To be noted

Our innovative dual chambers design, associated with our dual magnets motor structure provides a very low THD until the lowest frequency.

THD doesn't exceed 0.5% from 1500Hz to 20000Hz when this tweeter is producing 90dB (A] at 1m.

It means perfect working condition for the most demanding recording studio.

Application example

Loudspeakers used:

Elegante HiFi speaker system, only 150mm wide, which cover 40 - 22000Hz (-3dB) with very smooth and accurate sounding.

The efficiency is 90dB/2,8V/1m

The passive filter is set at 3000Hz, 12dB/Oct.

Two vents on the back side tune the enclosure at 40Hz
