When there is a shortage or spike on the electricity my old Definitive Tech sub was making a "Boom" sound which is really disturbing and probably harmful to sub.
And after a few years it started making a loud hum.
So, in my new setup i am thinking of plugging the sub (Focal SW800) to a UPS, to avoid that boom sound and possible harm it can do.
Do you think its safe and/or useful to do so?
On my setup, what else should i use with UPS?
Have total of 8 outlets from two 1000VA APCs.
