Question about Mission 780 Main / Stereo Speaker
If these are Mission 780s your talking about, you're not the only one. The woofers supplied with the speakers originally have a known design/manufacturing flaw causing them to go "open circuit" after a few years use. The good news is that IAG (who now own Mission) can supply you with a pair of replacements for about £45 plus postage. (You'd be forgiven for thinking they should supply the replacements for free given the cost of these speakers new and the fact this is a design/manufacturing fault). Replacing your woofers is easy. Take off the front baffle. Remove the four rubber plugs that the baffle attaches too, and take out the 4 screws you'll find behind them. Now ease off the plastic moulded front pannel. Remove the four screws holding the woofer in place. Pull the spade connectors from their tags on the back of the speaker. Put the new woofer in by following this proceedure in reverse.

First, check if the speaker coils are blown (open Circuit). Take a multi meter, and, after removing the cales connected to the speaker, check for continuity. Reading should be either 4 or 8 Ohms. If there is no continuity, then there is nothing you can do except get a replacement. There is no need to get a technician to to do this basic check.
