Small cone tweeter with ferrofluid. This tweeter removes all doubts about
using a cone tweeter in hifi systems. The voice coil is cooled and damped by
magnetic oil, and this viscous damping eliminates the rise in resonance. The
impedance curve is nearly linear and it is therefore very easy to make cross
overs for this speaker. An absolute excellent tweeter for use in smaller hifi
systems especially as tweeter in satellites.
