Definitions for "Acoustic Suspension"
A speaker system mounted in a sealed enclosure. The internal air loading adds damping and acoustical stiffness at low frequencies where the wavelength is larger than the enclosure. [Go to source
A sealed speaker enclosure that makes use of the air behind a woofer to control cone movement.
A type of loudspeaker enclosure design, made popular by the Acoustic Research AR3 among others. The cone of a driver is suspended by a "surround" (see the driver cutaway drawing) which acts like a spring, to restore the cone to its central position. The air in a sealed enclosure also acts like a spring, and is used as such in this design. The result is a lower resonant frequency, and lower bass, than would otherwise be obtainable. These designs also typically use an enclosure filling material that makes the enclosure act larger than it really is. See the section on Thiele-Small analysis for greater detail.
