Altern

45、ately, if the packing foam is not available, the speaker must be supported so the base faces upwards in a clamp so it can be worked on easily, taking care to pad the clamp so the enclosure will not be scratched. 2) Peel off the four rubber pads on the base cover. 3) Remove the (4) Phillips screws th
