The sound behind the vision

LSX Soundwave Edition

Great design by Terence Conran but as my first KEF purchase these speakers are exceptional. With a bit of required fine tuning with the KEF app, the soundstage and quality is really good. I listen with Spotify and wireless connection works well but sounds are price, detailed and far better then other speakers I have listened too. Airplay 2 and optical inputs work really well also so very good connectivity, These speakers maybe be designed to be used in a small room yet the sound (without sub) sounds like the bigger brother. Highly recommend.

The best small speakers - LSX Soundwave Edition

These have been the best purchase I’ve made for a very long time. They make the TV sound great via their optical input plus we always use Spotify connect. The app lets you tweak the sound if you don’t have the speakers in the ideal position which is a huge help as we have to put ours on a bookshelf rather than stands. Highly recommended.

LSX Soundwave

This is my first adventure with KEF, it has opened my mind to a new world of audio enjoyment. Simple to set up, beautiful looking, and the sound is 1st Class. I will be back soon !!!!!
