PH-112

 

 

 

 

 

 

  • The frame is die-cast alloy
  • The case is made from specially formulated pulp with fiberglass and wool
  • The cone is light in weight and very rigid. The surround and spider are quite stiff and the bandwidth is wide
  • The magnet is made from y30 high flux strontium ferrite. The magnetic structure weights 6.15kgs
  • The diameter of the voice coil is 3-inch edge wound with flat aluminum wire on a Kapton former.
  • The diameter of the diaphragm is 2-inch which is a very light and thin titanium. The voice coil is edge wound with feat aluminum wire on a Kapton former. The efficiency is very high and the high frequency response is very good
  • The throat diameter of H2/44/01Z is 1-inch whose cross section area is about equal to the total cross section areas of the circumferential patterned slits of the phase plug but less than 1/3 of the diaphragm. When the diaphragm vibrates, there is a high pressure zone built up between the diaphragm and the phase plug. The radiation impedance is high as well as the efficiency.
  • Without the phase plug, the radiation from the center of the diaphragm or cone and the radiation from of the edge reach the throat at different time as the distances are different, and there are therefore phase difference
  • With the phase plug, the radiations from the center and from the edge are traveling at equal distance. When these radiations reach the throat, they are in phase.
