Question about Bose Acoustimass 15 System
I have an acousticmass 15, and the subwoofer emit a hummmm even when it is totally disconnect from receiver and speakers, The Bass control of the module appear to be a little loose when I twist the control the hummm dissapear, maybe I need to change the bass control but I don't know the type of control. I remove the cover and everithing looks well no disconnections or bad soldered joins apparently.
so far from the information gathered from you, it sounds as if the control knob mechanism in the unit itself is going out. the fact that it adjust on its own, and the humm indicated that the position sensor in the control knob is malfunctioning. If at all possible visit the manufacture's website and there should be a search bar once you have searched for and found your product, there will or should be a link to help you purchase parts and accessories for the unit. I hope that i have been helpful and this fixes your problem. any diagrams or instructions can be found on the manufacture's website. if you are still unable to complete/fix this problem with the information available or that i have provided let me know and we can take further action at that time. but my main suggestion is to replace the internal working component of the control knob.
