The LS50 mini-monitor loudspeaker is a reinterpretation of the research, design and engineering approach of the legendary LS3/5a Monitors using KEF’s latest technologies.

Despite its compact size, the LS50 commands astounding sound-staging, imaging, and time-domain alignment. This can only be achieved through the unique arrangement of the drivers found among KEF’s top of the line products.

KEF’s groundbreaking Uni-Q driver arrangement operates by housing a discrete tweeter in the center of the mid-range (treble/bass) unit. This allows both the entire sound field created by the speaker to originate from a single point in space, meaning every sound in the entire spectrum reaches your ears with precise alignment. This produces a truly natural sound; a sound capable of convincing the listener they are hearing a live performance. Because the audio originates from a single point, you can stand anywhere in the room and hear a performance more precise and realistic than other speakers can provide.

So while at first glance the LS50 may appear to only have one driver (per speaker), what you are seeing are two independent drivers, working together to give you an unmatched experience.
