Unfortunately the pinwoofer kits are poor quality made in China. The soundbuttons feels cheap and not accurate at all. Further he dont accept his own product to take back... When I started about a review he comes up with an vague proposal to end up still stealing money from me 
The pinwoofer set add nothing to a premium or le. If you have a pro just swap the backbox and cabinet speakers. You can easily do settings in the menu and you don't need such a clumsy poor quality equalizer for that.
