Wom145_vHE is a very high quality 5' woofer designed to cover 45Hz - 3000Hz in High End products. Its uses an under-hung voice coil, built on Ø26mm Titanium former, and made of only 2 layers for very low inductance value (0.04mH).


The motor structure uses two high grade NdFeB magnets, a cooper ring and specific devices to manage the inductance modulation. It uses rigid and damped CGF cone and low mechanical lost surround for fast and clean transient response.


Thanks to the dynamiK spider, the Fs[Hs] remains unchanged on the full excursion, providing same accurate bass reproduction on wide dynamic range.
