I recently got a pair of Mission 702e speakers to replace my 700s, which are now being used as my surround speakers in my setup. I also have a Yamaha DSP-AX 620 Amplifier. I have a problem which im sure should not be happening. My 702e's can take power upto the -23dB mark when listening to something with a lot of bass. When turning the bass down completely, I can get to -17dB. Anything more and the speakers distort madly. I am having a guess that -23dB is around a quarter volume as my 700s used to distort at around half volume when connected to my old Sony TAFE-230 amp. Surely, this cannot be right, as my 702e's should be able to take more this this as they have a power rating of 100w/pch. I have the bass/treble settings set to flat and the 702e's set as the LFE channel. Please help as Im really annoyed with these speakers. Is this right for these speakers or am I doing something wrong? Thanks.
