Why you will love it
Uni-Q driver array and Music Integrity Engine
Each speaker uses an 11th generation Uni-Q driver array with a 19 mm aluminium dome tweeter and a 115 mm magnesium/aluminium alloy cone. KEF says the Uni-Q array works as a single point source to widen the sweet spot.
KEF also lists its Music Integrity Engine digital signal processing and dedicated Class D amplifiers for the low and high frequencies in each speaker.


Plug and play to TV, desktop and more
KEF says you can connect your TV with HDMI ARC, your desktop or laptop with USB-C, and a game console with optical. A dedicated RCA output connects a KEF subwoofer.
Network streaming is supported up to 384 kHz/24-bit. KEF lists AirPlay 2, Google Cast, UPnP, Bluetooth 5.0, Spotify Connect, Tidal Connect, Amazon Music, Qobuz, Deezer, internet radio and podcasts, depending on service availability in your country.
Set up and control with the KEF Connect app
KEF says the W2 wireless platform includes intuitive onboarding and customising through the KEF Connect app. Its EQ settings let you fine-tune the speakers to your room or taste.
The two speakers connect with the supplied 3 m USB-C interspeaker cable. KEF says only the supplied cable or its C-Link interspeaker cable should be used for this connection.

Place them where you want
KEF lists the S1 floor stand and P1 desk pad as compatible accessories, so the speakers can sit on a shelf, a desk or a stand.
The connections are on the rear of the primary speaker.
Three finishes
