There used to be a difference in East coast type sound as represented by AR and west coast as represented by JBL. These distinctions are not as meaningful in the current enviroment.
But essentially JBL and Klipsch both used horns to greater or lesser degrees. They had/have are highly sensitive with a more forward, agressive, defined sound compared with the less sensitive British sterotypical sound wich is typically more polite, laid back, and sweeter. Many will fall back on the analytical versus musical peaker debate. My own experience having taken a liking to a very analytical speaker which is French (Focal) and hearing other French speakers which are more the musical type (Triangle) that I safely conclude there is no specific National sound!
