gday, just thought id tell you guys, my close mates dad makes this and i was talkign to him and giving him a dmeo of my system and he suggestedi shoulf build my bbox out of it, so i went to his factory and picked up a tonne of the stuff, got home and started cracking with it, its 50mm thick and its completely solid, he has video of an elephant walking over a sheet of 6 x 4 and not breaking, but anyway i built my spl box out of this stuff and it is awesome 0 flex, nothing at all and its plenty dense enough to drill into, ill get some pice up for you by the end of the week, it looks cool caus you can see the straw on the ends where ive cut to size
just thought id tell you,
