The overall audio is a clean and realistic reproduction.

Assembly


assemble 1

Note:- The two 60mm Assembly spacers have both ends of the down side chamfered to prevent them from becoming glued in place. After the sides are glued in place a 60mm length of 12mm X 12mm pine Tri-Quad is glued in the bottom end of the port. This, combined with the chamfer on the inside of the port exit, smooths the air flow from the port.
