rob,
i think the gasket needs to be squishy so that when you tighten the bolts for the drive units the seal is made - but can be broken and remade when you fiddle with the wadding behind the drivers etc. iirc automotive gaskets are a one time deal and if you break them they need to be replaced.
ok new question.
i'm going to be honing my skills by building the stands first - these are very simple mdf boxes about 10 cm high. they are to be filled with dry sand however i've heard of different concoctions of different materials being beneficial in helping to damp / absorb vibration. does anyone have any recipies for this kind of thing? i was going to use dried sand as a base but mix it with packing foam, polystyrene peanuts and possibly some gravel and coal to get something with lots of different densities to help dampen vibration. good idea? idea worthy of a pneumatic bimbette? i throw myself on the mercy of the court.
cheers
