Re: Low volume output from subwoofer

Here are some more pictures. I noticed on the back of the PCB that the soldering seems to be sloppy on some points. Some resistors or capacitors seem to be solder together on the + and - wires. It's noticeable in the upper right corner on the first 2 pictures, is this something I need to worry about?

I also scrapped away most of the glue and it changed nothing.

I also noticed that the woofer cone seems to flutter a little when I move the Gain dial....

Re: Low volume output from subwoofer

Under the bigger capacitors is that also glue that should be removed? Also whats the best way to remove the glue?

Also when I turn it on it flutters for a little bit before settling down.

Re: Low volume output from subwoofer

Will do that as soon as I get home. Thanks for the input guys.

I've got a KLH ASW12-200b subwoofer that turns on and outputs sound but at a really low volume. I have to max my bass, treble and subwoofer levels in my AV receiver as well as putting the gain to max to get any useful sound out of it.

I have checked the RCA plugs and they seem fine. But I noticed that some capacitors on the control and power boards seem to be leaking? I'm a newbie when it comes to these types of things so I would appreciate some input from you guys on the best course of action to fix it up.

Below I have attached pictures of the caps that I believe...
