Hey @erik_squires , how is the project coming. I have a powered center channel (Paradigm Active CC) below my screen and a passive one above it. The active has a volume knob on the back, a high pass filter, bass and treble contour knobs and both XLR and RCA inputs. You can see the specs using this link:
