Mission speakers...i think i've blown one of them...

Bad capacitor(s). Happened to mine too. Opened it up to find 2 completely blown apart, and 1 bulging. Relatively cheap and easy to replace.

Hi, yes there is a rather simple method for testing the actual subwoofer unit, simply plug in a known good rca cord into the input-make sure if there is a switch for level input that it is on the back make sure it is switched to line and not level, next plug in rca cord, turn on unit-stick tip of finger on tip of rca cable. This should gernerate a"HUMM" in the subwoofer if everything is working correctly. Thanks for choosing FixYa, I hope this was of some help,good luck Prodzilla.

Just connect a 1.5 volt battery to the plus and negative terminals. You should hear a pop in each driver.

if you have access to a multimeter, you should test you impedance (ohms) Ω, check to make sure the speakers reads higher than the amplifier needs; this will result in less strain on your amp and diminishement of sound...For example: if you connect two 4Ω
speakers in series it results an 8Ω circuit (least strain). and if you'd take the same two speakers and connect them in parralelle it would result in a 2Ω circuit (most strain).

I would try ebay first. If not follow this link to see if they can help you out. Mission ltd is located in the uk. http://www.mission.co.uk/

Silly question but did you check the fuse and if so is the sub pluged into the sub out put on your amp and not the sub six channel input as this will result in no sound.
hope this helps.
CABLE GUY.

i had the same thing it is a problem with the flux that was used on the drive cone to connect it to the outer case had this with both speakers change the drive cone.

Did you try a different sub cable? Does your receiver have a "night mode" where the bass is reduced? If it does make sure that it's not tunred on. I hope this helps.

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.
