A loudspeaker system includes an upper frequency assembly that radiates acoustical energy having spectral components in the audio frequency range above a predetermined upper frequency, typically at the high end of the bass frequency range between 150 and 200 Hz. The assembly includes a ported enclosure with a front face enclosing a loudspeaker driver with a cone adjacent to the front face of diameter slightly less than at least one of the height and width of the enclosure.
