Good to hear from you. Hope all is well.
I’m half way done with my servo swarm. 2 fronts done and boxes complete for the back 2.
If I remember correctly, you have a preamp level controller that has a volume pot and some kind of subsonic EQ for these. It would be nice to know a bit more about that box. Not sure if it had amps etc.?
If it will work with the PEQ 370 servo amps (low voltage/rca input) I would be interested in one.
