Wib145_vHE
The Wib145_vHE is a High-End wideband able to reproduce the bandwidth from 45Hz to 20 000Hz.
Wib145_vHE is one of the very rare wideband using an underhung voice coil to ally very low moving mass (8.5g)
and pure linear motion over +/-6mm. Thanks to this technology, it becomes possible to play accurate low fre-
quency and detailed high frequency.
The motor structure uses 2x high grade NdFeB magnets and a long cooper ring to reduce inductance to 0.04mH at 1kHz, which is comparable to tweeters.
The cone is made of CGF to offer optimal damping and avoid excessive lagging in the midband frequencies.
The dust cap is an inverted Aluminium dome, directly attached on the voice coil Titanium former.
