All, Greetings. I've had my system set up for a couple weeks now and everything seemed to be moving along quite smoothly. Last night while sitting around the HT room (nothing on the system), my subwoofer let out a low growling sound for a short moment. Later in the evening my son reported the same thing happening.
I have the sub plugged into a separate power source from my other components. Should the sub be left on when the system is not operating / or should it put turned on and off accordingly? is this what made the thing growl?
There can be a number of things that will cause it. One thing you can easily do is to make sure the connection is tight.
The last time I heard a powered subwoofer growled...the cause was the capacitors leaking. Normally a subwoofer should not make any noises, even for the type that doesn't auto-shut-off.
In your case since it's new...my guess is your connection is loose.
Hank, Thanks. I'll have a look at it when I get home this evening. It is a VERY inexpensive powered subwoofer that I purchased simply as a starter unit. Once I can reload financially from my initial HT / Basement remodel, I'll probably be looking to upgrade the sub. Until that time, I'll check the connections.

* since it does not have an "auto shutoff" that Stof mentioned, should I just go ahead and power it down whenever I'm not using the system?
