I'm having an issue with my subwoofer AGAIN.

I'm having an issue with my subwoofer AGAIN. On Friday 10, late evening I was watching tv, I notice my subwoofer suddenly sounds louder and boomy. I hadn't touched any setting or even touched the volume on the receiver. But I did check the settings within the receiver for the sub after I encountered this problem, which has no kind of EQ which was correct and the vol. set +2.0db, which was also correct. Also checked the volume knob on the back of the sub itself, which is set at the 50% mark, the middle where it's supposed to be. I don't know exactly what is wrong. I could use some help.

Just for TV or with every input?

It's a VIRTUAL channel unless stated otherwise.

Some shows/channels are bassier than others.

Or it could be a loose wire.
Or it could be dying.

I would rule out the source first, a lot of Low frequency effects on TV shows are horrible. See it you start noticing a pattern in certain shows.
Some TV shows we have to watch in direct mode the mix is so bad. Perhaps these embellishments are because they figure most folks have soundbars, or the sound guy has a sound bar!
Don't use TV or streaming sources or first generation CD's to EQ your equipment you don't know what you are getting.


That's the problem with high quality gear Garbage in Garbage out!

Music, more music.

The potentiometer may have developed carbon inside it. Try using just a drop or two of any good contact cleaner inside the potentiometer, give it a thorough whirl in either direction, let it dry completely, then check again. Hopefully this should fix the problem. (Remove power cord from the mains before cleaning the potentiometer).
