Superb versatile speakers!

We are thrilled with these active speakers! The sound, in all types of music and speech, is excellent - detailed, musical and engaging. The connectivity is all we need, and the onboard streaming services are wide-ranging.
Using our iPads to control the speakers, and stream via Airplay and Chromecast, makes the speakers very versatile and convenient.
KEF have a winner here!

The Giant Killers

The LS50w2 makes a mockery of a great majority of large box loudspeakers. Generating a broad coherent image out of all proportion to their size. Visitors in disbelief mistook the source while my much larger respectable floor stand speakers stood idle, somewhat shamed.

My interest, is Jazz and Classical but a well recorded speaking voice can betray colouration but is perfect. Very heavily dependent on good source material, which is not a given, they simply shine with decent material. Wilson/Copland classical BBC R3 live classical and Danish Jazz a joy. A room full of kit and cables has been replaced by two small boxes, though wires are still present. With iOS devices the KEF Connect App works like a charm and is introducing me to web broadcasters, the ease of use and recall being exemplary. If the Mechanical Music feed doesn’t put a smile on your face you might need to try therapy. These things are wonderful, loving them.
