Abstract
A loudspeaker includes a first electro-acoustic transducer, a horn acoustically coupled to the first electro-acoustic transducer, and a first acoustic leak that is acoustically coupled to the horn. The first acoustic leak is positioned so as to reduce a peak in a frequency response of the loudspeaker at the targeted frequency without removing the targeted frequency from the output of the loudspeaker.
