Question about Bose Companion III Computer Speakers
I have a bose companion 3 series 2 multi media speaker system. every 14 seconds, the bass box lets out a 'whoomp'
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.
