Veteran's Org that would take 5.1 speakers?

Hi Everyone,

I’m near Los Angeles and getting rid of a number of components en masse. Including a mixed 5.1 speaker system and very nice Hsu subwoofer.

I would really like to donate them to a veteran’s org to either use directly or sell. Suggestions?

Of course, I could sell them in bulk, and donate the money, but I'm looking for any ideas better than that.
