  1. For a friend who is at presently building a full body lion
    costume i am looking into a way to make the lion roar.
    What i will need is an amp and speaker as small as
    possible but with a high carrying range/distance.
    Only mono suits the purpose.
    Anything that we could build as compact as possible
    and that can be powered off a small 12V dry battery?
    Suggestions welcome.

    Any of the class D amp chips/modules should work. Googling gainclone will
    provide a lot of info on National's line of chips. The hard part will be
    finding a speaker that is small and still able to produce the sound level
    you want.
