Subwoofer out of phase

My toddler enjoys fiddling with my system.  He recently pulled out the cable to the subwoofer.  Without thinking, I tried to re-connect it to the subwoofer without turning it off.  I heard a loud thump before even being able to connect the cable.  When I referred to the owners manual, it turned out that I was trying to connect it to the wrong input.  I turned off the subwoofer and connected the cable to the correct input.  I decided to do a speaker calibration just to check that everything is ok.  I got a mesage on the screen that indicates that the subwoofer is out phase -2.0db.  Does anyone know what this means and what I can do to fix the problem?

RE: Subwoofer out of phase

What sub is it?

 

Do you have a phase button on the back 0degress / 180 degrees or a variable knob that says phase?

RE: Subwoofer out of phase

Does the calibration say it's out of phase or did it set the sub -2dB lower? Or Both?

If you have a phase dail on the sub, just put on some music a movie and listen how it sounds with the phase a 0 and 180. The one that gives you the most bass is normally the right setting.

 

And btw, Audyssey always said my CS center had switched polarity, even though it didn't.

RE: Subwoofer out of phase

I believe these incorrect warnings can be addressed by moving the setup mic a small amount. Probably room acoustics?

Thanks for your response.  The subowoofer is part of the Monitor Audio Silver RX6 AV12 speaker package.  I don't know if there's a phase dial at the back.  I will check when I get home tonight.

Thanks for your response.  The calibration indicated that the subwoofer was out of phase.  I will check the phase dial later.

Maybe your toddler fiddled with that as well and changed it - thats why I mentioned it, there is a good chance

Hello BJB,

Once you've solved this little local difficulty, what are the chances of your keeping your toddler AWAY from your kit in future?

It's a good point SJ, but unfortunately we have an open plan living area so I cannot close off the system from him.
