Wom165_vHE is the uncompromised 6.5' woofer to reproduce 35Hz - 2500Hz in High End products.

Its uses under-hung voice coil, built on Ø36mm Titanium former, and made of only 2 layers.

Thanks to the advanced and powerful motor structure, it ally strong force factor (6.8N/A) and negligible induc-tance modulation. The impedance curve shows the very low inductance value (Le = 0.085mH) which help to design efficient passive crossover.


The association of Kartesian innovation about the membrane, the spider, the pole pieces and the voice coil allow to reach very low THD (0.3% from 100Hz to 1000Hz with 90dB at 1m).
