Ironically, that skewing effect may be one reason why the

Yet Stanley Lip****z, Mr. Ferstler, with whom I am
acquainted,is
a fan of the Quad ESL-63 loudspeaker. Isn't _that_
peculiar.

Just goes to show that even the editor of Stereophile
doesn't understand that the well-known fact that the Quad
ESL-63 is a made out of a collection of smaller diaphragms,
each small diaphragm independently driven by a tapped delay
line.
