Beovox S55 Bang and Olufsen Woofer Replacement (easy)
Step 1: Check your woofers, mine were shot
Lay speaker on it's back. Use a phillips to remove 6 screws holding the entire plastic speaker face onto the cabinet. Seperate. Lie the black plastic faceplate on the ground, with the speakers facing down. Snip the wires to your woofer, as closely to the woofer as possible. Remove the 4 phillips screws holding the clamps onto the woofer. Now, compare your old woofer to your sweet new one!
Step 2: Modify your new speakers for B&O use!
Silicone! Just squeeze some silicone caulk into the holes, and even it out. It doesn't have to be perfect, as it's soft enough to conform to the cabinet.
