Procedure

Applicable Paint Types

PL Series speakers are painted then coated with a Polane finishing layer. To paint over this finish, compatible paint must be used to ensure proper adhesion and finish.

  • Polane Polyurethane Enamel: Using another layer of Polane paint is a safe choice, as it ensures compatibility.
  • Epoxy Paint: Epoxy paints can adhere well to Polane surfaces, providing a durable finish.
  • Acrylic Urethane: This type of paint can also be used over Polane, offering good adhesion and flexibility.

Required Tools

  • Power Drill
  • Putty knife
  • Flat screwdriver
  • Hex no. 2.5 mm

  5. Fully mask the back of the grille.
  6. Wash the enclosure and grille with mild soap and hot water and rinse with hot water. Be careful not to allow any water or soap into the input, woofer, horn, or port. Allow them to dry thoroughly.

  15. Allow the painted enclosure and grille to dry for at least eight hours before handling.
  16. Remove the masking from the back of the grille and spray it with a light tack adhesive.
