Hi and welcome to FixYa,

Appreciate the direct "Ask Me".

Initially, the 14 seconds interval is significant. This is indicative that whatever fault it is, it is coupled to a time-based circuitry. The time-based circuitry need not be complicated. it can actually be a simple resistor/capacitor network. The capacitor takes a certain amount of time to charge and then discharge (14 seconds, 'whoomp'). Having said this, then the foremost suspect would be an electrolytic capacitor, probably low value (1~4.7uF), probably a coupler/decoupler. Of course the capacitor serving other functions could very well be the culprit as well.

Corrective measure would entail, identifying/determining which capacitor and replacement. Tedious as it may sound, each capacitor would then have to be tested for capacitance and leakage out of circuit or at least 1 leg un-soldered.

Good luck and Thank you for using FixYa.

Pls be informed that due to my current rank and rating, even a Helpful would be detrimental to my status. Should this solution not address your concern, it would be appreciated if you could just not rate it at all. Cheers.

Bass rattling on Bose Companion 2


My Companion 2 speakers were having the same problem with the rattling on certain frequencies and I am happy to say that Steve Allison was correct in my case. The speakers don't handle surround settings very well so if you're running your speakers through a source that had that setting turned on the easiest way to stop the rattling is to just turn the surround setting off. The speakers weren't really made to handle that kind of a signal.

Loud hum when Bose Companion 3 Series II speakers are turned on.


I had the same problem for many months. I asked a sound & video professional and he suggested I move the subwoofer away from any power source. I had the subwoofer next to my UPS. Once separated and moved all wiring away from the power supply (about 12") the low bass hum was practically gone.
