I have already everything in place for masking my screen (winch, controls etc.) but my problem is what kind of cloth to use since when I'm playing 1.88 or 1.65 the left and right speakers will be covered by this cloth.
I know that Harkness have a special cloth that let's the sound through for this purpose but's it's not cheap, are there any types of cloth that can be used for this purpuse ?

black speaker grill cloth will work with a leading edge of black felt

Also I've used black china silk with good results -- RTA shows it to be acoustically transparent and it may even be cheaper and perhaps easier to find than speaker grill cloth. It is not as light absorbing as a good felt, so as Gordon says, you still need a leading edge of velour for your mask to adaquately block any image spill.
