HIGH RESOLUTION SOUND
As you might expect from people who are obsessed with high resolution sound, the beauty of the M400 is more than skin deep. With KEF’s ultra-light 40mm neodymium driver and copper clad aluminium wire (CCAW) voice coil, the M400 reveals all the glories of the original performance: crisp, intricately detailed highs, seamlessly fluid midrange and tight, clean bass. Music you can feel – and so realistic, you can almost touch it. Your favourite tracks never sounded so good.
