subwoofer started farting (1 Viewer)

[Shayne Lebrun]

Recently, any time I turn my reciever on or off, or whenever a new sound source starts, or I switch inputs, my subwoofer emits a thumping sound. A single, tight 'whump' noise.
I didn't change anything; something, of course, must of changed. Any ideas?

this might be a receiver related issue. The receiver is supposed to mute the woof output for a millisecond when you switch inputs. I've seen a few complaints from Denon owners about this recently. I think Denon admitted a circuit failure and will fix the issue?

Did you start a high fiber diet recently?

Sadly, 'tis not a Denon. 'Tis a Pioneer.

Too many beans?

Too many beans?

Try Bean-O.

I'm having the same problem with my new Marantz receiver and my existing JBL subwoofer. The best I can find out is it's involving a DC charge built up in the sub. I now turn down the subs level before turning it on. It's a bit of a pain since everything else can be run with the remote.
