A speaker system comprising: a speaker enclosure including: a front end for facing a listening area (18, 20); a rear end for being mounted to a mounting surface; and a first transducer positioned within the speaker enclosure for transmitting acoustic energy from the rear end towards or into the mounting surface to prevent an interference dip in a frequency response with the transmitted acoustic energy in the listening area (18, 20), the interference dip occurring at frequencies where a path length difference between a direct wave of acoustic energy and reflected acoustic energy is equal to half of a wavelength; characterized by a cover for being mounted to the rear end of the speaker enclosure such that the first transducer faces the cover and the mounting surface, wherein the cover includes a first section, a second section, and a third section, wherein the first section includes at least one mounting device for interfacing with an engagement device on the mounting surface, wherein the first section is positioned directly in front of the first transducer and extends in a first plane that is parallel to an outer surface of the speaker enclosure that faces the mounting surface; wherein the second section extends between the first section and the outer surface of the speaker enclosure and is configured to couple the first section to the outer surface of the speaker enclosure on a first side of the first transducer; wherein the third section extends between the first section and the outer surface of the speaker enclosure and is configured to couple the first section to the outer surface of the speaker enclosure on an opposite side of the first transducer; and wherein each of the second section and the third section includes a plurality of passageways for enabling the acoustic energy to pass therethrough and generally towards the mounting surface such that the acoustic energy propagates around the speaker enclosure. a speaker enclosure including: a front end for facing a listening area (18, 20); a rear end for being mounted to a mounting surface; and a front end for facing a listening area (18, 20); a rear end for being mounted to a mounting surface; and a first transducer positioned within the speaker enclosure for transmitting acoustic energy from the rear end towards or into the mounting surface to prevent an interference dip in a frequency response with the transmitted acoustic energy in the listening area (18, 20), the interference dip occurring at frequencies where a path length difference between a direct wave of acoustic energy and reflected acoustic energy is equal to half of a wavelength; characterized by a cover for being mounted to the rear end of the speaker enclosure such that the first transducer faces the cover and the mounting surface, wherein the cover includes a first section, a second section, and a third section, wherein the first section includes at least one mounting device for interfacing with an engagement device on the mounting surface, wherein the first section is positioned directly in front of the first transducer and extends in a first plane that is parallel to an outer surface of the speaker enclosure that faces the mounting surface; wherein the second section extends between the first section and the outer surface of the speaker enclosure and is configured to couple the first section to the outer surface of the speaker enclosure on a first side of the first transducer; wherein the third section extends between the first section and the outer surface of the speaker enclosure and is configured to couple the first section to the outer surface of the speaker enclosure on an opposite side of the first transducer; and wherein each of the second section and the third section includes a plurality of passageways for enabling the acoustic energy to pass therethrough and generally towards the mounting surface such that the acoustic energy propagates around the speaker enclosure.
