ESS AMT-1D speakers, as far as I know, do not use electrostatic
elements.  Rather, they use a dynamic tweeter in which the element
is accordion-pleated to provide a better impedance match to the
surrounding air than might otherwise be obtained.  I heard a pair
of AMT-1 (not 1D) speakers a number of years ago, and they sounded
somewhat muddy, but the -1D may be different, and, anyway,
chacun a son gout.
