Acoustic Suspension Speaker Cabinets

Have you ever wondered how Acoustic Suspension speakers.lifetips.com/">Speaker Cabinets work?

• A speaker mounted in a small box will compress the air inside when the cone moves inward
• The air then pushes on the cone harder than the air on the outside
• The speaker will expand the air in the box when it moves outward
• The outside air will be pushing harder than the inside air

By using this pressure to restore the speaker cone to neutral, a much smaller box can be used to get deep bass. The trade off is efficiency (it is lower). Acoustic suspension dominated the speaker designs of the 1960's and 1970's as big, solid, state amplifiers were being developed to provide the needed power.
