[QUOTE="audioholic, post: 722280, member: 549629"] Balloons simply wont work, at all. Think about it, without the balloon, you are compressing the air inside the box. Add the balloons... the air inside the balloons simply compresses too. I doubt adding flexible rubber containers (balloons) filled with air would change perceived air volume inside the enclosure at all. The expandable foam doesn't work well either, as its way too porous. The reason it weighs nothing is because once its expanded, its made mostly of air, which doesn't really help to displace air inside the box. You need something solid. [/QUOTE]
