  6. Motor structure

    in General Audio - Can't find a category for your question? Ask here.

    This part of driver tech i'm a little weak on. My two basic questions are what would happen if the pole piece was removed from the structure (not questioning cooling) and what effect do different coil placements have? IE: If the coil was completely out of the gap at rest, completely centered in the gap at rest, or 1/2 entered into the gap at rest?

    I can pretty much easily assume that if the coil is too far from the gap it will produce very little magnetic force.. but how far is too far?

  8. Wanna donate your PC's time for a while?

    Over on Xtremesystems.org (PC and Overclocking Enthusiast website) we're having a supercomputer challenge for WCG (World Computing Grid). If you've heard of Folding@Home or Seti@Home or anything like those, that is the basics of what WCG is. Here's the offical thread: http://www.xtremesystems.org/forums/announcement.php?f=144&a=75

    If you are unfamiliar with what those programs are, then this is what it is in a nutshell: It is AIDS, cancer, and Muscular Dystrophy research. There are a few other projects thrown in too, but those are the main ones that most of our team focuses on (we're almost the #1 team in the WCG project btw).

    Anyways, to keep this short, if anyone is interested in donating a week (or staying around for longer) for the challenge they can find all of the information required to join in on it here (takes 5-7 minutes): http://www.xtremesystems.org/forums/showthread.php?t=230613

    If you do join, maybe put something like "[sMD]" at the front of your username to denote where you originated from as well, if you can :)

    I should also let you know that the program is processor intensive. For most systems it will be perfectly safe to run, but there's always those 5-10% of horribly designed ones.. or that are on their last legs lol ;)

    Thanks for your time guys, hope to see a couple people kick some resources in :)

    If you register on the forums to ask questions i'm also known as "STEvil" there. Registrations are all done manually and you dont always get a notification so if you havent had one for a few days just try logging in and posting ;)

  19. Quick ? about Tunnels

    in Subwoofers / Enclosures

    Posted

    If both ports are identical internally, yes.

    If they are not, no.

    There's a way to make the Aeroports even more effective 'though i'm too lazy to dig it up right now. If you google for a XXX18 in 20ft^3 enclosure and look around long enough for the build log i'm sure you find it.

    The key for maximum efficiency of that effect would be the size of the tunnel. Based on the subs/power/roll off would determine the appropriate mass of air inside the tunnel and create it.

    The problem is testing. The design takes so much effort that nobody (that I know of) takes the time to build it over and over to derive any tunnel equations since they would include some kind of factor that uses the cab space as a variable. I for one would love to see it done though.

    I think all we need to do is make the tunnel a bit longer and taper the exit, like a horn throat ;)
