Abstract
A loudspeaker with a pair of speaker units and a manifold chamber between the speaker units for combining the sound from both speaker units. The manifold chamber is formed by walls having an exit opening and a pair of rectangular apertures, the apertures confronting each other on opposite sides of the chamber and the exit opening being disposed normal to a plane centrally between the apertures, and the apertures and exit opening having parallel axes of elongation. One of the speaker units is coupled to each of the apertures to direct sound into the manifold chamber, and the manifold chamber is provided with a wedge confronting the apertures to direct sound parallel to the central plane between the apertures toward the exit opening. In one construction, a horn is coupled to the exit opening to conduct sound from the manifold chamber. Also in that construction, each of the speaker units has a vibratile cone confronting the apertures to which it is coupled and the cone is disposed in an enclosure provided with a bass reflex port. In another construction, four speaker units with vibratile cones are coupled to four apertures in walls forming a single manifold chamber with a single exit opening. In still another construction, a compression driver is coupled to each of the apertures through a transition section of the driver.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
