Two omnis, separated by a small distance, and subtracted, _do_ give a figur=
e
of eight pattern.  The only trouble is that the frequency response is
differentiated.  So it rolls off towards low frequencies at 6 dB/octave.  I=
n
order to get the response to be flat again, say over the 3 decades of the
audio spectrum, would require 60 dB of bass boost.
