The simplest box type system is a sealed enclosure. Note: Free-Air™ is a trademark of Stillwater Designs (Kicker) In this system the woofer has the front of its cone isolated from the back of its cone by mounting the woofer to the rear deck or on a board placed across the back of the rear seat.Īdvantages of this design include simplicity, minimal occupation of space and lower cost due to not having to have a box type enclosure.ĭisadvantages of this design are a larger power requirement, difficulty (sometimes extreme) in completely isolating the two sides of the cone from each other, and slightly less accurate sound reproduction. The simplest enclosure type is an infinite baffle or free air system.
