ABSTRACT:
A speaker enclosure assembly (10) having an enclosure cabinet (11) in which a speaker (26) is mounted. The speaker (26) creates an airflow within the enclosure cabinet (11) as the speaker (26) is vibrated for the transmission of sound. The airflow tends to resonate as it is bounced off of the upper, lower, front, rear, and side and end panels (14, 16, 17, and 18) of the enclosure cabinet (11), and is directed into a first baffle duct (31). The airflow is redirected by the first baffle duct (31) into a smaller second baffle duct (55) wherein the airflow is compressed to increase the resistance of the airflow, which exits the enclosure cabinet through an audio port (70) formed in the enclosure cabinet (11) to reinforce the sound from the front of the speaker (26).
