Subwoofer Enclosures, Second Order, Infinite Baffle, Free Air
These are great for applications where trunk space is at a minimum and usually the easiest and least expensive way to add a subwoofer to most sedans. Not having to construct a box is an advantage, but many vehicles will require a new rear deck panel and/or vent to be constructed to accomodate even smaller woofers. These custom vents and panels could cost as much or more than a prefabricated or custom box.
Infinite baffle set-ups require a woofer with a beefier suspension for high power handling and one with better cone damping. This set-up will be less efficient in reproducing the lowest frequencies as compared to other second order or higher enclosures.
In any free air application, the back seat and surrounding panels should be removed to seal any possible areas where energy could be lost. It is crucial to separate (seal) the back wave of the loudspeaker (woofer) from the front wave of the loudspeaker. If not, bass cancellation will occur. This is also a good time to rid and deaden the trunk and surrounding areas of any unwanted noises and rattles.
