<p>A vented loudspeaker system is provided which has at least one active driver (38 or 39) and a port opening (41) in a speaker cabinet (33). Disks or baffle plates (43 and 44) are mounted a predetermined distance from and perpendicular to the port opening, resulting in a vented system achieving an equivalent performance as would result from a flared, ducted port, but with several performance advantages and simpler construction. Flow guides (45 and 46) can be provided concentric to the port and attached to the disks or baffle plates and extending back into the port to block areas of stagant air and enhance laminar air flow.</p> |
