If a loudspeaker were to be installed in a baffle of infinite size, there could be no acoustic short circuiting. However, a baffle of infinite size is hardly feasible. In day-to-day practice, things are different. The limiting frequency of a baffle is the frequency at which the "acoustic short circuit" becomes noticeable. The finite size of a baffle means that very low frequencies are lost. Since baffles propagate sound both towards the front and towards the rear, they have dipole characteristics which give them very good spatial qualities.
