I have to take issue with the assertion that "Monopoles produce a simple radiation pattern which is non-directional". A typical direct radiating loudspeaker system with a dome tweeter and a cone woofer mounted on a box is NOT non-directional at all! At least not until you get down to frequencies whose wavelengths are longer than the baffle's dimensions. But it most certainly is a mono-polar device.
As for the output of dipoles vs. monopoles, I have to think you are perhaps not factoring in the room contribution to the overall perceived sound. Your formulas are no doubt assuming free space measurement. But indoors, in relatively small rooms is where most people actually listen to music in their homes. And in those enclosed, reverberant spaces it is a vastly different acoustic environment, and in fact the inverse square law no longer accurately describes the sound field. -- jdm56 ------------------------------------------------------------------------ jdm56's Profile: http://forums.slimdevices.com/member.php?userid=9919 View this thread: http://forums.slimdevices.com/showthread.php?t=38593 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
