Subwoofer pops when turning off..

[jazzisnumberone]

I seem to have a problem here. Whenever i turn off the subs in my HT system there is always a popping sound coming from all of them. The volume control is turned down first then i may wait until 1/2 hour before i unplug and it makes that obnoxious sound. I don't want to damage them. I disconnect it when i go out of town. Am i damaging them by doing this??

I'm not sure what is up with that but you might mention what kind of sub and rec'r you have. My computer speakers do the same thing when I turn the computer off but only since I put a sound card in. My HT subs are quiet while being unplugged. I ran across this write up by The Trixta recently that is not directly related but talks about how the internal wiring layout can affect the subs:

They are Def Tech pro Sub 80's. The receiver is a Marantz SR 5200 AVR.

Mine pops when it turns on and off which is normal. It is just woofing and it is a subwoofer so it has a right to do this.

Thanks. I didn't want to mess anything up. The first time i heard it i thought i did some sort of damage to them. Thanks for the response.

Well, it might not be normal depending on how loud it is. My B&W sub makes a very subtle and quiet noise when it turns off. My PC13-Ultra originally made an extremely loud noise when it shut off (so, like you, I thought that it might be damaging something). So loud that it made the pooch go hide and not come out for a while. I ended up setting it to always be on. SVS recognized a fault in the amp design and has since had the amp supplier redesign the amp. That type of shut-off pop is NOT normal.

So the bark "woof" is worse than the bite "ruined sub"

Adam has a point on how loud it is. Mine is the same, which is a very soft "thump", no matter what the volume level is, which is normal.

Mine too...and we have the same sub (for now)
