The P Audio SD-44BN is a medium format compression driver that utilizes a precision formed diaphragm assembly. The titanium diaphragm is precision formed to ensure excellent consistency and performance. The diaphragm assembly is close spaced to a precision phase plug to ensure excellent acoustic loading. The SD-44BN has an operating range of 1200Hz to 20000Hz and is ideally suited for two way and three way high frequency applications in professional sound reinforcement systems.
The SD-44BN is a neodymium based magnetic system with an industry standard 1 inch (25.4mm) exit diameter. The mounting configuration is a standard "bolt on" style. P Audio offers a wide variety high frequency horns that will provide excellent pattern control and acoustic loading for the SD-44BN. The uses of neodymium magnetics allows the SD-44BN to be used in close spaced array designs such as modern high output line arrays.
The diaphragm assembly is a 1.75 inc (44.4mm) diameter commercially pure titanium design and utilizes P Audios very high temperature adhesive systems and precision manufacturing to ensure high power handling and reliability. The construction yields a full 50 watts of power handling capacity. The larger diaphragm diameter (1.75 inch) provides superior mid band response and is an excellent choice for medium power professional sound reinforcement systems.
