Higher sensitivity - more dynamic sound?

More dynamics if the speaker is of proper size better transient response less thermal compression in a home environment the ability to use almost any amplifier type made. Can sound better at low and high SPL levels.

A 110db horn running off 20 watts will not see any heat that can cause compression a 86db speaker requiring over 250 watts will be near melting at peak SPL levels. A horn also has better throw so at distance, its SPL level isn't dropping as fast as a standard dynamic speaker design. Standard dynamic designs can sound pretty darn nice but they are toys when compared to a proper large horn speaker. Now I know most cant house anything over a toaster-sized box or overly slim tower and they don't want to consider that larger is better even though the brand of small boxes they bought most likely has a much larger model as the top of the line.

{I see no physical mechanism by which a horn speaker would throw better than a dynamic speaker} You can not see the horn on a horn loudspeaker? Horns decrease SPL less at distance than a conventional dynamic design think radiation pattern control. Good luck.
