THIS IS A “BUILT TO ORDER” PRODUCT

The EEN4FR-8A creates voice range sound engineered for aerospace interior cabins. An aluminum basket and neodymium magnet reduces this speaker’s weight from the more common stamped-steel basket. The wire harness connects with the 4-40 screw terminals for a strong mechanical connection without solder. This speaker meets applicable Federal Aviation Administration’s testing standards in DO-160F & DO-214.
