To be noted

The force factor measurement shows a perfect linearity on +/-4mm , which is one of the best performance available on the market (for a 5" inch mid-woofer).

This wide linear excursion ensure a very low distortion rate on the full power handling scale.

Furthermore, we use our .dynamiK spider which provides linear Cms(X) on +/-6mm.​


We recommend to use our Wom145_vHE in J.J.Bacquet configuration (Woofer - Tweeter - Woofer), from 40Hz to 3000Hz, in very demanding systems

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.
