acoustic suspension

noun

: an enclosed mounting for loudspeakers that produces a more defined acoustic tone at the cost of a reduced output

Acoustic suspension simply means that the driver is mounted in a sealed cabinet.

—Home Theater, June 1997

Note: Enclosing a loudspeaker (usually a woofer) in a small space causes the emitted sound waves to behave differently, allowing the speaker to generate cleaner sound but also reducing its efficiency.
