Hi guys, are all the GOM styles acoustically transparent or only certain ones?

any breathable double polyester fabric should do. However the ones touted for acoustic applications are FR701 style 2100.

Acoustical transparency is a matter of degree -- nothing is 100%. High frequencies are always attenuated to some degree. Generally, you need only be concerned within the Guilford line if you want to use a fabric as a speaker grill cloth, or if you have had a high-performance acoustical design done which critically relies on a specific sound absorption balance.
