Unfortunately far as I know coffee sonication produces horrible results. If I remember reading correctly the sonication produces a lot of cavitation on the surface of the grounds and leads both to the extraction of horrible flavours as well as the suspension of micro-fines in the brew that never settle. The reputation is it being undrinkable.
