    Cool. I saw now that it's already been discussed. Will probably try it out in the future.

    Any sub can do DC, just hook up a small battery to the speaker terms and the cone will move one direction and stop. Reverse polarity and it will do the same in the other direction. Easy Piesy :p:p:p

    Static pressurization or rarefaction in a sealed room.

    Or unsealed if you can overpower the leaks.

    Nope, won't work except in a sealed room. But the fan above will do DC even in a leaky room.

    Rumor has it that he does not suffer fools, although it's also said he's happy to answer questions from actual users of his software.

    Andy, at the risk of getting on your banned list :D, can you create a little intro to your software here? I have heard through Don a few times the work you have not try to find the details on AVS. Where is the software. What does it do. Some results, etc.

    As payment, we will give you a few likes. :D

    Silence except for the possible sound of a distressed voice-coil.

    As RayDunzl said, at least IIRC from those long-ago grad classes, pressurizing the room is the equivalent of a DC signal. I suppose depressurizing could be a (-) DC signal. Don't get the bends.


    Whew, not me, at least not yet...
