A speaker system configuration and design and method of manufacture of same to reproducing stereo sound in a room using drivers placed on top and sides of a single speaker enclosure. The speaker drivers are supplied left (L), right (R), and left plus right (L+R) sound and configured to achieve sound power directivity of less than approximately 4 dB and sound power directivity variability of approximately ±3 dB over the frequency range of approximately 20 Hz to approximately 16 k Hz through speaker placement. A front driver may be added to the single enclosure c by radiating L+R stereo sound through the top and front drivers, while radiating L stereo through the left side driver and R stereo sound through the right side driver. A two speaker configuration is also provided wherein top and front firing drivers include L+R sound, while left facing drivers radiated left (L) sound, and right side drivers radiate right (R) sound. |

1. A method of manufacture of a speaker system designed to reproduce stereo sound, including a left and right channel, from a single speaker enclosure with a left side, top side, and right side, the method comprising:
placing at least one acoustic driver on the left side of the speaker enclosure, at least one acoustic driver on the right side of the speaker enclosure, and at least one acoustic driver on the top side of the speaker enclosure in a manner whereby the reproduced stereo sound is characterized by (i) sound power directivity of less than approximately 4 dB and (ii) sound power directivity variability of approximately ±3 dB over the frequency range of approximately 20 Hz to approximately 16 kHz, the acoustic driver on the left side of the speaker representing the left channel of a stereo signal, the acoustic driver on the right side represent the right channel of the stereo signal, while the at least one acoustic driver on the top side radiates at least one of the left channel, the right channel, and a linear combination of the left and right channel of the stereo signal. |
