    Hey All, Just wondering does anyone know if there are any instructions on how to make your own tactile transducers? I looked out on the internet but did not find anything. Just ads to spend $400 or more....geez.....

    you can get the aura bass shakers on ebay for about 25.00 a peice last time I checked, for the price I hear they do their job well, I plan on buying the Aura's and then down the road one by one replacing them with butt kickers

    I've found that a leftover 18" driver - mounted into the seating platform - does a very nice job [​IMG]

    There are several options for you:

    Buy a Buttkicker 2 (about $260)
    Buy some Aura's and mod them (to lower Fs)
    Build your own out of old drivers (there are "plans" on the net, I will try to find some old links for you.) This may seem to be the most cost effective, but in the long run probably isn't.
    I would buy the Aura's and mod them, for a cheap and solid solution. Send me a private message and I will send you a few pics of how I did it.

    Well what the Aura's are is a voice coil sans cone
    with a cork cap.

    When mounted the cork & coil attach facing the object
    (to be shaken)and the coil acts directly upon it.

    Of course there is more to it but thats the
    idea in simplicity. Don't see why a dremel
    to an old driver to remove the basket/cone
    and some clever mounting couldn't do the same.

    As far as transducers go I don't think the
    aura PRO's are available anymore and they
    are/were my favorite. Matched up to a
    monoblock amp it's far cheaper than the
    kickers..

    Dont care for the standard aura shakers not
    nearly as powerful and the big advantage to
    aura stuff is size relatively thin (1-2")
    where kickers stand proud BUT are well worth
    the money (they ARE better) there are more
    powerful transducers but with anything else $$$$

    I'll comment that I thought they were just such
    a joke until I took the plunge... Now I've got
    several arrays on every piece of furniture I
    could mount them on!

    FWIW

    Interested in the "mod" post up the deal

    I use them on the LFE which is only enabled when
    I want to use the shakers....

    LFE FREE!

    I just hooked up a pair of the aura standards to a friends couch and they worked pretty well. unfortunately he bought them on ebay with an amp. The amp wouldn't even move them wired in series (8 Ohm) and it got hot wired in parallel (2 Ohm). I would suggest getting 4 standards so you can wire them at 4 Ohm to a mono amp. Unless you have an old receiver setting around that you aren't using. You can still pick up a pair of these from Parts Express for 29 bucks. I don't know if I would ever want my furniture to shake more than 4 of these can produce but then again I've never felt any others.

    Jim what mod can you do on the aura shakers? Post a link if you have one. Thanks

    Here's my wiring:

    I run in PAIRS that are series wired. (8ohm)

    then 2 pairs are parallel wired into an AudioSource 5.3
    (presenting approx 4 ohm)

    So if by chance any "pair" fail the resistance LIFTS
    to 8 ohm as opposed to dropping below 4 ohm.

    This adds some protection to the amp and still
    allows removal of a pair if need be (back to 4 ohm)

    Thought shakers were so stupid until I took the plunge
    and now there's hardly a seat in the house without!

    HERE is an article I had in my favorites. It involves tearing apart an old driver and some gooey adhesives and is a PITA, IMO... especially since bass shakers are so reasonable.
