Last halloween, I took one horn/driver and placed it in the
garage and I broadcasted spooky sounds to scare the little
ones trick or treating, people said they heard the screams
a few blocks away, more people came to my house to check it
out.

They are "fun" horns. hehe

If you want to use there in your home, it would work great
if you had a large listening room, perhaps a listening room
the size of a sports arena - hehe
