem with the speaker and not the amp. The speaker has been pulled about a bit just recently, nothing too violent, just generally moving it around to accomodate my new plasma. I wonder if this has done something as simple as dislodged a wire inside or something. Is this likely? Is this something that should be easily repaired? I've had them just over a year and I know Mission have a 5 year parts & labour guarantee, so I suppose first port of call would be the shop where I bought them? Or is it something I could do myself?
