i already sold my sm3.
i think, ill stick now to the fx700...
im planing on pairing the fx700 with the ZO personal subwoofer.
and im gonna post another impression.
(i wanted to use the ZO to the sm3 to boost its sq -bass, highs...but its already on its way to its new home. just a thought.)
this will be interesting, even more bass boost with the JVC? if the ZO actually improves the bass quality and not just quantity of the JVC's bass, would definitely look into it, but kind of hard to imagine the FX700's needing any more addition in the bass departments.
