Assembly Instructions:

  1. Carefully remove the cabinet from the packaging. Locate the raw damping material inside the cabinet and set it aside.

  2. Cut the raw damping material into 18 pieces according to the cutting pattern diagram.

  3. Place each damping part into the cabinet according to the position diagram. Add a bit of glue if needed to hold the damping in place.

  4. Detach the pedestal by loosening the four screws under the speaker cabinet.

  5. Place the crossover onto the top of the pedestal, with the input cables towards the rear terminal side and the speaker wires towards the front panel.

  6. Pass the four pairs of speaker wires through the holes in the bottom brace of the cabinet as shown.

  7. Pass the input cable through the terminal hole on the rear of the cabinet, then connect to the binding posts.

  8. Mount the terminal panel onto the terminal hole at the back of the cabinet.

  9. Mount the pedestal with the crossover to the cabinet. Make sure to gently tighten all 11 screws without overdriving.

  10. Guide the four pairs of cables through the holes in each cabinet bracing. Pull the tweeter and midrange cables through the midrange chamber partition hole.

  11. Seal the cable holes on the midrange chamber partition with hot melt glue.

  12. Hook up the cables to the woofer, midrange, and tweeter terminals.

  13. Mount the drivers to the cabinet and gently fasten the screws. Take care, not to over-tighten.
