The PF-1203B has been designed specifically for both direct radiator and horn loaded mid bass applications. This PF Series design has been optimized for use in the critical 60Hz to 3000Hz vocal range and is an ideal choice for professional level three way designs. A typical 12 inch design must offer both good bandwidth, down to 60Hz, and good efficiency. The PF-1203B has all of its performance designed into the 125Hz and above range. This means that the efficiency can be optimized for this frequency range. High efficiency means that lower electrical power levels are required, thus improving both system relia- bility and reducing power compression.
