My point is that the speaker is designed and engineered to be operating symmetrically about its mid-point. (imagine a car that always pulls to the left - it's harder to drive...OK that might be a rubbish analogy).
The point is that a speaker in a cabinet which has a resistive loading (air in the box) behind it and a different resistive loading (air in the room) in front of it, the designer will be expecting to compensate for the difference between the two and the impact that has on the movement of the cone. If we move the nominal zero point forwards or backwards with DC we change the rules of the game in a way that the designer could not expect and will not have compensated for. Of course, in passive x-overs the DC will have other effects and I'm not sure if they'll be directional or not...that's probably another thread. Anyway, I think you're right about the WAV. If someone's got a suitable editor could they try it? You'd need to make sure the pk-to-pk volume is the same, with and without the "DC" offset of course... (I've just checked my system with a reasonably accurate multimeter and there's no DC across the speakers) -- Phil Leigh ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=22118 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
