Exactly: Which is why driver size makes no difference.
Oh. Wait. Driver size does make a difference. So it turns out that the maximum output is determined by size and how far it can move.
... and is frequency dependent.
Ok. So the maximum output is determined by driver size, how far it can move, and the frequency being output.
... and the effect of the baffle
OK. size, movement, frequency, baffle.. That's definitely it.
... and how well it couples to the air (see ported, transmission lines, and tubes)
That's so many other factors: I'm gonna have to say that Bill was talking out his butt. Feel free to correct me if I'm wrong here Bill.
