Hello,

Just curious about speaker calibration. Video Essentials and S&V test CD says 75db, while AVIA says 85db, is there really a standard on that? Can I use 80db instead of 75db or 85db? Also, is there any possibilities that the speaker will break if you reaches the Speaker Calibration Level of your Receiver to MAX (such as mine is +15db) ? Anyone would like to share their thoughts?
