This is not a horn speaker. It is a hybrid speaker that includes a horn. OK, OK, I know I have made this point before, and I promise this will be the last time. I probably wouldn't volunteer to be the terminology police this time if I weren't a bit in my cups. I don't want to become a disdained outcast for failing to get with the program and call hybrid speakers horn speakers, but the difference is neither subtle nor unimportant. I can't believe you guys can't hear the difference between horn bass and direct radiator bass.
In my mind it is analogous to the situation which would exist if a recipe called for a goose, but since geese are large and unruly you decided to use a duck instead and just call it a goose. I promise that from now on I will call ducks geese to try to fit in on what is otherwise an excellent forum.
