The PMT Series family of micro speakers, from Tymphany, is designed for maximum full-range bandwidth, while maintaining superior off-axis response.Tymphany built the 1/2" 20N12AL04-04 PMT Series premium micro transducer for computer, television, micro array, and similar modern audio applications. It features a neodymium motor, light aluminum cone, and high-temperature polycarbonate frame that is designed for minimum center-to-center mounting distance and reduced comb filtering.
A low 359 Hz resonant frequency allows the 20N12AL04-04 to reproduce frequencies lower than most drivers this size (350 Hz), while maintaining an average sensitivity of 79.5 dB (2.83V/1m) from 400 to 20,000 Hz. Using four drivers in a series-parallel group increases sensitivity to a respectable 85.5 dB (2.83V/1m).
