Hi everyone, I have the base model EV3 and I love it. Unloading the back I noticed that there is a speaker grill which I assume is where the subwoofer lives on higher level trim ...has anyone with the base model been brave enough to look behind the curtain? Or should I say the trim.

Is there wiring? A bracket for the sub? Or is it just and empty hole of disappointment?
