Portable Line-In SpeakersParameters:What is a haile?Pneumatic high (Air Motion Transformet pneumatic transducer, or said soprano, jet high) is to enjoy high reputation in the world of electroacoustic Dr (Dr. Oskar Heil) was invented in 1973, about its working principle is in the middle of the two poles, there is a special insulation film, film surface covered with a layer in a certain arrangement of wire, and this piece of plastic sheets of aluminium film, through the repeated folding as diaphragm components, when the current through the folded membrane can produce action, due to the magnetic field on membrane folds from creasing extrusion or Air inhaled Air, like the accordion radiation sound wave in the form of injection, the high-pitched call pneumatic monomer.AMT pneumatic diaphragm has a very large area of high units, more than or unwanted out-of-bandwidth harmonics and aluminum belt unit, can promote the air quantity is more, plus the quality of diaphragm is very light, impedance curve flat, high frequency extension, reaction speed is very fast, is a kind of very good coloration.It is possible to say that the pitch of a pneumatic high-pitched is slightly less noble, but the pneumatic treble is more powerful than the same size.Suitable for home and car tweeter or super tweeterParameters:Model Number:AMT-56Panel diameter:56mmDiagonal screw hole spacing:49mmOpen Hole diameter:42mmSpeaker height:18mmMagnet diameter:41mmMagnet width:10mmRated power:15WMax Power:30WImpedance:4 (4 ±15%)Sensitivity:90±3dbRecommend Crossover:>= 3500HzNET Weight:95g/pieceFrequency Range:3K-40k HzSound film Material:KAPTONPanel Material:AluminiumPackage included:1PC tweeter
