On a side note, are you using any signal processing unit between the sub and avr like BFD, SMS-1, mini dsp, etc?
I'm not sure how to turn the sub off first if the sub is set to auto turn on/off?
Also, no signal processing unit between.
You should have a button on the sub to manually turn it on/off apart from auto on/standby toggle switch.
If you take yourself too seriously expect me to do the exact opposite
I have had two Monitor Sub 12s. My current one as well as a loaner store demo unit while mine was on order. The pop you describe when the sub detects a signal and the softer one when a period of time has gone by with no signal both seem to be typical of the model. I have my receiver set for a low initial volume on start up and for me the sub only wakes up once the first audio signal reaches it. I don't find it bothersome.
The Laws of Physics aren't swayed by opinion.
I decided to send Paradigm technical support an email to find out once and for all what is going on. Below is their reply.
There is a high current amplifier in this subwoofer so a small pop when turning off or on is normal, as long as the subwoofer doesn’t pop while music is playing through it you are fine.
I'm going to go with that. I guess/hope problem is resolved. Thanks to all who chimed in.
