If it were me I wouldn't try a new method using genuine speaker cloth as I've said before, I wouldn't try it in a speaker/radio cabinet either, any old piece of board with a cut out would be my choice for trying the unknown out. The last time I clothed up a speaker cabinet was on some homemade speaker cabinets to go with the home brew hifi I made for my Mum about 45 years ago.
