KEF Introduces LSX Active Music System.

Grab a song you’re really familiar with and play around a bit with the phase correction. What you’ll hear with the phase correction engaged is a sharpness to the mids and highs (we dare not say hi-def, do we?) but even more stunning is the expansion of the soundstage in all three dimensions. Once you lock onto the difference you will actually be able to hear the soundstage of your favorite music with not only height and width, but with depth as well.
