My install of GR-Research Klipsch networks, tube connections and no Rez! Next set I would urge myself to use the top position on the binding post plate. The bottom position does not leave much room behind it. Board length will be critical! Don’t go longer the 6.5 inches. Or 6 even. I used 3/8ths cherry hard wood as my network board, and used gunstock stain with NO clear coating. I also added a few more bits of no res to places, front of network and rear.. back walls too and bottom. I also re-glued the cabinets.
