Ok, this is the situation.   Sometimes, I havent noticed when exactly; my subwoofer (Intimus 8") seems to disconnect it makes a sound, similar to a click and stops with its particular boom sound.   I have an Intimus Set with an Onkyo 805 Amp.   Any help is greatly appreciated.   Regards Juan  

Hello,   When I received my S8 Subwoofer, some bronze knobs arrived with it, question is: I have no idea for what the are, does anybody know where do I use them?   Thanks   Juan
