The cabinet consists of 19 mm boards and a 16 mm thick double baffle. The side panels of the medium range chamber are, at the same time, cabinet stiffeners. It is for this reason that the boards are "T" shaped. First of all, make the necessary cut-outs in the cabinet panels and especially the chamfers on the double baffle. Once the speaker has been completed, cut out the spaces for the woofer and the mid-range drivers. Finally, fit the speakers into the cabinet.

The damping of the speaker uses half a mat of damping material pushed into the medium range cabinet. The remainder is pushed into the bass chamber.
