    Now got mission 702e wired upto my old stereo amp Pioneer A-300x,rated at 50 watts.

    Pioneer is linked to yamha amp, so speakers have been tested with dvd signal from yamha and music from marantz linked directly to piuoneer amp.

    Speakers start to distort at dial 1/4 turned, specifiaclly its the top speaker that starts to rattle and make satanic noise if its vibrating of something,tried tighting up speaker quite at bit,still the same.

    Could turn pioneer halfway with mission 760is and they were tiny similar to mission 700.

    So to conclude its the speakers!!!!

    Anyone now how to fix this problem as it seems common.

    Searched net seems rattling baffle is known problem of speaker thet mission is aware of and will fix so ive emailed them.

    Hi,

    When I had my Sony TAFE-230 Amplifier I could get my 700s upto just over 1/2 volume. So that would be about 20 w/pch, not very good.

    Then, when I got my Yamaha amp and I tried the 700s on it, I could get them to -25dB without distorting.

    The 702e's can get to -20dB without distorting, but only with dance music on.

    If I try to play anything with continuous bass, the speakers distort and I have to turn them down.

    Piero Milani, what are you playing on your speakers, as if you let me know, I can try and get it and try it on my setup.

    Thanks

    My 700s used to rattle when I played them loud, and so do my 702e's... I haven't tried to tighten them up yet.

    Just in case you don't know... the top speaker is the bass speaker which does all the vibrating. The boxes were calibrated for this speaker, as the bottom speaker is the tweeter and hardly moves (probably not visible to the eye).

    Oh... I am pretty sure that the 702e's are not floorstanding boxes. They are bookshelf boxes in floorstanding cabinets. Try shining a torch into the bass port and look towards the bottom. I stuck a ruler in and hit what I thought was the bottom, and surely enough, it stopped.

    I have sent my speakers of to mission to be fixed, the 702e has a known problem with loose baffle.

    My speakers stated to rattle at relativly low volumes.

    As i said i linked my stereo(pioneer A-300x) amp upto the 702e speakers i could only turn volume up a quarter turn before speakers were vibrating.

    I could turn amp up to halfway with my old mission 760is(similar to 700), before speaker distorted.

    If your speakers start to distort at a certain volume then they are maxed out, if they start to rattle and vibrate then they have problems, so phone or email mission like i did, if u think ure speakers are defeactive.

    Try this test turn up speakers if they begin to rattle, push down on the baffle if this seems to help/stop vibration/rattling i think ure speakers are defective.

    Just incase u not sure what baffle is, its the hole that the speaker pushes air out of.

    My speakers were out of warranty, but they are being uplifted today and fixed free of charge as this is a defect in the speaker, the baffles must be sealed better.

    Mission were more than helpfull with me and very friendly so give them a call.

    My speakers make a terrible vibrating noise its easy to distinguish between a speaker that is distorting due to high volume.

    Hope this helps.

    Mission 700 are very small speakers, u can turn them up halfway with ure sony amp, this seems about right.

    My 702es vibrate at 1/4 turn with the pioneer amp which is rated at 50 watts, thats why i new sumpthin was wrong with the speakers.

    Any music makes them vibrate im afraid.

    Thanks :)

    My speakers started to rattle last night :( I tried tightening them up, but it didn't do anything.

    Are my speakers out of warranty now that I have tightened them up?

    I think I might e-mail Mission to see what they say?

    What is the cost to get Mission to come and pick up the speakers and repair them?

    Thanks

    Don't over-tighten the speaker cones. You'll damage the mountings. As I told someone else recently, it's a design fault on the 702e's where the front baffle comes loose. You can't fix it yourself, but Mission are very good at customer service and usually go out of their way to help. Phone or email them at their factory in Huntingdon.

    I also tried to tighten mine up, made no difference, hope u didnt tighten them up much it can damage the mouning point as its made of plastic.


    As far as cost of shipping them to mission, i wasn't told how much, so i assume its free.

    Phone or e-mail mission and they will arrange a day for them tobe picked up from your home.

    hope this helps

    Hi,i've had these speakers for a while now and had the same problem,where the whole front baffle comes loose and vibrates.

    Now if your reasonable at DIY you can fix it yourself by gently prising up the the wood surrounding the plastic baffle,you know ,the part that turns in at an angle,the edges of the finish will not split as they are all seperate on each side.

    Then you gotta stuff some wood glue round the edges of the baffle and work it underneath the edges of the baffle and wood.

    It has to be all held together with clamps or tape will do,left overnight or 24 hours and its fixed.

    Mines been perfect for months now,and goes as loud as i like.
    Took me about 1/2 hour.

    Personally i think it would be best to let mission fix the problem, your DIY sounds impressive ricky, but as mission are willing to fix for free i would advice anyone wity problems to contact mission ASAP.

    Mine are out of warranty and are being repaired free of charge.

    This is a known fault with some 702e speakers, IMHO the speakers should have been recalled.

    It was an inocent joke, a little humour makes the world a better place to reside.

    I actually cant believe such a light hearted joke was edited by the form moderator.

    I will remember in future not to submit any wise cracks, i will mantain a profesional manner at all times. :p

    Incase the humour police clamp down on me and ban me from the form which is excellent. :rolleyes:

    Hope ricky has not been permently scarred by my scathing comments, sorry m8.

    :D

    Yours sincerly

    Glad you guys sorted that out :)

    Ive just e-mailed Mission about my speakers, and am now waiting for a reply :)

    Ricky, when you say they go as loud as you like, does that mean that you can play them full volume? What amp do you have?

    Hi,i have a Marantz SR5300 thats rated at 90 watts,cant say i'd ever try full volume,probably hurt my hears.let alone my speakers,but yes,whatever volumes i wish to listen at,and sometimes they are high,the missions handle it with ease.

    How are the speakers doing?

    Im having mine picked up this thursday :) They don't seem to rattle badly, but just when playing them loud... it isn't distorting.

    I can't wait to get them back :D

    Hello M8,

    I still dont have mine back yet, mission must be adding gold plated custom woofers or sumpthin. :)

    As soon as i get them back i will give them the welly and report back, hopefully to say they went so loud my house subsided.

    wicked! :cool: glad they are ok

    mine have been picked up and i should get them back in a few weeks.

    yeah, i didn't think that they could take full power as the woofers are only small, but if they go louder than what mine did then it must be pretty damn good :)

    cant wait for mine! woohoo

    Got mine back a week after they were picked up.

    Excellent speedy service, although they seem to have a nasty dint in one of the speaker boxes :confused:

    What can I say? I have gained an extra 6 or 7dB since they have been fixed. They can happily take my amp upto -14dB when playing a song with bass and having all settings set to flat.

    When I turn on BASS EXTENSION, -23dB is about the highest before they distort, but I am extremely happy with them.

    Well done Mission!!! :clap:

    hmmm, perhaps every time you send them off to get fixed, they damage them on purpose so that you don't send them again :D lol
