I'm currently refitting the Cinema Room, replacing Receiver, main speakers etc and will be moving the DB930 and Mission 733(Floorstanders 10yrs old) into the living room where the missions will have to go right next to the TV. These speakers aren't magnetically shielded but I found that if I held a biscuit tin lid between the speakers and tv, that the magnetic distortion on the screen disappeared. So my question is what type of metal sheeting do I need and where could I purchase it and have it cut to the right dimensions?? Also, there doesn't seem to be any way to access the inside of the speaker bar unscrewing the main speaker driver. Has anyone opened up their speakers? Are the internal wires unplugable, ie will I be able to get the driver out of the way without damaging the internal wiring? Ideally I would like to put the shielding on the inside for aesthetic purposes but if this isn't possible I can accept putting it on the outside and painting it black to match the speaker colour.
