Acoustic suspension (air suspension, closed box, sealed box) is a method of loudspeaker cabinet design and utilisation that uses one or more loudspeaker drivers mounted in a sealed box or cabinet. Acoustic suspension systems reduce bass distortion that can be caused by stiff motor suspensions in conventional loudspeakers.

| - Acoustic suspension (air suspension, closed box, sealed box) is a method of loudspeaker cabinet design and utilisation that uses one or more loudspeaker drivers mounted in a sealed box or cabinet. Acoustic suspension systems reduce bass distortion that can be caused by stiff motor suspensions in conventional loudspeakers. A compact acoustic suspension loudspeaker was described in 1954 by Edgar Villchur, and it was brought to commercial production by Villchur and Henry Kloss with the founding of Acoustic Research in Cambridge, Massachusetts. In 1960, Villchur reiterated that: The first aim of the acoustic suspension design, over and above uniformity of frequency response, compactness, and extension of response into the low-bass range, is to reduce significantly the level of bass distortion that had previously been tolerated in loudspeakers. This is accomplished by substituting an air-spring for a mechanical one. Subsequently, the theory of closed-box loudspeakers was extensively described by Small. Speaker cabinets with acoustic suspension can provide well-controlled bass response, especially in comparison with an equivalently-sized speaker enclosure that has a bass reflex port or vent. The bass vent boosts low-frequency output, but with the tradeoff of introducing phase delay and accuracy problems in reproducing transient signals. Sealed boxes are generally less efficient than a bass-reflex cabinet for the same low-frequency cut-off and cabinet volume, so a sealed-box speaker cabinet will need more electrical power to deliver the same amount of acoustic low-frequency bass output.
