I honestly can't say which format is better, since I haven't spent any time evaluating them; however, 14K is a reasonable place to start thinking about cutting off, since higher frequency sound is probably going to be distinguishable only to dogs...

Then why do manufacturers routinely make speakers that respond up to 20,000 Hz? And I'm not talking about high-end audiophile stuff, either. I'm talking about average-quality speakers designed for the mass market. Why build in that capacity if no one will notice it?

Part of it is marketing, "These go to eleven."
