I have a friend who I told needs to buy the dts-10. He bought one and took some time to put it together. He has owned many of the great subs mentioned here on the sub forum. They include the dts-20, conquest, a7-900, dual Klipsch THX subs, DIY ported and sealed, other eD subs, SVS PB13 ultra, etc.... He has not dialed it in yet but his first impression was "this thing is ridiculous". Those are some awesome subs and to say that is impressive.
