Product Details

Tymphany PMT Series 20N12AL04 1/2" Aluminum Dome Micro Full Range Speaker Driver 4 Ohm

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).

How can you attach those drivers to the enclosure? Do you have example?

Asked by: raymonk
This driver is designed to be rear mounted and help in place with a sort of clamp on the back of the driver.

how much more power would this handle when crossed in the 8 kHz - 12 kHz zone?

Asked by: speakerfreack
The power handling of the driver will not change, although the output will increase since it is not trying to reproduce low frequencies.
