I realize my faux pas' mentioning another manufactures product ..oops, my bad
I don't think it's wrong to ask about KRK subs here.
Is it working well? What monitors do you pair it with?
The sub doesn't light up the front facing logo like the studio monitors do. I searched for the sub on youtube and found a review where someone had the monitors and sub on the same desk. The rear power indicator near the left side opposite the power connector/switch is it.
There's a KRK forum here: https://en.audiofanzine.com/active-monitor/krk/forums/
