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.
