The konaki motor is not the same as the hdc3, the gap on the hdc3 is wider. (different coils)No, There have the same motor as the Audioque HD3C.
Also, shares motors with a American Bass sub, XFL i think.
But the Konaki soft parts are terrible.
IMO, its a waste of time. Just go buy a Audioque for a little more money and have a whole quality sub.
