Are the Axiom Subs "active" is that the right term. i mean do they have a separate power supply. If they are, do aiom make an australia power compatible version. and do the other companies such as HSU and SVS also make subs compatible with the australian power supply. The power supply issue (and lack of money)are the only things really stopping me from buying all this stuff.
