Thanks - I will.

You're still confused. A monopole is *spherically* symmetric, not cylindrically symmetric. It radiates sound equally in all directions - up, down, left, right, back, forward. Again, try to imagine a little sphere that grows and shrinks, grows and shrinks. I agree with you that no loudspeaker has that characteristic, nor did I ever claim so (and neither did anyone else AFAIK). Enclosed spekers *do* come close to that at low frequencies, however. And irrespectively of whether any given speaker is exactly monopolar, the power of that description arises from the fact that any sound field, no matter how complicated, can be decomposed into a sum over multipoles, much like any waveform can be decomposed into a sum of sine waves. Since acoustics are close to linear, a sum is a useful representation (because the different multipoles don't interact). -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=38593 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
