    'tis a shame about the noise as it is a beautiful piece of kit in all other respects IMHO particularly for the £2k I paid. I initially had the 5700 but we had mis-calculated so it wasn't quite able to fill the 7' screen hence the change to a 7200 which fitted the bill perfectly and is of course higher res (subject to what is connected of course).

    Wouldn't it have to be a (heat) conductive substance that also absorbed sound.
    A big metal box with fins and holes cut out in the appropriate place would do, but i can't think of an easy substance that does both.
    Most noise absorbing materials also insulate heat which is very undesirable for a projector in a box.

    Maybe two metal boxes, one inside of another connected via a heat pipe and foam in between would do. So the inner box absorbs the heat and transfers it to the out box and the foam inbetween would absorb any sound. But you still need holes for the connections and light to get through.

    Could use a rubber cealent(spelling) if all the cables where connected already then wraped in another piece of plastic. So all the connection cables go into a single wraped cable which is then sealed using rubber. For the front use a very clean piece of perspects or glass which is also held in place with rubber (to keep the sound from escaping).

    This is probably a bit over kill but would completely silence the projector, although access would be very dificult.
