Prosceniums are often filled with sand and provide a firm bass absorbing place for your subwoofer and spiked fronts if applicable. You are right that GOM is used for acoustic transparency so that what is underneath it does the sound absorption to whatever degree you are trying to accomplish. HTH

Does it have to be any particular style? or is the GoM, etc. discussion primarily related to areas where acoustic transparency are important, like prosceniums? Thanks.
