Voxativ loudspeakers and drivers

Basically they use a whizzer cone instead of a crossover. This can sound very good and needs less power than a speaker with a crossover. It is also like a single point source so should image very well. It was the preferred approach for car stereo for many years. Now modern speaker systems for cars are usually three way - subwoofer, woofer mid range and tweeter - as this increases the accuracy of the sound with less break up distortion and lack of linearity from the use of a single cone.
