CONCORDE MK III
All the boards are cut to size and glued (butt-jointed) as shown in the parts list. Particular attention must be paid to the front panel, because the first thing here is to apply the 45° chamfers. We recommend cutting and finishing the openings for the drivers before the cabinet is assembled. The cabinet can now be glued together. Ensure that the mid-range surround is tight against the front and side panels so that no join is visible later.
Once the glue has dried, the 45° chamfer is extended onto the side panels. This must be done extremely carefully so that none of the edges break out. The best way to finish of the chamfers is to sand them. Drill three 8 mm holes in the rear wall of the mid-range section for the cables. Ensure that the holes are well sealed again when the cables are in position.
The crossover can be mounted on the strut behind the lower woofer.
One and a half mats of damping material are required for the mid-range cabinet. This is best done if the damping material is cut into six equally sized pieces. The remaining eight and a half mats are loosely but evenly distributed inside the bass cabinet. Begin at the bottom, immediately above the bass reflex tunnel. Leave the space behind the bass vent free of damping material.
