Hello.
The most likely cause is the Crossover unit inside the speaker has failed, It is possible that a wire has come loose also inside the unit. The Crossover unit is what separates the High Frequency sounds from the Mid and Bass Frequencies, if this unit has failed or a wire has come loose then it will cause your problem.
By Unscrewing one of the outer speakers you should be able to see the wiring. trace the two wires from these outer speakers back to there first join, make sure it is connected correctly.
There should be two wires coming into the back of the box, then directly to the crossover unit. from this crossover wires to each individual speaker.
I hope this helps your problem Regards GM

No sound from the main cone mission m73


It sounds to me that there is something wrong with the crossover unit inside the speaker. These tend to use non-polar capacitors these sometimes fail, but it depends on how sophisticated the crossover is. It could use semi-conductors as well, which also fail.

Recently one of my mission 782 side bass driver has no sound, is it dead? Do you have any idea where i can get the driver to replace? and is it difficult to replace by myself?


Drivers are easy to replace in most speaker systems. There will be 'spade' type push-on connectors to the drivers. Here are contact details for the Mission service centre in the UK: http://www.mission.co.uk/Distributor.aspx?lang=En&Tab=29 They should be able to supply you with a replacement.

Do i have to remove the pin between the two speaker treminals on my old mission 780 speakers before i bi wire them


Yes, the two sets of terminals are for the tweeter and bass driver.

When you bi-wire you want the low frequencies to go only to the bass driver and the high frequencies to go to the tweeter..

Please see this link for more information:

Only bass driver working on the pair. tweeter and mid range cones not working.


hi,
check the tweeter and mid range. its coil may become faulty.
for checking the speakers carefully remove the speakers one by one, remove its connections.
and check the speakers with a AAA cell. is it producing cracking sound. if not the speakers coils are burned.
ok

I bought replacement drivers for Mission 780 speakers...how do I replace them...no visible screws...does the cover plate come off?


Screws are hidden under the plastic plugs where the covers slot in. remove cover, then maybe use a pencil and fingers to prize out the rubber "holes". Once all four removed, unscrew the four screws visible. Carefully lift off baffle, note that tweeter will be attached to the baffle. You then have easy access to the driver, again another four screws holding that in. You may find erosion on the terminals.

Mission 780s (from early 1990s) tweeter gone?


Hi there.
Do you have the make and number on the back of the magnet?
Check if the tweeter is at all available on the net!
To have it repaired is also an option.

Removing Driver from Sealed Cab


1. Remove the front cover.
2. Remove the four bushes that held it in place. Beneath them are crosshead screws.
3. Remove these screws, and the surround board they hold.
4. You can now see the bass speaker retaining screws. remove them and withdraw the speaker *carefully*. (A knife under the edge helps to get it going.) The wires are at the back mixed up with the damping wool.
5. The tweeter has its retaining screws under the rubber gasket stuck to it.
6. The connectors shoud slide off the lugs, but mine are pretty stiff. Careful with the tweeter's: mine pulled out the termnal completely, and I've had to replace the unit!
