covering for speaker cabinets, 150cm wide, 2mm heavy duty Felt. This felt is perfect for replacing old felt on speaker cabinets. It will make old speakers look new again. The felt itself is off good quality. You will need a contact adhesive to put it on. There are spray cans available which are very handy but are quite expensive. Either way you need to spray the contact adhesive onto both the felt and the speakers and wait for the glue to become tacky to touch. You can then cover the speakers with the felt. Use a small blade to cut the felt. I suggest you look on the internet on fitting instructions as none are provided.
