I'm in the process of remodeling my house, and we probably have to enclose my sub-woofer in a new wall/cabinet that will be built. My question is this: Since the sub-woofer's sound is omni-directional, and very low frequency, will the sound penetrate drywall? My sub-woofer is floor firing, which I know is not the ideal type for this type of installation. If it won't "work" through the drywall, I will put some type of grill/mesh in the opening. Either fabric or metal. Any thoughts? Thanks for your input.
