To remove the grille from your Alpha B1 speakers, insert a hook into one of the holes in the grille close to a corner and lightly pull on it. It is best to work your way around the grille at each corner when removing it. If you just pull on one corner to remove it, you may end up bending the grille.
PSB Offers a grille hook tool to assist. Please submit a request below to contact our Support Team to learn how to acquire one.
NOTE: The Alpha B1 and Alpha B use an identical metal grille though the model logo will differ.
