Outdoor Speakers

in DIY
I would like to build some speakers for my backyard deck so i can smoke ribs and listen to music. It is an open air deck.  No walls or ceiling.

I need them to be weather proof.

What kind of drivers should i think about to perform in an open air space?  Is this a good application for horns?  I do not know much about horns.

Thanks!
Chad

    Lots of pro drivers are described as having waterproof cones and surrounds. I don't know if that means occasional sprinkles that get wiped off, or a soaking downpour that lasts 3 days. You might call the folks at usspeaker.com
    Since it is 4 pi outdoor space, high efficiency would be good also. Another plus for pro drivers.

    But Chahly - Stahkist don't want speakers that look good, Stahkist wants speakers that sound good!

    exciters?

    Has anyone tried to "crossover" exciters?  Like put one on a thin carbon fiber material and only send 10-20KHz to it.  Then put one on plastic and send 400-10K Hz to it.  Then put one on a hollow plastic shape for 20-400Hz.  Kind of a exciter "di-pole" on different materials?

    OH thats right after looking at exciters they make those bass shakers that can handle the low end.  I think this could be a really interesting experiment to try to make at two way or three way exciter array.  I guess the is the best term for what i am thinking.

    I also see an application for those with 3D printers.  How can we use an exciter with printed materials that will help shape the sound?

    After many of the, IIRC, daex32ep failing, some during the first frequency sweep, I came to the conclusion that they behave similar to normal speakers in that the resonances of a 'panel', especially the lower frequencies, can 'overdrive' the xmax of the exciter.  Before ending the experiment, my thoughts were to make more of a conventional 2-way using a bass shaker for the lows and crossing to a smaller panel/exciter for the mid/highs.  This could also be done on one panel simply by separating it by cutting a channel across it serving to terminate resonances.  Also wondered about placing everything on the same panel, sans any channeling/grooving, and seeing what happened. 

    There's very little our there where the average diyr' can model the panel/exciter placement/resonances, that I am aware of.

    Google marine speakers. It looks like the car audio folks make drivers for boats too.

    After a little more thought, placing both the bass shaker and the smaller exciter on the same panel might be a bad thing as the resonances of the bass shaker might overdrive the smaller exciter.

    Thanks Ron_E.  The marine drivers are interesting.  Some even have LED lights so i can have a light show while listening!  :)

    Heck they even have waterproof revievers with bluetooth and other protocols.  I just need to power it.  I could build this whole setup into the grill table on my deck.
