ABSTRACT:
A satellite speaker system includes a side firing low mid driver mounted in a sub-enclosure which is vented into a second sub-enclosure through an acoustic resistance vent and to a third sub-enclosure through a variable aperture second vent. The vents further serve as pivots to allow the side-firing speaker to be rotated through a predetermined range, simultaneously varying the aperture of the second vent. The pivots are isolated by o-rings to provide an airtight seal to the sub-enclosures, as well as to provide vibration control. Third, fourth and fifth resistively damped vents allow the first and second sub-enclosure to establish acoustic communication with the environment. The front firing driver/s that reproduces the mid and high frequencies are mounted in a fourth sub-enclosure.
