What does Uni-Q actually do?

It mounts the tweeter at the acoustic center of the midrange cone, so high and middle frequencies come from one point. The practical result is a wider sweet spot and a sound that changes less as you move around the room.

Does ARC versus eARC matter?

For a stereo pair, rarely. Both carry stereo TV audio cleanly. eARC adds bandwidth for lossless multichannel formats, which matters more if you might connect other gear through the speakers later.

Can either stream from Spotify?

Both can over Bluetooth. Only the Cambridge has Wi-Fi, so only it can stream directly from the internet through its StreamMagic app.

Head to head

KEF Coda W vs Cambridge Audio L/R M

KEF's Uni-Q point-source pair against Cambridge Audio's streaming pair with eARC. The deciding factor is Wi-Fi streaming and power versus imaging and price.

Both pairs take a TV feed over HDMI, have a moving-magnet phono stage built in, and include a subwoofer output, so either can be the whole system in a living room. The KEF's Uni-Q driver places the tweeter inside the midrange cone, which widens the sweet spot. The Cambridge adds Wi-Fi streaming, eARC rather than ARC, and half again the power. The one question that decides it: do you stream over Wi-Fi, or is Bluetooth enough?

Pick the KEF Coda W if

You want a wide sweet spot, so the sound holds up for everyone on the sofa and when you stand.
Your music comes from a phone, and aptX Lossless Bluetooth covers it.
You want the lower price and a pair you can buy today.

Pick the Cambridge Audio L/R if

You stream over Wi-Fi and want a proper app rather than Bluetooth.
The room is larger and the extra power matters.
You want eARC so the speakers stay future-proof for lossless TV audio formats.

Verdict

Buy the KEF Coda W if imaging and price come first; Uni-Q's wide, even dispersion is the most distinctive thing in the category, and aptX Lossless is excellent Bluetooth. Buy the Cambridge L/R M if you want Wi-Fi streaming and more power, because the KEF has no Wi-Fi at all. The exception is availability: the KEF can be ordered now, while the L/R M is a pre-order and neither has a full measured review yet.
