The jack: it is introduced on the potentiometer, it therefore can not change it (if the jack is dead, it will be necessary to cut the cable, put a jack .... rather than simply buy a cable ). Same for the speakers, it is not two copper son satellite but normal setting => Encore difficulties if we want to change the speakers, you will have to buy a jack, and mount. => In short if you are a handyman minimum ca goes largely, but it's still a little annoying.
But everything else is really excellent: - potentiometer for setting the bass, very good design.
